cutout/voltage regulator for '29 Hudson

Guys,



I'm trying to find a voltage regulator that is made to look like the old fashioned cutouts on early 6V generators. I understand that a fellow named Paul Wessenburg in Minneapolis makes them, but I don't know how to contact him. Bert's Model "A" Center in Denver carried them, but when I called them, they said they couldn't get them anymore. I want to get one for my '29 Hudson SuperSix Victoria. Bert's catalog description said "cutout with voltage regulator inside it, looks like a cutout, but functions as a voltage regulator. Just set the amperage up high, and this will regulate the voltage, charging the battery only as needed without overcharging. Saves batteries by eliminating overcharging, etc." Since our old 3-brush generators only have one wire, more modern regulators won't work, but apparently, Wessenburg figured out a way around the problem. Any help you could give me would be appreciated. Please email me at "scraig10@juno.com".



Thanks,

Bill Craig (hudvic29)

    I doubt that there is any type of regulator that will work without cutting in to the field wire to alter the voltage supplied to the field winding. I modified my '29 Hudson with a rheostat connected to the winding side of the field circuit, so I could manually regulate the current. The fuse on the '29 generator is connected one side to the winding, and the other end is grounded. The wire from the winding side of the fuse I connected to the rheostat, and other side of the rheostat is grounded. With the third brush advance to maximum you can regulate the resistance in the field, which alters the charge rate. So when driving during the day, i have it around 5 amps, and when driving it at night, I can wind the rheostat around to increase the charge to 5 amps with the hadlamps on, which ensures good lights. A heater rheostat does the job fine.

    Geoff,

    Thanks for the reply! I've been fighting a leaky waterpump and also resurrecting the vacuum tank, so I haven't been on the forum to check on answers to my query. The vacuum tank now works as it should, and I have the rear gland nut packing replaced with two modern seals, so that leak is solved. Now, the front nut has started leaking!

    I thought the advertisement was too good to be true for a voltage regulator fitting into the cutout space, since what little I understand of the generators' operation says that you have to have some device to vary the field strength in order to vary the output amperage. I couldn't see how that could be accomplished with only one wire. But since you did it with a variable resistor, maybe he had some way of automating it? Perhaps his regulator ran those same connections you used thru his device? I still don't know how it would get the battery condition info it would need to regulate charging rates. Well, I guess it would get that from the existing wire, but then it would have to connect thru the fuse lead like you did and monitor the battery condition to regulate what charging rate would be proper. Would you mind emailing me so we could discuss this in more detail? I think you are one of the fellows Pete Welzbacker told me to contact in N.Z., because you were '29 experts. You must be Geoff Clark.

    I would appreciate your help. I'd also like to discuss how the waterpump comes off and if the timing chain/sprockets have to be disturbed.

    Hudsonly,
