So im having some really weird issues with my 91 galant gsx. The battery is no longer chargeing will driving and is actually being drained while i drive. I replaced the battery and all of the terminals i also cleaned the ones that i couldn't remove. I took the alternator and had it tested at kragens and they said it was fine the guy tested it twice for me. Im now stuck on what could cause this i relocated the battery to the trunck over a year ago and this is the first time i have had so many issues with the electrical system. Any ideas on what would cause this to happen?
