Conversion kits are available but that brings up another point. A person never knows who manufactured the voltage/current control units that go with these 10si conversions. If there is more than one source, then some may be better than others. Bob has the caveat for using 12-volt systems, The modern type bendix and changing the starter fields to match a 12-volt starter should make it usable but I've heard there are supply problems with the modern Bendix drive units. It seems like there is always something to put a damper on this stuff.

The modelTstarter.com voltage regulator is a cut out with a VR inside as I mentioned before. It's a bit different than John Regan's Fun Projects unit. It charges till it reaches a set voltage and then shuts the generator off. It turns on as soon as the battery voltage drops off to 6.2 volts or so. This makes the amp meter swap charge for discharge when it cuts off so it's definitely a different critter than a constant voltage regulator. They say that the internal components should always be available where the old Fun Projects VR chip was obsoleted by Texas Instruments.
