Thanx for the pic. Nah I dealt with broken batteries last year. So they are all wrapped with foam this year. Now the issue seems to be the connectors. I use the black plugs like a receiver uses. The wires are breaking right at the back of the connector, which is outside of the boxes and not near any moving parts. I think off road is causing them to move up and down and just break the wires over time. I might have too much extra wiring, but I didn't want to make them short and stretch the wires.

If you look at the plugs there in Danny B's picture my wires break at the back of the plug. But my plugs sit up in the air higher than his. They don't rest on the mud guard.
