OHC electrical problem
This isn't anything I have read on here before. The other night, I was out driving and I started noticing that whenever my bass hit, the OHC wasn't staying dim (lights on). Now, i just installed a 130 amp alt, and have no issues with headlights dimming, even with the a/c running and the radio turned up. I notice this from time to time if the truck is at a very low RPM.
