Ford - Mustang :: 2012 V6 Won't Start - Battery And Alternator Are Fine
Jul 1, 2014
So 3 times in the last 2 days, my car has needed a jump start. Took it to pepboys and they told me to replace the battery, a new battery later, my car wouldn't start again and I needed to get it jump started again. Took it back to pepboys, they say everything checks out fine including the battery and the alternator and that it should work fine. This happens to be exactly what they said the last time.
The car is a 2012 Ford Mustang V6 convertible.

I have a a 2003 or 2004 Nissan Pathfinder (can't remember which at the moment). For the past few months, it's been having the same problem. One morning, I'll go out to start the car and the radio will have stopped working, but everything else is fine. A few days later, however, the car won't start in the morning. I'll jump it off, and the car and radio will be fine again for a few weeks. This doesn't last for long though.
Eventually, the radio will go out, and a few days later the car won't start again. I took it to my local mechanic and they tested the alternator/battery/ starter and said they were all fine, and that the battery cables just needed to be cleaned. After the cleanup, the car and radio worked fine for a few weeks...but sure enough, a few days ago, the radio went out. This morning I had to jump my car off again. What the real problem is? I'm taking it to the shop again today, but what else it could be...

A cold engine crank will turnover and start normally. But stop to run and errand or grab lunch...and the warm 302 2 barrel engine will turn over very sluggishly, lke the battery is dying. If you wait until the engine is cool, an easy start is assured but that takes hours! A local repair shop has rebuilt the carb, the battery & cables are new, and the starter works fine when engine is cold. My local repair shop is out of suggestions. It seems to work a little to hold the gas pedal down on the floor for a warm engine start....but engine still turns over sluggishly when trying to start when warm. Now If I drive it.....I just drive it around town a bit then back home ...unless I stay several hours somewhere while the engine cools....but that's not fun. It is a convertible, fun to drive...and this problem needs to be solved.

What is wrong with her car. It is an 05 subaru outback 3.0. She bought it 4 months ago. A week ago the battery died at red light. It tested bad and was replaced. Then yesterday it died at stop sign. Jumped it and died in 5 seconds. Before dying, car would not rev. Jumped it leaving cables on for 5 minutes since battery was almost drained. She made it half mile back to office and coasted into lot. Battery tested good but drained and was fully charged. Alternator tested 7 times to be certain. We bought a 10A multimeter (our town has no 20A).
Tested for parasitic drain. No results. We took Alternator off and tested a couple more times. We took out non essential fuses to be safe. Nothing was left running. There was a phone charger that has been plugged in for the whole four months. She took it out for good measure. Starter tested good. 3 people said battery cables are good. They appear to be non corroded and tight imo as well. They checked fuel pump. All was well.
She wants to go on vacation for the 4th but is scared to try. Mechanic friend said wait until it happens again, go to o reileys and demand them replace the battery as it has to be bad even if testing good. I'm not sure of this is the correct approach, but what else is there? One online mechanic said a voltage test on electrical system is next step but only a few select mechanics even know how to do it such as one that specializes in electrical wiring or something like that.

We've got a 2012 F550 6.7 with 138k. It recently got a battery light. The batteries are right around 12 volts with the truck running or off. I also tested the output on the alternator and its not charging. I put a new alternator in it and still no charge. All the connections are tight and clean. The batteries load test ok. Where to look next?

I went to start my 2006 F350 6.0 this morning. 20 degrees outside. It nearly turned over, then it appeared that the batteries would not support another start - a slowing of the pre-engine start revving....
So I let it sit a while, now it won't start at all. When I try to start it, the dashboard flashes, clicking sounds occur and even after pulling out the keys, the needles on the gauges shake for a few seconds.
Is this more a battery issue or an alternator issue?

