Havin problems with my antique lawnmower tractor, A 1971 GT-14 wheelhorse. It charges okay if theres no other electrical load. However it has a electric pto clutch to run the blades, and it will only last about an hour on a good charge before the clutch doesnt have enough voltage and the blades stop. Not realy familier with this at all, does anyone know how to test a voltage regulator? This has a small aluminum finned box with 3 spade connectors coming out of it. My only other guess is the PTO clutch is drawing too much for the 'alternator' underneath the fly wheel to keep up with. Any ideas? Thanks

Do the Briggs system work in more or less the same way? I have 2 that don't charge.

It depends upon the model. Some simply have a single diode, other (usually "bigger") units have a rectifier/regulator like the Kohlers.

I got the rectifier out and all cleaned up, the output side of the recifier wire broke off the ignition switch, gonna order up a new switch, just ran the rect. wire to the Pos side of the battery, worked great all day and still fires right back up. Thanks again guys!

A very common problem on these charging systems is a poor ground between the aluminum rectifier box that you describe and the frame. Try removing the screws and cleaning the contact areas. Frequently a user will replace the rectifier and the problem goes away just because the screws were corroded or rusty but the original rectifier wasn't bad at all - just not making good contact.

With the connector off of the regulator, and engine revved a bit, there should be 25 to 28 Volts AC on the outer terminals. Stop the engine, and put the connector back on, and start it again. There should be somewhat over 14 Volts on the middle terminal on the regulator, and about the same at the battery. Typically, the current from that middle terminal passes through the ignition switch on it's way to the battery, so a bad switch, or dirty terminals at the switch can prevent charging.

Here's a link to the Kohler manual, which has a section on the charging system, on-line:

Good post Bob. I am having a similar problem with a Kohler CV20 engine that I just bought a new regulator/rectifier for - but the amp meter on the machine still shows about -0.5 amps when the engine is running, and about -7 amps when the mower deck (electric clutch driven) is engaged. I will take a look at the ingnition next.
