Another starting problem

What you need to have is 12 volts while cranking and 8 volts when running. 12 volts while running will ruin the coil.

When cranking the 2 blue wires on the one side of the ballast are a bypass and direct 12 volts to the coil. When you leave off the cranking position the brown wire on the other side of the ballast is now the feed and when going through the ballast it reduces the 12 volts to the blue wire that goes to the coil to 8 volts.
