Ford Excursion :: Alternator Gone - Fused Somewhere?
Dec 25, 2013
Coming home tonight I drove the last 10 minutes in total darkness with only enough power apparently to keep fuel pump running. I just replaced the alternator two weeks ago but it seems to have gone again. At the alternator I have 11.3v at idle. There is a two wire plug plus the power cable. One of the wires has constant on power. The other has nothing. It is not switched even though I think it is supposed to be. Is it fused somewhere?

My Ex is missing the label showing the serpentine belt routing diagram. I pulled one off the Autozone website for V10 with AC. It showed that there are 2 idler pulleys (one on the left and right side of the alternator). It also has the tensioner pulley.
I only have a tensioner on the left side of the alternator. The one on the right is missing. There appears to be a threaded hole where a pulley should go. Since I bought this used, I thought the previous owner took it off.
I used the bolt from the old tensioner pulley I replaced for the hardware and put a new pulley on.
I also looked at other V10s on used car lots and none of them had the pulley to the right of the alternator. Should there be one there?

I decided to change out my alternator to a high output. After researching I've decided to go with a DC Power...I'm planning more lights and a power inverter. Any recommendation on which one? I don't care what it cost just don't want to over do it, can too many amps hurt anything? Also, on my previous EX I did the big 3 upgrade. Is it the same on a 2 battery setup?

I have a 2004 Big X. Original alternator was replaced as it only was producing 9 volts under a load. Replacement alternator failed within a day. Did I just get a bad re-manufactured one or would something else cause failure?

Bought a Powermaster 250amp alternator for my '05 V10. Says I need to upgrade my power and ground wires to 4 gauge with fuse on power cable. I don't really run too many accessories other than HID heads and fogs and 2 DVD screens for the boys.
Do do I really need to upgrade my wiring? Can't imagine I'm pulling much more amperage than stock (130amp on my truck).

2005 Excusrion V10 6.8L .. Have the PO720 code ..
Replaced alternator it was bad when tested
Replaced OSS - the voltage on this when running varies in the 1.3 - 1.7 range.
What should the ohm voltage read? What would you try next?

My X keeps needing to be jumped and after being jumped it runs like a top as usual. Took it to Autozone and had them hookup their little portable doohikie and told me the battery is fine but the alternator should be pushing out 14a and it's only pushing 13? Didn't realize 1aI made that big of difference but whatever. I am taking the alternator off in a few minutes and I'm gonna have it bench tested to confirm the output.
Is there a heavier duty alt that I can get? I will be pulling an RV before too long so I'd like to get one that's gonna last. Btw, 2000 excursion limited v10 gas 6.8...

I have a 2000 excursion that stopped charging. The battery light is on . I replaced the alternator but it still will not charge. I have checked all the fuses. Not sure where to go from here...

My turning light needs a bulb replacement (I believe, since when I click to turn right it makes quicker clicking sounds). Does this mean bulb is out or wiring is out?
As for the side light (also on the right) has fallen off and can no longer be screwed back in place as that part has broken off so I will be buying the replacement part/lamp. However, when it fell, the wiring was disconnected so i have lost the bulb and any connection to it. I think I still have the rubber wiring harness, just missing the wiring & bulb.

Picked up a 2000 Explorer XLS for my 16 year old son to drive. It looks and runs great but it needed a new alternator. Long story short, 3 shiny new alternators from AutoZone later, it still acts like it needs a new one. If I check voltage at the alternator, while running, it's never over 12.5V. As I turn on accessories, the voltage drops down to 11.7 and doesn't come back up. When I turn it off, the battery slowly creeps back to 12.5V. The 30 amp fuse is good as is the 175amp fusible link. Shouldn't I have 14+ volts out of a brand alternator?

can I put the alternator from a 96 ford taurus in to a 97 ford taurus? Are any parts interchangeable on different ford taurus's?

I came out from work this afternoon to a dead battery in my '99 Taurus. I saw nothing left turned on. I got a jump and went to Autozone two miles away. By that time there was enough charge to restart the car. My battery checked good, but they said the car had a 4-1/2 amp draw when it was shut off. The alternator still put out over 60 amps when reved up. That's good. Can a bad alternator on a modern car run the battery down? I know the old ones did sometimes, but I thought they "fixed" that aspect of them several years ago.

Had to change the alternator in the 3.0l fwd escape. if some one knows of an easy way to get it out i would love to know. We had to take the manifold cover off right down to the "o" rings as well as what ever we could undo to make a gap between the engine and the fire wall. it took us so long that the repair shop was closed and we had to leave my engine apart overnight with tissue stuffed in the pistons. The one part you know your going to have to get to to fix, and it's almost impossible to get at. It would have been easier to tilt the engine, but we had no hoist, is there an easier way...

My 05 Ford Focus just suddenly died. I had it jumped and moments later it died again. Jumped it again and it died again. Could this be an alternator problem?

I wonder how prevalent this problem is with Ford alternators. Sure looks like it was cracked a long time, like maybe from over-tightening. I was planning on having new bearings installed to hopefully take care of a periodic whine. Already replaced the idler pulleys. As much as I dislike rebuilt alternators, looks like I will be getting one.

My alternator went out last week. I installed a new alternator, battery and serpentine belt. However, the battery is still dying. So far I checked the continuity on the fusible link and it appears to be good. I also checked fuse number 11 which provides power to the voltage regulator. The fuse is not blown. The voltage at the battery while it is running is less than 12 volts and it drops the longer it runs. I also have codes b1318, b1932, c 1226, and c1284.

1997 Explorer belonging to a friend who will show up complaining that his battery is dying. Of course, the problem is intermittent.
So far, tried 2 new alternators, (rebuilds), 3 batteries and several diagnostic sessions which have been inconclusive. What I do know is that when the charging system is not working, I still have full battery voltage on the Y/W and LG/R wires on the small wire plug at the alternator. The path from the alternator output through the megafuse to battery + does seem to be intact. Measures full battery voltage and even tried a test by using a battery booster cable to connect the alternator output directly to battery + when the system was not charging.
No change with this test. Visual inspection of the engine to firewall ground strap and the battery - to rad cradle ground wire seem to be OK. Have not had the opportunity to try the jumper cable trick to verify the alternator case to battery - circuit, (darn intermittent!). There did seem to be something intermittent related to a wiggle test in and around the power distribution fuseblock, but once again, this was inconclusive. I also was able to make the charging system fail, (once) by turning on the headlights and blower motor.Any specific failures that may cause this? Not much left to change or check!

Is there a fusible link from the alternator to the battery? The new alternator that I put on and got tested is not charging the battery. Was wondering if it could be a fusible link but I couldn't find it. Where it is located on a 2000 ranger?
Also, I put a DC volt meter on the negative side of the battery and the positive side of the CHARGING wire that would be connected to the alternator and got the same reading as if I put the meter on the positive of the battery.
Does this mean the fusible link is good?

I have a 2002 ford taurus with a basic 3.0 v6 . The alternator stopped charging the battery.
New alternator
New battery
New pcm
Still nothing, this has been causing me the biggest headache. Alternator is pcm controlled btw...
