Yep I have power to dashboard. Press brake to start. Unit can be in any gear. Unit runs when I power the starter solenoid direct. Apparently a sensor is not recognizing when brake is depressed. Maybe a switch at the master cylinder?

Yep. All good. Applying power directly to starter solenoid allows unit to start and then operate fine.

550 started and quickly died (infrequent occurrance) In my haste to restart, I believe I stepped on accelerator while turning key. Now starter does not engage. Did I set off some sensor? Unit has 2 relays in fuse box related to starting but I have no way of testing. Thanks for your review
