Charging problem

[htiek126]

Is the VR built by the same manufacture and is it the same packaging?

Greg & Keith:
1. According to my tests, the 1401 alternator puts out 30+ AC volts at the output plug; thus no rectifier.

2. The Kohler must have a built in rectifier, because I have AC going in and DC coming out.

3. The part # ST435081 is jacksmallengines.com part number, but might be the same as Kohlers.

4. Keith: The Kohler regulator looks different (smaller), and I cut the plug off the old regulator and used connectors to hook the old plug to the new regulator. That way I can always go back to a Yanmar reg. and plug it in.
It comes with instructions as to AC in, ground, DC+ out, etc.
When I get home I can take a look at the wire colors. Some of the newer Yanmar regulators have a 6 prong plug, and not 4 prong like the 1401. Two of those prongs are not used. If it stops raining, I will post a picture of it and the wiring.

Keith,
That Kohler regulator is not the same part as the Yanmar regulator. I'm sure it is a much simpler device, and doesn't have the 6 or whatever modes of operation the Yanmar regulator does.

I would be interested in seeing the schematic...

It should have at least some of the modes of the Yanmar regulator, hopefully, the ones that prevent damage to other components.

Jim,

Glad everything worked out!

Thanks,
