Question about 1986 Chevrolet Cavalier 2 Door
Battery draining completely. Yesterday it drained in TWO HOURS. It's a new battery and we had the battery and alternator checked by a mechanic and they are fine. We are having to disconnect the battery when we are not using the car so that it keeps its charge and we can start the car again. If we don't, we have to get someone to jump start it.***the car make is not on your list and I had to choose a model***
The battery will be fine, the alternator might be draining even if it is charging OK, usually it is the alternator (if you can disconnect all the wires to it and see if it still drains.Otherwise it is a big drain, so what is doing it will be getting warm. It might be unwise to use an ammeter to check as the draw would need to be over the usual 20 amp max for most meters, get back to me with what you find.

Hi David,Take the vehicle for a scan and determine what the fault is so that you can have it attended to soonest. The light means you cannot depend on its operation! Regards John
