0 - 1023 is GREAT for the throttle signal. My throttle does not make it all the way to either extreme.

It's been a while since I started from the base firmware but I think the defaults work OK with a low voltage pack. The response is a bit slow but that's fine for testing.

It would be great to see the outputs to the IGBTs on a scope to make sure they don't overshoot too badly. Paul has the resistor values dialed in to prevent that .. but it's one thing I'd check. After checking all 6 outputs, it would be time a test with low pack voltage.

You can connect your AC motor and just check the output on your scope with low settings for max battery amps.

Your AC motor will spin with lower voltage, but it takes a certain minimum current so don't be surprised if you're pushing about 1/3 of your rated amps before it starts to spin.
In THEORY there is no difference between Theory and Practice
