Gene Harper Solid State Regulators

[DEEBS47Chief1991]

I recently contacted Gene Harper and unfortunately he no longer sells his solid state regulators. Does anyone know of another resource? It was nice how he installed the units inside a stock looking cutout or old metal regulator shell. Very clever. I could possibly hide a solid state 6 volt regulator under the Indian generator but I'm not sure of the amperage requirements of such a device. Has anyone else done this type of modification (using the stock generator)?

Not sure if this unit could be converted to an Indian Autolite generator. It says 3 brush but I believe the third adjustable brush needs to be eliminated and you convert it to two brush and run the output through the solid state regulator.

I had Indian Frank convert a beat up 6v to 12 v with electronic regulator.It looks like a new stock generator.Cost wasn't much more than a new cycle electric.
Not sure if he offers just regulator but may be worth a inquiry.I think its "Indian frank@yahoo.com'

Howdy chaps,

I run PODtronics on all my Indians with generators converted to two brush. Sourced from the British scene where I’d converted Lucas E3L’s and Miller D6’s, they are rated for 15 amps and perfectly adequate for Autolites. You will have to fuse the positive side of your battery, do not use HD type circuit breakers. I sourced mine from Coventry Spares.

Hi Peter, you are showing exactly what I am looking for. I am familiar with Podtronics products as I fitted a 12v positive ground unit on my 69 BSA Lightning a few years back.

I have sourced the part here:

And I think this is the conversion. Are the wire colors correct? Would you happen to have a schematic? Red is fused to the battery like you stated. Black wire is ground of course (referred to as "brown"). What about yellow and green? Yellow = Generator output (+)? Green = 3rd brush holder (-)?

Also, I understand the need for a fuse and not the self resetting circuit breaker with the internal heater. I guess that could keep resetting itself and cause issues.

I looked closer at my generator. I guess it's a GDE 4041 high output with two wires coming out to the larger type regulator. It's NOS from Kiwi Mike about 25 years ago.

After more research the generator with a cut-out has a single wire output. One wire goes to the third brush and other is case grounded inside the body. The high output is different as it is not case grounded. Two different configurations of field coils.

Dressier Electric in Lewisberry Pa will manufacture, rebuild or rewire anything you need when it comes to charging systems or magnetos.

Thank you Otis. What I am looking for is an internal wire schematic for the High Output Autolite generator. I understand the Standard generator internals and how to attach a solid state regulator but the High Output unit has different internal wires and I just need the info to hook up the electronic 6v regulator yellow and green wire once the third brush is eliminated. There are two wires that protrude out of my High Output generator. The Standard only has one which was the output of the fixed brush. I suppose I could just take mine apart and figure it out but maybe someone here has that info.

Autolite had 2 wiring configurations for the generators as used on Indians, both were 3 brush.

The standard output, or GAS models used only a cutout relay. One end of the field winding circuit was grounded inside the chassis near the drive end. The other end of the field circuit is the + lead which was connected to the 3rd brush. Moving the 3rd brush changed the voltage applied to the + side of the circuit. This is the diagram you posted from my web page. Without making major changes to the internal wiring of the generator, you would need a regulator that controls the + side of the field circuit and simply remove the wire from the 3rd brush and connect it to the regulator control. Again, that's what is shown in the diagram I made. You should look for a regulator that is - ground and controls the + side of the field circuit.

High output, or GDE generators also connected the +side of the field circuit to the 3rd brush, controlling the voltage into the field by moving the 3rd brush. The - side of the field circuit was routed out the top of the generator and connected to the "TC Regulator". The GDE has 2 wires coming out. The larger wire is the power output, and is connected to the + brush. The smaller wire is the field circuit -lead. I did not have a diagram for the GDE conversion, but it's pretty simple too. You now need a regulator that controls the - side of the field circuit. These are the most common types. Simply reroute the field wire connected to the 3rd brush and connect it to the + brush inside the generator. The regulator field control connects to the - field wire coming out of the generator, the small wire.

Beware the confusion of + or - earth and + or - field control, two different things completely! Looks like the Podtronics unit you show is a - ground, or earth. That's perfect for this application. I don't know if it is a - or + field control though. If it is a - field control, then you need to make 1 change to your diagram: The green wire needs to connect to the - field wire, not the generator chassis or - brush as you show it. Can't speak to the Podtronics units.

When I was making regulators, I had 2 designs, + and - field control units. They were fitted into the appropriate regulator or cutout housing for ease of installation.

Thank you Gene. Your information is very helpful. I posted below some instructions from the regulator. It's actually a Wassell for negative ground 6V. I re-drew the schematic. Not sure if I followed your instructions exactly. Maybe it's close. What do you think?
