Serious Wiring Problems: 2007 Fat Boy
#21
Yes. This is a special construction. DMV has it listed as a 2007 special construction. As i was explaining at the beginning of the thread is that there were a lot of wires cut, spliced, removed, etc. When i got it. Guy just was roping and wiring to get it to run and stay running instead of just finding the problem.
I've gone through the entire loom and rewired everything back to original as well as looking for bare, exposed wires. Replaced or made new plugs for the rear lights. Can't get a spark, but, i think i found the issue. 3 wires on the ECM plug tail look like they shorted together. So I'm getting a new, or a replacement, ECM next.
A friend of mine is certain that the engine is a 97-99 Evo. All the wiring diagrams and parts I've looked up match the same years, so, I'm just going with it until i actually have to open the engine up... which hopefully isn't for a long while.

That bike does not have an ECM, it just has an ignition module.
7 Wires on ignition module:
3 wires from the cam position sensor to ignition module.
Power wire (White/Black) from kill switch branches out to connect to both the ignition module and one post on the coil.
Pink wire from ignition module goes to the other post on the coil.
Violet/White wire from VOES to ignition module.
Ground wire.

Yes I know special construction, he said that first post. Just trying to figure out what he has .
I wonder if he can bypass cam sensor? I would look up manual for the ignition. I believe mine says how to bypass cam sensor.
