I'll check them again. But, these are new cables that I cut to length, crimped and heat shrank myself. I originally did not have the ground cable. After the first couple of poor performance startups, I added the negative thinking that it didn't have enough grounding. Obviously, it didn't help the issue. It's conceivable that I screwed up one of the ends on the positive. I'll swap it out with another and see if anything changes.
