I have followed these instruction... although late in this string...& not everything is as what others have. Connect your jumper wire to the solenoid side that has at least +12v DC. Test with your DC voltmeter. Leave the wire hang for now. Disconnect the 3rd wire down on the VR which I think is 2 wires on 1 connector. Correct me if yours is different. Now connect your meter to your outlet on 1, 110v side. Either one will do and you can even do the test on both. Set your meter to AC voltage. Start generator and let it run for a minute or 2. Now connect your jumper wire that is hanging to the wires that you removed from the VR and see what you meter reads. Just run it long enough to get the reading and then disconnect it and shut down the generator. . Model# = 09592-3 Serial# = 3248261 I have a auto Line/Generator switch (attached pic) I see no "beaker' on the generator other than the 2 output(ACV) red light has not come on..ever. 2.5 ACV from both outputs as found.. connected 2.5 ACV from both outputs -+12dcv to #3 dual connector(disconnected)    |

Your jumper wire has a constant 12vdc, correct?
Were you testing for AC 120v right at each breaker?

Yes... jumper was connected to the hot(battery) side of the starter solenoid..checked for +12vdc Yes... DMM connect to the neutral(spider of white & green wires) ...& then to the breaker(s). I probed both sides of each breaker, just to be sure the breaker(s) wasn't the problem.

Then I would next suggest you separate those 2 wires that you disconnected from the regulator and determine which one goes to the brushes and do an ohm test between that wire and ground.

Used the ground ...black wire to fuel shutoff. ...checked between ground & the disconnected VR#3 wires, then each separately... infinity... nothing.
BTW VR#1, VR#2, & VR#4: all are 0 ohms to ground.

Try using the generator housing for ground. You should be getting a reading between ground and the wire from that 2 wire connector going to the generator brush assembly.

OK...went for the Stator housing for the ground.
still infinity on both VR#3 leads.
..this would indicate the brushes are worn to the point they don't contact the slip ring, the wire coming back from the the brushes isn't grounded or the rotor wiring has failed?
..or am I jumping ahead? FYI... I have ground up rebuilt a 1985.5 Mustang SVO, wiring & all. So I'm not afraid of get real deep into this.
The guy I bought the RV from said it had never been to burning man... ;-) but I been finding alot of dust, & rust.
...& thank you so much for walking me though this.

Your on the right track but also add the possibility of a coating on the slip rings preventing contact, brush stuck in the holder, broken brush spring, etc.
You have to get in there and find the problem. Just hope the brush holder screws come out. They sometimes break off. Had to drill many of them. Just have to try to keep metal filings out of inside generator head. Good luck and let us know what you find.

Finally got back into this....Work has been a nuisance. So one of the brushes is destroyed.. looks like the housing with new brushes is something pretty available on eBay or Amazon, for $14>$18 . The lower slip ring doesn't look good at all. is this something replaceable or need I look for a rebuilt rotor.   |

Yea that brush holder is pretty nasty looking. Can you get a clearer pic of that slip ring? How deep is that groove?

 The worn ring, seems actually out of round.  |

That looks pretty bad. Almost like it got so hot it shifted the slip ring. I did find multiple places that have a new rotor replacement, the cheapest in Cali. for 236.05 plus shipping. Let me know if you want info..

Yes please.
I wasn't sure if I could ask for that here on the forum.

Also... is the rotor attached to the pulley at the bottom with a bolt...or is it just connected with a key way.
Everything so far is a tap and ply, so I was curious if that will work to get the rotor out.

Sure you can ask. Here is a link to the supplier I found. I know the brand name is different but I believe that is the suppliers name and it is still for a generac. But verify all info when you call. That is the correct part number for your model number generator (09592-3) 5500 watt. If that one is not correct or does not work out let me know as I have other suppliers with availability but just costs a little more. www.rvautoparts.com/077005H-Schwalm-Generator-Parts-Rv-Rotor_p_385270.html |
