Angry 99 VN750 - 5th stator??? Brand new shindigen FH020AA

Hello,

I have a 1999 Vulcan 750 and I am having stator issues big time. We bought 4 stators so far and 3 regulators. After the 3rd stator we bought a Shindigen FH020AA MOSFET Regulator/Rectifier and relocated it outside so it could cool better. This has lasted 6 months and now the stator is a black crispy burnt pile of trash again.

The funny thing is that it would charge the bike still with no headlight connected and put out 14-15 volts with no big loads. Tested the stator and all three phases short 0.01 ohms to ground directly! lol... Each leg tests 0.01-0.08 to one another.... Pulled the stator out and man its burned so bad I have no idea how it functioned at all.

New stators (oem, regular and this last one was a high output higher $ one), new mosfet r/r, new wiring.... why does this keep happening? What can be done to stop this from happening so often? We're just at a loss...

I'm currently (somewhat) dealing with this; stators keep grounding out.

I'm thinking it may be my stator mod plate allowing the stator to touch the rotor when it gets hot, so I am going to use a pre-made one from gxe (if I can find it..)

Do you have any damage to the wires that are inside the engine? If you don't tie strip the wires away from the rotor you run a chance of shorting them out.

Here we are again.... bad stator.

I JUST replaced the stator 1000? miles ago! I got so pissed off I cut out the original fuse box and all the stator to headlight circuit bs. We have the stator mod plate now so we dont need to remove the engine...

I installed a new generic fuse box with 10a fuses for tail/running lights, head light and signals, aux, fan, coils, ignitor. Installed a new 40a relay that is switched on by the key and cuts all power to the bike when the key is off.

Installed an interlock relay so the bike will only start in neutral or with clutch in.

Installed a Brand new shindigen FH020AA regulator 2 or 3 stators ago and its wired directly to the battery with a circuit breaker.

The vulcan 750 IS A PIECE OF ****. BAD DESIGN. PERIOD.

WHY do I, and others, keep losing stators? All new wiring, NOTHING reused for charging. Removed the stator to headlight wire that turns on headlight with bike running only (light on with key now).

I mean... whats left!? flywheel?????

It has been good for about 1000 miles since I put this last one in.


Im gonna blow this piece of crap up here soon.... and then bury it. I need to figure out why this happens.

At some point I have to wonder, how's the temperature on your bike? I'm wondering if some of these bikes the oil temps are getting too high and cooking stators. .. . . .

All other brands bsides OEM rewound are known to fail shortly after... On my bike between me and the previous two owners when through 10 Stators in less than 6 months. After my second Rick's stator, I went with TPE stator and Shindegin MOFSET R/R and haven't had a problem since. Its now been 7 years with out a single charging system issue.

Well, after I disassembled the last time and found the red lacquer type paint coming off the windings I said... well this is stupid. They put such a tiny coating of the paint on and it cracks and comes off...

I went and bought ceramic header paint good up to 3000 degrees F at advance auto... figured what the hell... I had a new warranty stator coming.

I painted the stator with 4 coats of the ceramic header paint... ALL Sides and sprayed it so it dripped and ran everywhere... to get into the cracks. after 4 coats the finish was nice.

I installed it in the bike and its working very well now. 1 week and 100+ miles so far..... we shall see how it goes.

Ceramic paint = insulator to electricity and the high heat paint should hold up to the oil temp. The paint is also gas/oil resistant.... again only time will tell but having the whole thing coated is better than the aftermarket bs.....
