  • HRD Fromel Mod

    I recently installed the Fromel supreme mod kit in my HRD and I'm having problems. I was extremely careful to mark all wires harnesses that plug into the PCB, but after hooking it all back up I have no power to the amp. I checked the fuse (good) I took my multimeter and checked filter caps and nothing. The only reading I got was at the power cord connection at the power switch. Any suggestions?

    Put your meter leads on the line & neutral legs of the power cord.
    Set your meter to read ohms, low scale.
    Flip the power switch.
    If the primary wiring is correct you will read the transformer winding.
    That will prove out the wiring, the switch, the fuse, the thermistor & the primary winding.
    If that proves out then you have a secondary problem.

      UNPLUG IT FROM THE WALL FIRST!!!


      I will bet my lunch money you have a wire wrong in the primary connections. The schematic I think is very clear what wires go on what posts.
