Electrical-wiring - Batteries - Cadillac - Deville :: Car Randomly Losing 100% Electric Power
May 19, 2015
Was driving one day, and when I came to a stop sign, the car just died.. I couldn't start it up, so I pushed it to the side of the road.. I tried to turn the key again, and it fired right up... No issues for about a week, but then I came outside one morning, and the car was completely dead. No interior lights, dash wouldn't light up, nothing. (no cranking noise when you try to turn the key) I assumed it was because the battery was old, and the car had just been sitting there for about a week without being started up. I was about to give it a jump, but when I opened the door, the lights came on. I put the key in the ignition, the dash lit up, and the car fired right up.. No issues for about a week, until again, came outside, car was completely dead..
I used my other car to run up to the store, and when I came back, decided I would try to start up the DeVille again. Randomly, upon opening the door, the cabin lights lit up, and sure enough, car fired right up... no one had touched the car while I was gone.. I drove the car up to a shop near my house, where they tested the battery, which tested good. Terminals are all clean, and he made note that the ground connection to the car was also firm and clean. He offered to run a diagnostic the following Tuesday for $125. I returned home, drove the car once more over the weekend, but when I went to start the car Monday, it was again, completely dead. It's been over a week now, and I haven't been fortunate enough to get it to start. I again tried this morning in hopes that I would get lucky, but it's still completely dead.

Car started losing electrical power on the way home from work last week. Dim lights, blower stopped, wipers stop, almost stalled out when getting off the interstate. Barely made it home. 30 minutes later went out to troubleshoot and it started right up. Ran for about 2 minutes and stalled out from lack of electricity. Put voltmeter to alternator and it seemed to only be putting out 8.5v. Took to store to have tested. Replaced alternator and it didn't work. Reman alternator still seemed to only be putting out 8.5v or so.
Checked fuses and cleaned battery terminal and verified good block ground and good body ground. Still having problem. 1996 Taurus. What next? Battery is exactly 2 yrs old and was putting out 11.6 when the problem first started last week. Due to cold and this existing issue, battery is only at 6.5v right now. Can jump the car, but then after removing jumper cables car dies in 30 seconds. Should I have the battery tested? What else could/should I be looking at?

This evening I drove our Subaru Legacy Wagon (1999) about 3 miles or so to the gym. When I pulled into the lot, I noticed my radio (tuned to NPR, no less) had gone off. Curious! A few seconds later, dashboard lights come on (ABS, maybe others). After that, engine goes quiet, car is dead -- turning the key does nothing at all, and the car is completely without power. Only the dome light works, and barely. I get a jump, and eventually the car starts back up --- but it took a while, and several tries, before I could get the engine going.
On the way home, I kept a careful eye on the RPMs -- when I was close, I noticed the ABS light pop back on, and the RPM needle go down to zero. I tried my best to keep the RPMs up by staying in first, and managed to park. Of course, the car was unresponsive when I immediately tried to restart it. Some quick internet searches suggest alternator, bad connections to the battery, and some other ideas. We've never had this problem before. The twist is that we're literally on the brink of selling this car -- we've got one more than we need. Thus, we'd be pretty bummed if we had to put much, if any, cash into the car just so we can get rid of it days later.

I am curious if it is possible to make a stand alone controller for the electric shift transfer case in a 2000 F-350?
The reason I ask is, this is swapped into a 4x4 conversion in a van and I would like the transfer case to work like the factory, but I don't want to swap over the whole GEM module. I have the high to low and low to high shift relays and wiring, the selector switch from the dash.
I know that powering up the relays will shift the transfer case, but the GEM module tells when the relays need to shut off, and that is where I am not sure what to do. I am assuming that the other plug on the shift motor (6 pin plug) is the sensor that tells the GEM module where the shift is at.
What needs to be done (with a bank of relays).....

