bill said:sounds to me like your battery is running all the electrics in the car, rather than the alternator. Probably a wiring issue involving the charging system. Need to make sure that all of the grounds are where they should be and that all of the positive leads are properly connected. I would start by disconnecting any amps first, since they seem to be the culprit for this type of problem. If the volts go up, then your amp isnt wired up right and needs to be checked over. Also, make sure the battery is not in a state of discharge. It may have volts, but if it wont hold a charge, the alternator is working overtime to run the car and charge the battery. good luck!
Ahhhhh yes thats what it sounds like, ( battery is running all the electrics in the car, rather than the alternator ) so u think my amps for my system is draning my battery? ok so when i test with them off do i still use the EC82 adaptor? i will need to charge the battery again before i can do so, its dead...very good info. thanks
