Its possible you burned a trace in the JB circuit board when your tail fuse blew, but that seems unlikely.

So, even with the blue wire removed, I can still check fuel voltage. I'll do that tonight after work.

All I have left is to connect the headlight, drill and tap holes for rear signals, Mount and wire rear signals, strip and paint side covers, oil and install air filters, get a crankcase vent filter of some sort, get elbows for fuel lines to connect to petcock, fill with gas, and i'm good!

well, whatever works!

if you don't put a fuse inline, a short can kill your battery or start a fire. You said you blew a fuse earlier ... whatever blew that fuse would have done more damage without the fuse.

crowley1027 No voltage to blue wire from jb. Pulled blue wire from plug and touched to positive terminal, light lit up. Working on a switch right now. What can happen if I don't put a fuse inline?

If your blue wire is in the top back position of the JB, yes.

You'd be bypassing good circuitry, and the problem downstream would still prevent the headlight from working.

short story: check for voltage there before rewiring.

Thorn yes, but also add an inline fuse to be safe.
