Electrical System Issues

[Sherwood4Runner]

This week I've had issues where my car will die while driving, or have trouble starting randomly. I've ruled out the alternator, battery, and post connections. I'm going to check for what sounds like a bad ground on the main 3 ground/positive wires today. Any other ideas I should explore?



UPDATE: When touching the main positive bundle of wires to the positive side of the battery there is no sparking, like no current is going through. Battery reads 12.3v on volt meter. Further thoughts?

Problem solved. After more trouble shooting I took my battery over to get tested and even though it would hold 12v it only had 12 of the original 600 cranking amps. Therein lies the problem. New battery. Moving on.
