    Mine, too. Replaced (new) the alternator, the voltage regulator, and the battery. If I'm doing daytime driving, it's OK. I don't like to use accessories - no radio, wipers when needed.. nighttime driving necessitates using headlights, which drain the battery and thus, renders the car useless until I charge the battery again.

    This is either a problem with internal wiring (not real fun) or one of the things I recently bought and installed.

    I wonder if anyone has tried to chase down the wiring problem, and if so... what did you come across?

    Thanks in advance.

The advantage of having this tool will speak for itself, when you have a low battery boast that is having a hard time turning over your engine, esp. on cold mornings:

I had the same problem with a 99 Bonneville- After replacing 4 batteries and checking out the alternator--the CURE was in the battery cables! They stack two cables on top of each other on the plus side terminal battery. The conductivity between the cables was the trouble. MY mechanic cut off the terminals and put on two cheap terminals which stack like the originals and Voila' no more problem!

The battery won't stay charged

Hi it is possible that you Alternator is faulty,if you have access to a VoltMeter ,check the battery voltage in the morning before you try to start it you should have around 12.7 volts for a charged battery if not fully charge your battery again and check the voltage with your car running you should have around 14 volts with the engine reving at 1500 revs.ifyou get around 12 volts then your lights are taking more power from the battery than the Alternator can replace.You could also get your local garage to Drop Test your battery to see if any of the Cells are faulty

My mom's 1999 Intrigue all of the sudden won't start. I drove it Sunday to church and back. I went back out about 30 mins. later and it was dead. No turn over, no power locks or key remote...

Just pull the starter off and take it to autozone to have them test it also. The solenoid should stop the car from having power though, it will make it not start. Sounds like you might have a wire off, did you check the fuses you found in the engine compartment? Check the IGNITION fuses again, or your ignition it's self might be out. Check your wires at the starter and check those fuses. You could also check for power at the starter with a test light, etc. Give this link a read and fallow these steps hopefully to find your problem. Let me know if you need more assistance.

Replaced battery. still would not start. Cleaned treminal of all corrision. cranked fine. however 1 day later would not start. jump started . drove a couple of miles but when I turned on lights, engine...

Sounds like a bad alternator. Drained your battery and when you turned on the lights it took all the power left in your battery. When you drain a battery down that far, they are real hard to jump, and coupled with the alternator, the car is not producing enough current to start and stay running.

I would take the alternator off and take it to oyur local auto parts store to be tested. If bad, replace it and charge the battery fully before starting. Then check voltage at battery with motor running. Should be 13.2 -14 Volts DC. If not, you may have a bad battery cable or blown fusible link. (especially that if the alternator tests good).....Mike
