This is out of a 1993 RRC. Please help me figure this out. After spending several hours on my truck trying to diagnosed why it won't start I realized this wire may be the offender. The wire with the black connector and red dot was loose/broken from the end and came right out. Now, this is my question. There is a ring that connects to the chassis, so it is grounded. The wire with the black connector and red dot was connected to another wire with a 12v reading. There was no voltage reading coming out of the other black connector going into the coil? So, what kind of reading was I expected to get at the coil? 12v or simply ground? It does not make any sense to me. If am supposed to get 12v to the coil with this wire why is going to ground? what is the purpose of this design? Thanks.
