Just completed a 12 volt conversion and new wiring harness from Classic Parts ( $150 ). In addition, added turn signal. Head lamps, dome, front parking lamps work along with front turn signal and emergency flasher- only the front. Fuses are ok. Prior to adding the turn signal the rear lights worked and at one point while testing, the rear lamps came on but not any longer. The connections look good. Any ideas? 53 1/2 ton with 235 engine.
Thanks, Scott
