This set-up is bustin' my chops! noTurn signals front or back. Have a diagram from Kirkham and era. Slight wiring differences, and Ive tried both with no joy.
Both show flasher unit marked L, P, & B. I've tried 2 flashers, one just arrived today from Moss motors, and both are marked L, P, and X. Kirkham dia shows L as the dash light, ERA shows L as going to the relay box, and P going to the dash lite. Neither way works for me. I hear a relay click when I select L or R on the turn sig switch, but no lights, I don't know whats going on in the isolation box, but thats where I'm losing power to the bulbs.
Yes I've searched, but found nothing helpful.
Anyone have a diagram of the inside of the box ?
