Good morning folks. I am trying to figure out a voltage problem with my coil. Motor is a 1983 3.7/470. I was reading the resistance to the coil I have twins. The good motor is within spec, 1 to 2 ohms. The bad one is 4 ohms. I have the 1 wire alternator. The resistance wire kit is 84-94227A2. The diagram on page 3E-13 of service manual # 3 shows 3 wires at the choke.
1. A stainless steel core purple wire.
2. A copper core purple wire.
3. A black wire.
On my motor there are only 2 wires at the electric choke. A red wire and a purple wire. I tried cutting out the purple wire and putting the new resistor wire in it's place but the existing purple wire is what supplies 12.5 volts to the coil so no go.
Any advice would be greatly appreciated. I dont think it was jacked with by the po because i have twins and the second one is the same way. Did this motor come with a coil with the resistor built into it also?
Thank you.
