solid state votage regulator for '53 SC

riverbend · Jul 16, 2009

The voltage regulator on my Super C has been troublesome. A new one lasted a couple years.

Is there a solid state voltage regulator for 6V, + gnd, generators ?

Thanks

Greg - I've not been able to locate such a thing - I kinda doubt they exist.

However I've had discussions over a few beers with an electronics whiz buddy about this. He suggests it would be relatively simple to design/construct 6 volt solid state VR using inexpensive, off the shelf parts. Perhaps sometime I'll convince him to throw one together for me to try out.

Note also it would not be difficult to combine a solid state cutout relay (about $25) with a mechanical VR to create a hybrid VR. The combination would eliminate the VR's cutout relay and (theoretically at least) create a somewhat more reliable VR.

Any idea what has gone wrong with your VR?

A bit pricey, but it doesn't cost to look.

Interesting!

It isn't mentioned specifically. However as it's from Corvette forum I suspect that VR is for 12 volts.

Or were the earliest Corvettes 6 volt???

hey were 6v for 1953 &'54, then went to 12v. Expect that since he builds these himself to fit whatever regulator case you send him, that he could do 6v, 12v, pos or neg ground.
Only way to find out is to contact him.

Bob,

I'm not sure but I think that the points burn. If I file them the regulator Works for a while. With the cover off I can force it to start charging by touching the lower contact and closing it.

The hybrid version sounds interesting. Someone is making a 6V, + gnd, solid state VR for old bikes, but I think it would be a little light for a tractor. A new aftermarket VR was bad out of the box. Our local tractor supply store has US built regulators for about $55 (vs ~$30 for the 'standard' one).

It is amazing to me that electro-mechanical regulators seem to be a lost art. If you can find old regulators, I would grab all I could. I have an SMTA (1954) a IH101 combine (~1950?) and a 1962 Chevy PU, all three with their original working electro-mechanical regulators. If I have a problem, I'll give tender loving care to keep them alive rather than replace with current day junk.

What I'd like to do, is take a chrysler altenator and solid-state regulator and fit it to the SM. And mount the regulator in the battery box. They had a temperature compensator built into them so that they would charge harder when it's cold and lighter when it's hot out.

That is the most galling thing. I have never touched the VR on the H. The '58 MH model 60 combine has the original VR. The SC had been replaced and has been no end of trouble.

I don't mind paying for something once. But I hate paying for cheap parts over and over again.
