r1100 starting problems

[SlvrBllt]

Hello,
This is my first post, so please excuse any blunders I make.

I am currently repairing a 96' 1100R that will be mine to keep for a while if I get it running. It was overheated, and I have repaired the hall sensor, ignition coil, battery and resurfaced the intake valves on the left side. I thought that was all it needed, but I am still not getting any spark. The ignition coil is getting power, but the harness going to the hall sensors is not getting any voltage when the key is on. The plug wires have continuity, and the plugs are new. Any suggestions on where to look next?

Thanks in advance

Does the instrument cluster light up at all? I would try bypassing the sidestand switch first.....it connects underneath the left hand side panel.

Also, I think the early Roadster models had problems with the wiring harness from the ignition key rubbing on the underside of the steering head frame member. Check for damaged wiring underneath the steering head.

Yes the cluster lights up. I just pulled the harness going to the ECU and it is getting power. There is also continuity between the ECU and the hall sensor harness- so that leads me to believe the ECU is shot since the hall sensors are not getting power.

If the sidestand switch was malfunctioning, would the engine turn over at all? It spins, but it doesnt spark.

The sidestand switch will prevent the bike from cranking at all. I'd check it too. They live in a really horrible spot and live a hard life.

Check all of the bike's fuses. Not just by looking at them, use an ohmmeter. K.I.S.S.
