Sorry for the delay but was in same spot for several weeks and had trouble finding a compatable unit. Finally was able to install a compatable unit (120-105452) a couple of days ago and it still will not charge from chassie battery. Was told that there should be a timer relay that will activate the coil. Was told the relay would be in under dash connected to the emergency start switch. Problem is the wires from switch run from switch to plastic tube that runs under the unit to coil area and there appears to be no relay.
Any ideas?