My 2002 GT 3.8 with 157,000mi has recently and randomly been losing total electrical power after starting the engine. Engine fires like a champ then after 2-3 seconds will completely die- no engine, no lights, no radio, no locks, nada. The key will be stuck in the ignition and can remove it after playing with it. After a time that I haven't been able to determine, electrical power will be restored after I reinsert the key. Sometimes she will stay running after restarting: sometimes not. But she never hesitates to start.
After the first occurrence she ran fine for 3 days but did notice the driver information center would flicker. It never went completely dark, but go from bright to dim- which has previously never happened.
The car has been parked outside and it has been raining quite a bit- I did notice a few times there has been water on the passenger side floor. I had this problem years ago and it was supposed to have been fixed at the shop.
Also of note: I've had the known GP ignition lock issue where the key will not release for the past 3 years. Just been using a pen to manually release the lock from the bottom of the steering column. Don't think it's a battery problem as it is less than 2 months old.

I have a 1996 E350 7.3 pstd and it hasn't started since April... Van ran great but had bad bearings in the steering column. I changed out the bearings around the steering stem and it hasn't started since but turns over just fine. The main symptom is the dash loses power when key is rotating from the last run position to the spring back crank position. Basically halfway between run and start the the dash drops power. You can see the problem very well in this video I'm attaching.
I filmed this moths ago so the dash is in disarray and I'm using a screw driver to activate the ignition switch. The screw driver bypasses the key cylinder which I thought was the problem but it's not. Parts I've replaced include new glow plug relay, new ignition switch, alternator rebuilt, 2 brand new batteries, new cps sensor, and also a new pcm. All fuses and relays have been checked and most have been tested, pcm gets power in run position as well. Gotta get this thing figured out it's been sitting for 6 months

I have a F250 towing a Big trailer and the RV folks have told me that while the factory seven prong will supply power to the RV, it would take a days to charge the RV batteries. So...
1) Does the connector not really significantly charge the batteries?
2) Is there a faster way to charge the RV batteries while driving?
3) Would instructions something like I found at How to Charge Two 12 Volt Batteries on an RV Towed by a Ford F-150 | etrailer.com work?
4) Would #3 eventually tax my alternator so badly that I kill it?
5) Would #3 fry the electronics in the trailer?
I'm trying to charge 2 6-volt marine deep charge batteries in series.

I recently bought a 1969 chevy c10 pickup. I have been having problems with the electrical system, the battery consistently going dead despite a new battery and alternator installed by the previous owner. Is there a step-by-step for diagnosis of this problem?

My 2001 F350 Super Duty diesel keeps draining my batteries for some reason, wouldn't crank on Friday. Put my battery charger on for a few hours and it started fine. The rest of the day fired up fine, on Saturday it happened again. Had both batteries charged and load tested today, they are good. Short???

My F250 is acting like the battery is almost dead but its not. I've checked all the grounds I can think of, used jumper cables and clamped right to the body and still nothing. I put my battery charger in place of the battery and my charger almost caught fire! Where are all the ground points at and points to check? It was doing fine then this. I only found 3 ground points on the block and I bypassed all of them and nothing. There are 2 large on the front of the block, I was able to get one loose and "clean" it but not the other. The block to firewall is currently off so I can clean it in the morning.
But it didn't do anything. I can clamp anywhere are get the same results. There are a few threads about this truck and trying to get it back into shape. When it worked, when I turned the key on, gauges worked, RABS, Engine, and Battery light came on, GPs kicked on, etc... now, I get a very faint Batt light, Erie dinging, and not even the stereo now. This truck has been an electrical nightmare since day one. Spent 4 days on just under hood electronics alone. Haven't even moved towards the back. Also, Instead of using a 2/0 AWG wire to the starter, Can I use two 1/0 AWG wires to it instead since they used two separate grounds? It also still has a 2G alt.

Yet again my honda is doing some new. My mid dash lights don't come on at all anymore (even when i start the car), my power drive and winter drive buttons don't work, I can't stop/start on a hill, I have to get 2rpms going to get anywhere, and my battery volts are over 12 when driving.

