83 Aspencade coil relay mod question?

Post by snipcod »



I've been going over and bringing a bit of life back to my 83 gl1100. The last few days I've added a few lights and even did the headlight relays, which are a huge improvement! Now I'm into the coils. I've read some material on it, but just can't seem to get it.
I just can't figure out The placement for the 3 wires from the harness and how to put them on my 4 point relay. There is a yellow, blue and a black wire which goes to the resistor.
I put the wire coming off the battery to the 30 pin. After this I'm a bit confused. I thought the black was the hot wire going to the coils so I put it on 87. 85 is grounded to the frame. Now assuming I habe the right wire to the coils, what do I do with the yellow and blue wires? I've tried running them from the harness to the 86 prong, one and two at a time. Which does not seem to work. I'm at a loss.
I think my brain may just be fried, from everything I've been doing. Here's hoping someone here has my magic bullet of an answer.

The Yellow and Blue are the wires that go to the points or spark units. These are grounded by the points or spark units to charge the coil then, when they are 'un-grounded', the coil discharges, giving you a spark at the plug.

So are the yellow and blue consider the hot/ power wires? I found a schematic, and it appears the black and white wire goes from the kill switch to the resistor, assuming it's the proper drawing. I'm trying to visualize wiring it to the relay. Would the black go to 86?

The black is the power (hot) wire which should be switched by the relay. The yellow and blue go to ground via the points (or spark units if you don't have points). If you have condensers, then you should have points and the yellow and blue from the condensers connects to the yellow and blue from the coils. The yellow and blue should not be connected to the relay.
The black from the kill switch should connect to 86. 85 connects to ground. 30 goes to battery positive (via a fuse!). 87 goes to coils.
