    My friend has a fisher v plow with the fleet flex. he said when he went to plug the plow in he heard the truck module click and now the controller won,t light up. I checked all the powers and grounds, I have power into the module on the truck but not on the output wire.
    Sound like something familiar to anyone?
    Thank For your help

    Assuming it's a three port module, there's two ten amp fuses in a common holder which are broken out of the lighting harness near where it plugs into positions B and C on the isolation module. One of them is the controller fuse. I'd start there.

    I checked and got a schematic off fishers site. 12 volts from that fuse into the module nothing coming out. I hate the Fleet Flex, why leave a module out in the weather.

    Well, they're all that way, not just Fleet-Flex. Technically it's all weather-pack connectors, and under the hood of the truck isn't exactly "out in the weather".

    Do you have 12V at the red wire coming out of the control harness near the controller plug?

    no and the schematic show it comes from the module. Now what caused the module to go bad

    That wire should be connected to a key switched 12V source. I wouldn't condemn the module yet. They go bad less than once in a blue moon... like once in every ten blue moons.