I have a fuel pump I want to install I want to hook this thing up on a switch inside the cabin to be used as kind of a security device, but I am hoping I can wire it into the ignition as well.... I want the pump to activate when the ignition is turned on but only if the (hidden from view) switch is in the "on" position. Not sure if all this is possible.
I have heard I ought to utilize a relay to avoid voltage loss at the pump. I have never hooked up a relay to anything before although I have heard of them being used. This system is being installed on a 1967 F250.

tonight at 1am: I put the key in and turn the ignition, no start, no click, no dashboard warning lights, no nothing. headlights don't turn on at allearlier in the afternoon - didn't check headlights, but no start, no click, no dashboard warning lights. Sliding 1 key into the ignition gave me a somewhat steady buzzing sound from the car, the kind you get to indicate something electrical is happening (I guess that's what it's for.
I wish I were mechanically inclined.) Sliding the other key into the ignition gave me a much more sporadic buzzing sound. Like metal wasn't making contact, when it should. A few hours previous in the morning - car wasn't starting as described above. Someone pushes the car back from the front so we can make way for another car, to come in and give me a jump. I put the car in neutral, and notice that the dashboard lights and buzzer is on, so on a hunch, I try to start the car in neutral and it starts right up. I drive it to the home driveway, no problem.
2 days ago, I bought the car. A 97 nissan sentra. What it could be? Again, never a clicking sound when starting the car to indicate dead battery. I'm familiar with that.

m having a really difficult time with my '95 7.3. Basically, the PCM is randomly shifting the transmission out and back into 4th with the TC locked. When I say randomly, I mean very randomly: sometimes once in a 100 miles, other times chronically, with no relation to weather, temps, incline, driving conditions, etc.
According to FORScan (using a high quality ODBLink SX USB cable) some sensors are showing a 0.04V dither (this is with the engine off, van immobile): I've already replaced the PCM ($$$) to no avail.
I'm truly lost as to what to try next. I'm about ready to drive this thing into a canyon. FORScan screen shot showing 0.04V spikes

At times when going to start our 1998 Caddy you can turn the key and ..... nothing happens, no clicking ... nothing. Everything else works but it is like you are not even turning the key. Is there a weak spot on these cars?
I am familiar with solenoid/starter issues but this seems a bit different for some reason.

I have a 1992 Cadillac DeVille with 25,000 miles on it. It’s never been driven in the winter and garaged when not being driven.Last year, it was running rough, so I took it to the dealer. They changed the spark plugs and wires. There seemed to be some improvement after that. After about 500 miles, it started to rn rough again. I returned to the dealer who changed the spark plugs again and replaced two of the fuel injectors. Still no improvement. A few hundred miles later, I took it to a local mechanic. He replaced four more fuel injectors and there seemed to be some improvement.After another few hundred miles, the engine started to run rough again, the fuel dropped down from about 20 mpg to 10 mpg, and it stalls at traffic stops or if the brake is applied. After 30 minutes of idling it will use 5 gallons of gas. There are no strange odors or visible leakage.

Recently my check engine light came on on my 98 Cadillac Deville. I went to Autozone and got a free engine diagnostic and was given a printout of a bunch of stuff I did not understand, the technician told me it was just an issue with the light, and it could be fixed with unhooking the black end of my battery for 10m. Just a little bit ago, i popped the hood, and touched the black end of the battery to see how i could unplug it. When i touched it I heard a click and now there is no power to my car. Every time i jiggle the negative end I hear a click from the right side of the engine and nothing happens. I did not even unhook the battery.

04 deville. Trans is stuck in gear. Or seems to be. Car is off. Crank car, starts fine so gear selector/neutral safety switch is ok? Car is running, shifter is in park, take foot off brake amd car moves forward. Since its in gear. Apply brake, shift to neu or rev and car will still move forward. The 2000 caddys had an external neutral safety switch. The 04 cars have an internal switch. If that has an bearing on discussion. Could trans shifter linkage inside trans be messed up? So spool valve in trams is always in gear but shift selector works properly so car can be started?
