I have a 40-year-old car. For the last six months, since I installed a new stereo and amplifiers, the car was quiet. All was good.
added LED bulbs through the car.
Still all quiet.
I found I was having a voltage drop under the dash and went through my harness, looking for bad connections. Found a few.
Including the ground wire at the battery connector terminal was loose.
I drove and found major noise and Alternator whine rpm affected. (voltage back up to 13.8-14.2)
More complex:
Major noise with key on and engine not running.
I put a separate power and ground to the head and amps. And it was quiet.
I turn the key on and it scrams noise. Car not running just in on position.
I started disconnecting everything from the coil back looking for an ignition point being the problem. Made no difference.
I installed New 12Ft RCA triple shielded from Head to Amps. No Fix.
Moved the RC Amp Feed to the other side of the Car. No Fix.
I found your threads on noise here and added the ground around the Rca's and attached to a solid OEM ground point by the radio.
Didn’t fix.
I tried adding PAC noise filters NSI-1's Didn’t Fix
Added snap around the wire chokes on the Posi wire Didn’t fix.
Suggestions, please.
Thank you in. advance
