My Club Car Cart electrical issue: Blue wire mystery in fuse box

I’ve got a Club Car electric golf cart, and it’s just stopped working out of the blue. I was tinkering with the fuse box, added a voltage reducer, and then noticed this loose blue wire. I’m not sure where it’s supposed to go. The cart’s a 1994 Trans-sender, and the wiring diagrams I’ve found don’t seem to help. Has anyone faced something similar? Any advice would be nice.


I had a similar problem with my Club Car golf cart a while back. It turned out the issue was related to the turn signals. In my cart, the blue wire was meant for an add-on factory turn signal switch. Once I figured out its purpose and connected it properly, everything started working again.
