    MF40B Excitation Diode

    I took the wire mold apart and there is no diode. I measured resistance both directions and it was the same, so definitely not there. When I crank it over the oil pressure switch closes and I have 12V at the alternator so it appears they are using the switch to control the excitation on the...