Over last two years have replaced a few alternators and (3?) batteries in my 2000 Solara SLE with 150,000 miles. However, In last three months I have had three additional alternators. Car wouldn't start, had it towed, and a mechanic put in new alternator and battery. Happens again, car won't start (now own a jump charger!), and the same mechanic puts in new alternator. Happens again and Mechanic #1 says he has checked it and its fine. I then go to my regular mechanic... Says its the alternator which is bad (when you put the AC and Radio on, it appears to charge for a while, but if you leave it running it will stop charging and then after a while it will go to overcharging and undercharging. I noticed when driving on highway my lights will brighten and dim).
He sends me back to the first mechanic because the alternator is bad. They put in a new alternator. I take it back to Mechanic #2 my regular mechanic to test it so I don't get stuck. He says its still doing the same thing. I tell him I will pay to have him put in the new alternator and he can own the warranty.... He sends me to a car electrical specialist. After having my car for 3 days the car electrical specialist just called and said in 30 years he has never given up but he has now. May or may not be related: My check engine light was coming on and I had mechanic put in new oxygen sensors. I also have intermittant traction light and ABS light coming on and the check engine light will sometimes come on too. My dash board feels like Christmas...

My wife's 2007 Buick Lucerne wouldn't start the other day after sitting maybe 20 minutes with the headlights on. She had to call AAA for a jump start. It starts fine now. I took it to an autoparts store, the battery shows 90% life left. Brought it home, charged in 10 minutes using my car charger. My question is, what could cause the car not to start so easily? I am skeptical the battery was the culprit. How can I check the alternator, etc? Any other thoughts?

My SC430 has been acting weird for a couple months now. I let it set for a month or so and the battery died. I charged it up and it was fine. Now its not starting again. It cranks just fine and all of the electronics seem to be working. I've tried all 3 of my keys. The first time It did this I unhooked the battery and charged it, put it back in and it started and ran fine for a couple weeks. Last week it did it again, took the battery out charged it and it ran for one day. Now its just cranking again. The battery is only a year old, but I think I am going to go ahead and get a new one and see if that works.

My battery went dead so I replaced with new. This did not fix the problem so I replaced the alternator. It's working now but the battery light stays on. I think I still have a problem.

2002 Ford Focus SE with 130k miles on it. For the past 4 months the battery light flashes randomly while driving. The flashing and frequency of flashing doesn't seem related to anything I can tell including temperature, length of time the car is running, speed or any variable. Seems like it should be an alternator, but that was replaced less than an year ago and it also has a new battery. The alternator always checks out fine at the mechanic and it will never flash for the mechanic. It went 1 month with no flashing and suddenly it will now flash maybe 20 times in a 5 mile drive. Yesterday it just died at a stoplight with no warning, but then after shutting everything off it started just fine and the battery light didn't turn on for the 2 miles to home.

2009 Hyundai Accent w/~90k miles
The other day my car failed, showing all the signs of a bad alternator (battery light on, lights dimming/flickering, etc.).Had a mechanic look at it and it was definitely the alternator - the bracket had even broken - as well as the battery.After replacing, though, it still has a problem with charging the battery, at least on initial start.Basically, when you start the car, the battery light comes on immediately. Hit the accelerator or drive 15-20 feet and the battery light goes out and the alternator starts charging again.
The mechanic thinks it is a wiring problem and said that would cost 800+ to fix. He suggested I just live with it. Does his diagnosis seem correct? Are there other things I should look at and/or test?

This 2005 LeSabre with a 3.8 v-6 ran fine but had a marginal battery. Then the key got left on overnight leaving the battery totally dead. After jumping the battery and letting it charge, the engine cranked fine but refused to start. Haven't had a chance to check for fuel or spark. Why would a dead battery trigger this no start condition?

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.

I have a new 2012 mustang GT with just under 5000 miles (no brembo package). For the first 3-5 stops, the passenger front brake squeals loudly right before coming to a stop, then goes away for a while. Intermittently, while the car is warm, it will squeal very loudly at low speeds when coming to a stop (10mph). The car does not pull and the stopping power doesn't seem to be affected. I've taken it to the dealership, they say they can't reproduce the sound. They resurfaced the rotor and claim that nothing is wrong with the brakes, but the resurfacing did nothing to fix the problem.

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.

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?

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...
