I am installing a roadmaster trike kit on a 2000 GL 1500. Everything is going great, except the reverse will not work. It engages, starts to pull backwords, and then quits. The bike rolls in reverse very easily, seems like a relay is cutting out. You can keep hitting the switch, and the reverse will keep " bumping" but will not continue. Any suggestions? I need to sort this out before I finish putting the back on the trike. I didn't notice any ground wires on any of the bolts I have removed, just one ground bullet connector for the rear trunk lights, but I may be wrong. Thanks for any and all help.
