Solid-State Voltage Regulator Conversions

Your "can" looks large enough to easily install "something else" in there. I'd just get a N.O.S. replacement to match your 12v unit and stick it in the box.

Solid state? That might be a little more difficult.

Generator regulators consists of three separate units.

1 The cutout, the oldest of all generator accessories, is a relay which disconnects the battery from the generator when not charging. These CAN be replace by a huge silicone diode, and example of one I did on a starter/ gen on a garden tractor

These are a "two unit" regulator and have no current protection relay. The cutout went bad, so I found a bridge at Radio Shack and wired two of the internal diodes in parallel. Not pretty, but hey..



2 The voltage regulator, which works surprisingly similar to an alternator -- it 'reads' voltage, and adjusts field current to keep charging voltage where it should be

3 The current relay. This protects the generator from burnout. It reads current flow out of the generator and starts to drop out as it's limit is reached. THIS would be the difficult part to build solid state, but could be done.

I don't know if there are specialty outfits which do this or not.

As I said earlier, the EASY way would be to find an automotive one and mount in your gutted case.
