Thanks for the replies.I was looking at one of my cables today, and there was a little corrosion on it. Is it true that copper can store electricity? I was told today that they could cause a voltage drop by not releasing the electricity through the cables, as they act like capacitors. Would a washer provide some insulation between the battery post and the cable end? I will be looking into some way to put a coating on them, solder sounds like a good solution. any thoughts on the controller question? Take care, Watt
