Some may remember when I asked for help with the '71 when it was not charging the battery. I never found the problem with it and I never got it to charge. I thought it was the rectifier, so I took the one off of the '65 and swapped them. Still not charging! All the conections are good. Any thoughts on what it is?

What motor do you have?

I just looked in the manual on the Kohler site, nothing at all helpful.

What motor do you have?


Sorry, it is a K321 in there. Forgot that! :laughingteeth:

Does your engine use starter generator or flywheel stator?

It has a flywheel stator. Do you think it could be that?

Do you have this manual? Starting on page 80 is the testing procedures.

should be two wires coming from flywheel use a volt meter and check voltage with engine running. From the manul looks like the black wire and ground should read ac voltage before diode and dc after diode.

Nope, didn't have that one. Thanks!

1) I have tested it before, I know that is is below 12.5 volts

2) I can't test this, if I disconnect the battery it stalls.

Numbers 3 and 4 I don't really understand?

jms, I will test this and see what happens.

Ryan, Look where the wires connect to the engine, usually the stator wires will have a separate connection as JMS said 2 wires. disconnect them fire the engine up and test your voltage at that point.

I went to look for the stator wires, I figure the two wires coming from behind the backing plate are for the stator, those wires go to the rectifier.

I tried to start it to test the voltage, but the gears on the shaft stripped. I switched with another starter and that one was bad, so I made one out of the two. I tried to start it but it would only run on either! I am going to have to clean the carb before I do anything else

Do the stator wires matter which prong they go to on the rectifier? The wires are both red and are the same.

Bill, what do I test the voltge on? The battery, or the two stator wires?

Looking more at manual there are different amp stators. you should look at manual Kenny provided and go from there. The first one has two circuits one for battery one for lights with single diode for changing ac to dc. The other ones use a rectifier to change ac to dc voltage.

I cleaned the carb, but I am still having a problem with the starter.

When I took the bowl off of the carb it had some jell like stuff in it. Anybody know what it is? And why it happened?

Yuk! Must be a by-product of the ethanol. Bet there is more inside the carb passages.
As far a testing for charge, I would hook a volt meter to the battery. Once you have it running, see if voltage increases in the battery. If that doesn't change, then checking connections (which you have already done most likely). Finally, checking the wiring back to the stator per #3, which is using an ohm meter. Do not use the ohm meter on a circuit the is powered (has voltage). Someone may correct me here, but I believe the closer the reading is to 1, the least resistance you have.

Yes, the inside of the carb had some but you could see it best in the bowl.

I did test voltage on the battery when running and it was no better then when not running. I will try and test the resistance of the stator.

I started a thread on the ohm meter. Some good basics in there from the members. Might help the get you an idea of what you see on the meter.
