I purchased a Rotary Performance ECU a couple of years ago for my 93 R1 and it has served me well. Yesterday I lost a number of electrical accessories and I wanted to see if anyone thought it was an ECU issue.

I believe I checked all the fuses (under dash and 3 under hood locations).

Not working:
power windows
interior fan
wipers
wiper sprayer
ABS warning light on
Exhaust Temp warning light on
starter solenoid (no click when trying to start but car push starts and runs fine)
Low boost (but I have a profec B and it has no power either so I presume that's the reason for the low boost). The profec is powered from the sunroof fuse which I don't have as it is an R1.

Working:
Pretty much everything else
headlights
emergency flashers
rear defroster
power mirrors
door locks
interior lights
dash lights
radio
power antenna

If the car runs after push starting, then the ECU is fine. Did you try jump starting the car?

I can push start it, the solenoid is not getting power. The battery is fully charged. All these things happened at the same time. Does the clutch switch which overrides the starter need power to work? If so that's probably why I can't get the starter to click.

The clutch swtich shouldn't need power to work (i think) It's just a ground/ not ground depending on the position of the pedal. So it shouldn't need power.
