December 22, 2005I have added some power sucking lights and audio equipment to my truck. At idle my headlights and driving lights dim. What is my best upgrade to fix this and why? I do not need them to run with the engine off.
Here is how I understand it to work:
Dual batteries are more for allowing things to run with the engine off and still having a battery to start the truck with. But I was also told that this would solve the dimming light problem.
A high output alt would give me plenty of juice at idle.
So what are your $.2? any links to good items?
