2006 C6 Convertible
Added 2 JL subs behind seats...Activated Arc Audio 500.1 amp in pass footwell that had been previously installed on top of Arc 125.4 in stock location...Had issue with previous negative battery terminal, so I replaced pos/neg cable to starter...Added Optima battery D75/25 with top and side terminals for audio system connections...Added curb alert sensor in footwell also...
Installer had to lean on pass side sill to do some of the install, and while leaning there, he bent power seat switch down slightly...When finished, he pushed switch back to get seat in rear position...When i picked up car, I cranked up the tunes and went for a hour ride and listened to music...Parked the car in the garage overnight and the seat switch was stuck in the backward position trying to make the seat go backwards all the time...I heard a clicking on and off the next day which was the seat trying to move further and then the motor has a circuit breaker which would shut off when it overheated...It would cool down and then start the process again...
Question is, intermittently the voltage only charges at 11.2-11.5 while driving and 12-12.5 while idling..It used to charge at 13.8-14.3 normally...When this happens, the ABS and service active handling lights come on...Tested battery and all seems fine...Tested alternator and its charging 13 with 15 volts at battery while idling...Using electrical meter so it doesn't have more than 2 decimals...
Question, could I have damaged module or computer with the seat trying to move consistently and could it be fixed with a reflash??? Would a Tech 2 find the issue??? I am going to snug all nuts on the starter and check ground to block and frame again...Also has problems with FOBS not detected once in a while...Would touching pos/neg cables together off battery reset anything??
Driving me crazy...Help...

 

Anybody?????

 

Are you saying that you are still seeing the low voltages after the seat issue has been corrected? Can't believe you didn't blow the fuse.

Are your headlights dimming in response to bass-heavy muzak?

If so, you may want to start with a "Big Three" install and if the problem still persists, move up to a bigger alternator.

Post on the Audio/Electronics Forum for more info.

 

Yes, still seeing low voltage after fixing seat issue...Recenlty (8 months ago) installed 170 amp billet alternator...Tests fine unless a diode went bad inside???? Windows are slow to go up and down...Definitely more bass in the car, but it should still charge correctly and not throw ABS and SAH lights...They don't make the boig 3 for the C6 yet, supposedly on the way, but like i said, I replaced the OEM battery cables recently...Any other thoughts??? Not sure it is audio install related...Maybe the order cables go on to the solenoid???
HELP!!!
