Lost all electrical power when i turned on the headlights this morning...

Recommended Posts

Started the car this morning and when I turned the lights on everything died as if there was no battery in the car or anything. So I disconnected the battery, pulled the ignition switch and put another in, reconnected battery and still nothing. going to return the switch so it seems thats not the culprit.... Anyone know where else to look? if not Im going to have to trailer the car back to the shop that works on it by my parents house 45 min away...

 

Thanks in advance,

Matt

Dying after turning on headlights suggests charging system. But no power at all now suggests dead battery or bad connections. Have you eliminated those possibilities?

 

going to take the battery to bench test it either tonight or tomorrow, but I could get the motor to turn over by jumping it at the solenoid. It would immediately die again as soon as I the screwdriver away that was making the connection though.

 

** The bad connections is a MAJOR possibility, my wiring harness is pretty sad looking. Wanting to upgrade to a modern harness, but i don't have the funds nor the place to do the swap since the cars sitting in the parking lot at my apt at college right now.

I have a couple of suggestions to check. If you have jumper cables, jump from the minus battery terminal to the chassis somewhere. There is a good chance the ground wire from the engine to the chassis (on the back of the motor) is bad.

 

If you have a good battery, the problem is not with the charging system. A car will start and run for a long time with no charging.

 

I would also clean the teminals on the battery with a wire brush. Too many times I have seen these get dirty and not make connection. Even though you think they are connected, if the terminal is oxidized, you will not get any voltage out of it.

 

Do you have a voltmeter? You can buy them cheap enough and it will give you a real good indication for where the problem is. If you do not know how to use it and what to look for, you can ask us.

I know nothing about electronics, which is something I really need to start learning. But my mechanic told me to use a wire with alligator clips to connect the positive side of the battery to the positive side of the ignition coil. With this method and jumping it at the solenoid i was able to get the car running to drive it to his shop 40 miles away instead of paying $220 for a tow. Im pretty sure he knows what the problem is because Ive gone through this before so ill be sure to have him explain it so I can fix it myself net time.
