Hi and welcome to JustAnswer, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, let's try check and review the basics. Proposed preliminary tries (if have not been done) would be to check the rear's common ground system. Of particular interest would be the black/white wires of the rearend harness and their common tie point / joint connector.

In some instances, it may be necessary (or even if just for test purposes) to hardwire a secondary ground line from the battery's - terminal to the engine, to the frame and to the tail light's, might as well include rear signal lights and the harness' black/white wires and their common tie point / joint connector.

This is an independent site and members of this online community provide information, repair tips, technical assistance as a form of paid Q & A service.
