How do you test the micro switch on the mfi??

[steve meltzer]

I AM SUSPICIOUS OF THE MICRO SWITCH THAT ALLOWS MORE FUEL UNDER CERTAIN CIRCUMSTANCES. I WANT TO TEST THE SWITCH AND DON'T KNOW WHERE TO PLACE THE VOM PROBES AND WHAT OTHER PARAMETERS NEED TO BE MET TO GET AN ACCURATE IDEA OF THE HEALTH OF THAT SWITCH. Parts ANY HELP WOULD BE APPRECIATED. THANK YOU, steve
