View Full Version : lighting coil, how dose it work?

The coil is not working due to no negative supply from the ecu. I have 12v at the coil and 6v across it. Which is the violet/blk wire (no.28) from the ecu to negative side of the coil. What turns on the headlight relay?

I only have a stop/start switch and the key. The dash, light control have been unpluged.
