how do I change out the reverse belt on a CSC converted Harley?

Hi! I have a 2008 Harley softtail that was converted using a CSC trike kit. The reverse belt popped the other day while I was riding- the reverse light is randomly coming on for some weird reason during driving and during charging. While riding I went to honk my horn and the red reverse light was on and it popped the belt. I like learning how to work on my bike myself. Anyone have any resources to start? Also, do I order the belt directly from CSC? A picture of my trike is on my profile (I couldn't find a place here to attach it for you to see what it looks like).

Cissy I don't know anything about your conversion, but it sounds like when you hit the horn button while riding the reverse motor kicked in and popped the belt. Sounds like need to address that issue first. Might be a short somewhere. I would suggest contacting CSC directly they know how the reverse is wired and guide you to a repair. Good Luck
