I installed a treats 12v light coil and universal regulator on my puch maxi.
Both yellow and green from coil go into yellow on regulator that is bolted to frame. Red from regulator goes to headlight, tail and brake lights.
Tail and brake lights are 2.5 watt and 1.5 watt ac/dc g4 LED bulbs. I wanted to run a 55w halogen in the headlight but nothing in the tail comes on even if i rev the engine. I reconnected the old 6v 21 watt headlight buld to test and still nothing comes on in the tail.
I thought maybe i had a weak ground at the tail so i ran a wire out side the bike to the place where the head was grounded to check, and that made no difference.
Am i missing something here? Why is the headlight sucking all my power and leaving nothing for the tail lights?
