Was the power input ever wired up backwards? That will fry them.
We had one wired backwards, and it blew, but the lights still worked as if there was no problem, but there was no motor output.
Mike Copioli said they were updating the firmware so the light sequence changes when this failure happens, not sure when this hits, or hit production units.
I don't know if there is a way to test for this condition. Send an email to
support@crosstheroadelectronics.com Mike was very responsive.
