Some of us added a Sense wire to help this issue.
also..when you put a load on the motor at idle, like turning the wheels, the engine rpm dips a little. That means the alt turns slower, and produces less power.
Plus your pcm is likely programmed to turn off the alternator field at any rpm under 600.
When I come to a stop or turn the wheel, it drops down to the red. It drops to the line right above the red zone. The lights dim and she starts shaking.
How do I add a sense wire? And where can I get one?
It'* strange because my truck doesn't do that. It worries me since I'm adding some draw to it soon. I just want it to stop
