I have a 1936 Deluxe touring Fordor 85hp: The generator puts out 6.5v at idle, 5.9v with headlights on. The amp gauge jumps to negative with lights or radio on. Is there an adjustment to the 3rd brush or voltage regulator? I also found the terminal studs on the generator are stripped so the connections are finger tight at best. Another problem: after 25-30 minutes of hwy driving, 50-55mph, starts losing power and doesn't want to run over 35-40. Plugs looked ok, cleaned them and ordered new set. Compression is 75 across the board. Thanks Guys. Tim

First fix the connection and check all others for cleanliness and tightness. Once this is done you can check and adjust the third brush for voltage (7.5 Volts). Remove the band from the rear of the generator. Inside you will see this: http://s191.photobucket.com/albums/z73/lightflyer1/1935%20Ford/?action=view¤t=1935Generatorbrush.jpg The silver part with the screw is the third brush. Moving it to the passenger side will lower the voltage and to the drivers side raise the voltage. I have read that if you do not drive with the lights on much set it with the lights off and if you do set it with the lights on.

My generator does not have the voltage cut-out on top and no band at the rear, just narrow slots at the rear.

Your generator appears to be Not 36 maybe later like 39-48 style. You should have a voltage regulator somewhere since your generator has only two brushes and is not adjustable. The voltage regulator may need adjustment to increase the output of your generator.

Thanks 40 Coupe. Regulator is on the firewall, left side. How do I adjust it?

More often than not, trying to adjust a voltage regulator results in having to replace it. There are three relays in the regulator. Looking at it with the cover off, the one on the left controls voltage, and is adjusted by bending the adjustment arm up to increase, and down to decrease. The arm is on the left side of the relay toward the contacts, and controls spring pressure. If you are unsure what to look for, I'll post a photo. After adjusting, replace the cover and retest the system voltage, as the set voltage will drop after the cover is in place. Before attempting to adjust the regulator, clean the contacts thoroughly by sliding a piece of clean paper between the contacts. Adjusting the current relay at the center takes a meter capable of 50 amps capacity.

Tim, take your generator and regulator to a shop that rebuild generators, like Vintage Voltage in Downers Grove and have both of them checked out. Incorrect adjustment of the voltage regulator can cause the generator to throw solder or damage the battery.

Thanks Guys, I think I'll take your advice Tom and take the parts to Vintage Voltage.
