I have a 1987 Honda Accord LX that is draining it's battery. I put a new ground wire on it. Battery tested good. Removed battery cable from running car and it did not die so we are thinking it's not the alternator. Any advice?

Thanks

 

As a temp solution, get a battery cut off ****/terminal at the a-parts store
about $5. When I work on my car, the first instruction says "disconnect the ground"..... LOL so I do...quickly with no wrench required.

When you park it with a charged battery, unscrew the **** a couple times.
If the battery still drains, you need a battery.-Bob
