Hello everyone new to the forum and am enjoying the information I have found so far. I recently purchased a 1952 Ford 8n and it seems to have a charging problem. The tractor still has the original ( I believe) generator on it , but it has a 12 volt battery and the polarity has been changed to negative ground. the generator is putting out 14 volts at idle and that increases as the RPMs are increased. I get the same voltage reading at the ARM connection on the regulator but only 8 volts at the BATT connection and nothing at the FLD connection. I assume the regulator is bad but am unable to find a 12 volt regulator with the 3 posts. Any help would be greatly appreciated !
