Re: Troubleshooting motor controllers
From everything you've said, it sounds like everything is correctly hooked up electrically - ie nothing "shook loose" on that side of things.
Use a multimeter and make sure that the GND and +5V pins for the PWM wires you're using are reading the correct voltage. If not, your sidecar might be busted.
Do you have access to an oscilloscope? It would be nice to scope the PWM signal coming out of the digital sidecar and make sure it looks correct. If not, you can try using a multimeter set to AC Voltage. It's not perfect, but if there's no signal, you'll read 0V, and if there is one you should read a voltage.
Have you checked that all of the PWM wires are seated correctly? Sometimes they can be loose, and riding around in the back of a truck on a long bumpy drive might be enough to shake them just loose enough from the Victors that you don't get a signal anymore. It would be odd for this to happen to all of them at once, though.
Are you sure the code hasn't changed?
