Is There An Electrician In The House?

[Tom Wesenberg]

This is a good example of where being there would sure help to diagnose the problem. Are the terminals soldered to the wires? Are all connections clean and tight? Is the wire of proper guage?

Trying another battery is a good idea for peace of mind, but I still wonder if the generator is putting out more than the indicated 4 amps? Where is the adjustable brush set? Moving it up lowers the output.
