If you have a volt meter check to see if there is a drain on the battery when the car is off, you can then pull each fuse to see which circuit is causing the draining. Sounds easy, but I have also seen cases where somone left change (a penny) in the cigarette lighter causing a short cirucit.

SOURCE: got a 1999 ford contour had alternator rebuilt

It still sounds like the alternaror is putting out to many amps and more than 13.5 volts when hooked up but what you could do is to borrow one from someone else and try it if it runs ok then YOU NO THE ANSWER TO THAT

But let me know how you get on . Ron

SOURCE: 99 volkswagen passat starts, then stalls, won't keep idle

I am having a similar problem on a 2003 Volkswagon Passat 1.8L 4 cylinder manual engine. My batter (after 10 years of service) died about a month ago. When the engine is cold and I start it up the engine (if I do not carefully add gas to rev the engine) will idle at around 200 to 400 RPM and then stall. The problem does not occur after the engine has been going for more than about 90 seconds. No check engine light is on. Ideas anyone?

Starts but won't keep running then won't start


Check your Fuel Pressure and if that is good (over 40 psi)

then check your Idle Air Control (IAC) Valve

and seeing that it is a Mid-90's Chevy.. MAF Sensor is going bad.

If you UNPLUG your MAF and see what happens.... MAF is in the Air Intake with a 4 wire...

My 1981 chevy luv diesel keeps leaking oil out of tail shaft I replaced the seal and still leaks idk what the problem is any suggestions.


the shaft may have a groove in it which prevents proper contact with the seal, the rear bearing may have excessive play and the shaft is moving out of contact with the seal, the trans might be overfull or is heating up and creating pressure which the seal cannot hold.

1996 Chevy Beretta won't charge battery


Let the car run for a little while. The battery will read lower after starting because it just pulled power out to start the car. If battery light comes on or the voltage keeps dropping trace all wires and make sure connections are tight. I would think that a 95 model car would have an internal voltage regulator but if not find it and replace it. But be sure to unhook the battery first or you will short the new regulator out too.

Put in a new atl wont charge


If both the alternator and the battery are good, either the alternator isn't turning fast enough (slipping belt or engine idle speed too slow), or you have a wiring problem.

To check your wiring, look for the "1" terminal on the back of the alternator (left side of spade terminal connector). When you turn the ignition key to the run position without starting the engine, the alternator warning light should be at full brightness. If the bulb is burned out, the alternator will not get the excitation current it needs to start up (it goes through the bulb). With the engine running, you should measure 12 Volts at the 1 terminal (this is the excitation terminal).

Another thing to check is whether the battery charge wire is good. If it is corroded inside at the battery clamp end or burned out, you won't get charging even though the alternator appears to be working. If you don't have an ohmmeter, you can make a quick test by adding a new 8 AWG wire between the output terminal and the battery clamp. If the battery now charges, the original wire is bad. If this works, I recommend installing an inline fuse at the alternator end no larger than the largest size used in your electrical system, just in case something happens to the jumper wire. That way you won't burn out your alternator.

The heater/AC issue could very likely be a separate problem, but inadequate power may keep that system from running properly. (Note: low idle speed or belt problems will also be detrimental to AC performance.)

1984 Chevy 3/4 ton truck electrical shutdown on gear shift


I'd start looking for a loose or bad connection in the steering column. I doubt if it's a short or you'd be blowing fuses all over the place. Likely as you move the shift lever it is moving a wire that goes into or out from the ignition switch (on top of the column, under the dash)

Flickering lights on 2001 Chevy tracker


I had similar problems, with dash board lights and headlights flickering, and the problem was a dying alternator. After I changed it, everything got back in normal. Also, a bad alternator eventually will kill your car's battery, too. I hope this will help you.

Battery light stays on


Many possibilities but the alternator is a good place to start, if its plug is loose, then the green relay inside the center console just to the left and slightly in front of the emergency brake will be clicking in connecting and disconnecting the battery( one loud click per time). It will need replacing or simply disconnecting works for the short budget.
