2010 28HP won’t charge.

So I have a 2010 Skag Turf Tiger with a 28 or 29HP twin EFI engine. I had the regulator fail once and replaced it. Now my charging system has quit again. I tried a new regulator but no go. So I guess this leaves the stater as the problem? I have not run a diagnostic on it yet but am I missing something. Also I have misplaced my diagnostic directions. Do any of you have an idea what I’m missing?

To check the stator you need to test the AC voltage output. Unplug the stator from the harness, put your DVOM on the AC scale. One lead on one side of the plug and the other lead on the other side of the plug. Run the engine at high idle. You should see above 26 volts AC. If so, the stator is fine.

After the Stator test mentioned above, hook the same two leads up to the voltage regulator you should see 14 volts or so there, also the voltage regulator needs to see 12 volts from the ignition

Sound like a FX850V EFI but that is just a guess. No model and spec number given.

The stator AC @ 3600 should be a lot higher than 26 vac.

It’s not an FX850V. But if it were, this info is correct @StarTech.

See that why people needs to post the engine info. I have yet the Hp rating fixed in my head when comes to the Kawasaki engine especially. I just done with a FTX00 engine but that one is over 30 hp but it was a DFI and not EFI fuel system.

FXT DFI, boat anchor. 😄

Well the one I repaired is a very strong running engine after I replaced the blown engine head gasket. Now of the Hustler dealer told the customer he needed a new $4000 engine. Big difference between $4000 and a $300 repair.

They are a beast of an engine when that Nikki fuel system is cooperating. Diagnostics on that throttle body can be a bear. Not worth the money to replace it.

A bad ground connection to a regulator can kill them in very short time .
You have to test that then test the AC between both alternator wires and between each one & ground
Then the DC at the terminal to ground then the DC at the battery very common to loose a lot of Volts between the rectifier & the battery for bad / corroded terminals.
ZTR electrics are a disaster
Almost none of them are properly secured so they shake & break
Then you have battery cables that are exposed both ends, not sealed so water condenses on the trminals over night, wicks down the cables and rots through them in the middle because all of them are fitted as a hang down loop .

Could be wiring or the charge coil under the flywheel. Or could be the starter solenoid.

True but generic is close enough for this one. When he checks for VAC coming from stator he will probably get little to nothing since he already tried a new regulator. If he gets 26 or 25 or 30 or 35...or if his meter isn't very accurate lol, any voltage that high means it's time to do some more digging into problem because it's prob not stator.
But yes, without model numbers, engine model etc, we are all guessing but at least it's educated guess for some of us.
