The fuse is next to the battery on the inner fender.

It is a fuse in a fuse holder not a fusible link.

Tighten The Pule Nut

You’re not supposed to have power on the red wire, or the “pule nut”.

But not having power on the
green wire is a problem.

You have a bad connection from the fuse where it’s suppose to tie into the
green wire.

Physically trace from the output side of the inline fuse to the junction point in the harness, usually located to the right, of the top of the right strut mount.


Happy Racing!
