Re: Coil Resistor Wire
There is a resistance wire running to the alternator terminal A that is there to keep the ignition from being permanently on and getting continued power from the alternator. This can be replaced with a low wattage bulb or a diode. Bulb makes a convenient idiot light.
Teamrush has some posts with schematics. Terminal A or 1 on the alternator can use a bulb, 100 ohm resister or diode with stripe towards the alternator connected to a source of key on power. The bulb, resistor or diode prevents it from feeding power back into the ignition circuit even after you turn the key to off. Terminal B is the one that picks up the reference voltage and to which output of the alternator is regulated. Open to debate whether to hook it to the battery or to a part of the harness that gets loaded down.
