No. It didn't have issues with the entire electrical system, just the ignition. Bike had full power, no spark.
Are you asking if the Ignition Module on my bike is located on the steering neck?
Yes.

Well I rode several hundred miles, on multiple rides with a perfect running engine on the used test module.
The Crane HI4 8-3100 just arrived. I'll be splicing my old module's wires onto the new module instead of buying a $50 conversion harness.
I'll be installing this module real soon and will report back on anything I notice that's different than using a stock module.
Many Thanks to John T.

It's well diagrammed, and electronics is my forte'.
I just wish it came with a "pigtail" with the connector to make it really simple. May see if it's available other than in the "harness adapter".
Thanks for presetting it for me.

I spoke too soon. Seems the diagrams show the color codes of the wires coming out of the connector in the harness, but not the color code applications of the wires coming out of the module going into the connector. Those wires are obviously uniquely defined because they are different colors than the wires in the harness.
Going to have to dig around to see if somewhere there's a diagram associated with the modules wire color codes and their connecting points.
The 7 pin connector is common on later bikes. But where the issue comes in is the connecting point of those color coded wires directly out of the module . The harness re-addresses the module's wiring into the appropriate groupings, converting the color codes correctly to match the bikes connections. Without the harness you can't match it up.
It might be better to have the harness. p/n 32408-90. My local dealer had some last week when I checked on an OEM stock replacement ignition module.
What's another $50 bucks.
In case someone can look at a wiring diagram on a later model using the 7 pin plug, the wires coming out of the module going into the 7 pin connector are color coded:
Red
Black
Purple
Blue
Black/White
Red/White
Green/White
These may be the "new" colors and you can identify which are which for me.
1 connection is to the VOES.
1 connection is to the + side of the coil.
1 connection is to the - side of the coil.
1 is ground
3 are to the sensor plate and need to match correctly with
Black & White Wire
Red wire
Green wire
It would be so simple if the 7 pin connector on later bikes was the same color code as the modules wires.
Sorry I'm rambling. It's late after work and I'm barely awake.

i put a new harness on my 85 when the module went out. if the module ever goes out again it's a 15 minute job to change it out. unplug it and replace it.

It does make the most sense.

Hey Brother, when testing the module, should I disconnect the ground lead wire from the ignition module connected to the ground side of the coil post when cranking it over to check for ground flashing? Or do I leave it connected to the coil ground post for testing? Should I connect the negative end of the test light directly to the lead module ground wire (disconnected from the coil post) to test (ground lead wire from module) for flashing ground to the module when cranking it over? Should the positive side of the test light be connected to the positive battery post or the positive post on the coil to properly perform this test?

Your attention to this matter is greatly appreciated.
