    MSX 150 Reverse Switch Question

    I am currently working on my MSX 150 to solve an issue I have with it not going over 3400 RPMs. I suspect the System IFB Module.

    While checking a few things, I ohmed out my reverse switch. When the ski is in the Forward position, the switch is closed, putting 12 volts to pin F of the SIFB module.

    In reverse, it opens the switch and takes the voltage off of the SIFB.

    Is this correct? I was looking at the diagrams and they say it is normally open and the magnet pulls it closed when you put it in reverse.

    Thanks for any help....it has me scratching my head.

    Well, if you put it in Reverse does the 3400RPM limit go away?

    mswol767,

    My problem ended up being the SIFB module. The reverse switch worked just fine. Just seems like what I saw in a wiring diagram and what I got for readings were different but it works fine. No problem with reverse switch. Hope you have been able to get yours fixed.
