Replace the rear blinkers after all Wes black nickel plated. On the blinkers the right was 12 volts and left socket was 5 volts. New PC board in same results. Now voltage is dropping in tail light. It makes no since. So using meter and checking part by part I can't find a break in the system to the rear. Next will be checking grounding points. Any thoughts? All led, load equalizer, all checking to be functioning correctly.
