I hear what you're saying Lang. My dad had some pearls of wisdom he used to quote when appropriate.
One was, 'Two heads are better than one, even if they're wooden heads',
Another was,'Even the village idiot knows something you don't!'.

Good earthing is a must U.G. That's something that I will look at but I'm usually careful to get good electrical connections even to the extent of running above earth return wires where i'm not sure.
With a 6 Jolt system you can't afford to lose any.
