fourfords, Im not sure but Karls ford might be a right hand drive car being in NZ. So therefore your drivers side up/down instruction on the third brush would be arse about would it not ? The ford owners handbook and service manuals always say to adjust the third brush with rotation of gen to increase output and against rotation to decrease charge rate. Also back in the day and even today most people don't own a proper automotive generator test set with a quality amp gauge and voltmeter to connect to the generator to set the third brush. Nor do they have access to an auto electrical repair shop with a test bench. The best they can do is use the dash ammeter which only gives an approximate reading but is usually good enough. Also the 32 and 33 ford V8 generators had no cooling openings in the front or back of the generator and no cast in fan blades on the gen pulley so a maximum charge rate of 10 amps is all they can safely charge. The 34 ford V8 was the first year of the air cooled generators which had a safe output of 14 amps. They will do more amps but 14amps is a SAFE maximum with no overheating. Regards, Kevin.
