I have a zone electric golf cart with a JVC radio. After a very bumpy ride the radio started cutting out and then quit working. Since that time, I replaced all the batteries and the charger. Thought I had everything hooked up, all the accessories work, but no radio. Checked all the connections from the wiring harness for continuity. Everything seems to be fine. After putting the golf cart up on a lift, I discovered a wire not hooked up that looked like it went to the battery. The golf cart was made in China so trying to figure out what that wire went to was quite a chore because each time the wires were connected somewhere along the way it went in one color and came out another. After much investigation, it was the constant wire. Now, when I hooked that wire to the positive terminal of the battery, the fuse on the head unit blew right away. I then substituted another head unit and that fuse blew too. I am looking for suggestions on what to do next. I bought a boatload of fuses for this trial and error method for any suggestion that might come my way. Thanks!
