Is there a way to identify F1/F2 wires from the rotor to the exciter? Neither of the wires are marked.

Well I am back. Started out on the generator to do a load test today, but started having issues. First, whenever I start the generator it never automatically excites, I have to make sure to hold the start. When this happens the frequency meter jumps to 65 then to zero then stabilizes at 60...

Good news, I ordered a new exciter and installed it today. Everything works great now, still have to load test but she's producing power! Wasn't too bad of a job swapping it out. Thanks again to Guyfang for helping me troubleshoot this problem.

Thanks for the heads up. I am using a Fluke 77 for testing. The exciter stator was good at 11 ohms. Th exciter rotor leads I got .5 on all leads. I couldn't get any readings measuring the rectifiers. When testing the exciter rotor I was getting a reading from both F1+ and F2 with the rotor...

I am going to test the generator rotor tomorrow. Hopefully it checks out and I only need the exciter rotor (201-3466) and rectifiers (358-0070 & 358-0069)

Well I went through the TM and it appears the exciter rotor and rectifiers need replacement. I really appreciate Guyfang assisting me in troubleshooting this problem. I have messed around with 802/803 generators for a few years and this has been a great learning experience for me. Now it's...

Ok, thank you. I will get on this and hopefully get it figured out.

I have no HZ or AC voltage. From my interpretation of Guyfangs guidance - I should be getting 24v to A1 6 on the A1 but I am only getting 9 volts. I have 26 volts leaving the K15-8 to the R14. 24v leaves the R14 at 10 volts to the CR2 and then back to TB5-17.

Well I though I had it. R14 was getting 26 volts on one side and 9 volts out the other side. I checked another working generator I have and the R14 had 25 volts on each side. I then removed an R14 from a parts unit and installed it on this 803 and got the same results as before but instead of...

I have 24v coming out of K15 but only 8.99 volts at A1 F+

Thank you for your help Guyfang. Your a great asset to SS! I'm done for the night as well and will hit it 1st thing in the morning.

Just tried it again and I do have a constant 24v on #7 when holding the start on the S1

Ok, idiot award to me, I misread your post and measured the leads going to the mag pick-up....... Just measured like I was supposed to and got 3 volts.

0 volts at the mag pick-up

I removed the mag pick-up - it had quite a few metal shaving on it. I removed the shavings and reinstalled it. Good news is the grinding went away but still no power. I am getting 3.3 volts on the lugs and on the convenience outlet.

Has anyone had an issue with a grinding type noise with field flashing either an 802a/803a? I am working on a 803 that has no voltage or hertz. When I hold the start to flash I get a grinding type noise. On the S1 #7 I get 24v for a blip and nothing happens. Also, using a good field flash...
