Does anyone know if there is an internal fuse in the CDM1250? And if so, the component number and where it is located?
Thanks!!!!!!!!

F0401 is a 3A 24V SMT fuse that protects against shorts in the control head circuitry. It's located on the bottom side of the circuit board in line with pin 12 of J0401(the control head connector) and C0430.

Thanks, finally found it and it checks good so back to the drawing board.. I have 4 units that will not power up. Was hoping it might be that fuse..
thanks again!

Any chance they where programmed for ignition sense only? Try giving power to pin 10 on the accessory connector and see if they will come alive?
