Vanguard 16 hp stator replacement

[Kabruta]

Hi guys. My max seems not to be charging. I have a vanguard 16 hp. Does anyone know how to diagnose whats not charging. I disconnected the connector coming out of the motor and with a multi meter I dont see any voltage coming out? Stator? Are these 10-16 amp stators? Any help will be appreciated.

I'm not that good with electrical, but I believe it is a 10-16 amp stator on a Briggs Vanguard. To replace it, you have to take the metal engine shroud off, take the flywheel nut off (32mm I believe, but I'm not 100% sure), then get a flywheel puller and start working it on, give it a couple hits with the hammer and then there is your stator.

This site has a very good search feature that you can utilize. I found this post from a few days ago that may help you.

I would google it, diagnostic that is.. seems like it's supposed to put out 30 V AC off the stator terminals with the regulator disconnected, don't take that to the bank, though. The magnet strength in the flywheels is supposed to be the difference in the amp ratings..

Also, always be careful when R&R the starter, the stator wires can get pinched between it and the block.

ac output on the stator? I was testing using 12 volt setting. I am not that good with a multi-meter. Now that I think of it, when I had the meter on registering no voltage on the 12 volt setting, I remember when trying to put the electrode on it I remember a spark from the connector like I might of grounded it out. Do I put the multi-meter on ac?

You would use the 12 v dc test on the charging wire coming from the regulator toward the battery. The AC test would be between the two stator leads, with the regulator/rectifier disconnected from the stator. Test done with engine running.

Isn't there a fuse on max charging systems? I don't know.

I feel so stupid trying to figure this out myself. Here is what I have noticed. No power coming from the red wire out of the regulator. I get a spark if I touch the two wires coming from the stator. (stators working) My best guess now is the regulator. Anyone agree? Thanks again for this help.

There will be a 2 wire connector coming out from under the flywheel going to the regulator, it will be a white connector, un-plug it. With your meter set on AC, there should be 28-32 volts AC at that connector,(engine side), when the engine is at full throttle. If you have AC voltage there, the stator is working. Now, with that connector plugged back in, unplug the red connector at the regulator, put your positive meter lead there, the other lead should be grounded against the engine case, you should have 13.8-14.2 volts DC at the red wire coming off the regulator. If you have ac voltage in, and no DC voltage out, the regulator is bad.

I am getting no power out of the red wire from regulator. I just ordered a new regulator. I will let yall know how it turns out. Thanks a lot guys.

Did not see this until now, I was the starter of the other post. Turned out to be the regulator for me. Easy fix just bolts right on. Good Luck!

Update. Replaced the regulator and I have charging. Thanks for the help
