Capt Kirk, I am greatly relieved that, Brian, JSeery and Bob C have been able to finally educate you into the correct workings of the third brush generator system. Had some family health issues the last few days and therefore no time to post anything. You could read my posts # 4, 8 and 12 for earlier answers. The correct name for the generator cut out is a REVERSE CURRENT RELAY or RCR. Just another point, depending on your engine idle speed which would be approx. 500 RPM, at that speed the generator would have low voltage output and no output in amps and therefore the cut out contacts would still be open. Engine RPM may have to be 750 or more to enable the generator voltage to be high enough to close the cut out contacts and allow battery charging to be possible. Back in the day when these cars were used every day and most people did not understand the charging requirements one had to take their car to the dealership to have the third brush adjusted down or up to cover summer or winter conditions. The owners handbooks stated this. Good luck with your nice 1936 Ford V8. Regards, Kevin.
