Picture of Harlan RPM switch circuit

Hi. My harlan RPM switch quit working. It looks like a resistor fell off but there could also be something else wrong with it. Does anyone have a picture of the RPM switch circuits?

I just happened to have my Harlen RPM switch next to my desk and my phone so here you go.

I can get some better/clearer pics tomorrow if you want. Camera phone FTL.

Thanks. Mine looks the same; except for blue buttons

. Maybe the micro controller went out. I will have to do some testing.

On mine, it says HARLAN '00 RPM V3.1 2003 but in the photo, it's covered up by the plastic end cap. Maybe there are different versions.

Have you tried redoing all the settings? Maybe that might fix it.
