What is that part back there?

[controlu]

'03 GL1800 with a Champion Trike kit. There is a part rattling around back there. It looks to be aluminum, finned, about four inches square, has heavy wires going to it from the battery. I thought it was a voltage regulator but that's in the alt.

It's the part behind and above the red battery protector. My next question is "How do I get to it?" It is loose and rattling around.

That is the reverse resistor. It is supposed to securely mounted.

Correct. It depends on being securely mounted to the frame in order to drain off some of the heat, so I would avoid using your reverse until it is mounted correctly again.

Champion uses a simple way to mount it. In the screen shot, you'll see a simple black bar that mounts to the battery brackets bolt. Well that didn't come through clear. If you PM me your email address all send you Champions instructions.
