OK. Start the set up, and while doing that, measure to see if you have 24 VDC on S1, pin seven, AS LONG AS YOU HOLD UP S1 in the start position. This is the excitation voltage, to the main gen. It comes from S1-7.

The Quad circuit fuse is normally located next to the A1 volt regulator. Its a big fat fuse. Pop it out and test it. If its good, pop it back in. If you are still not sure what I mean, take a picture of the inside of the control cube, (cabinet) and post it. A2 is the fault indicator. If you...

I look often during the day and at night. I hate phone text, as my sausage fingers and the tiny keys are a problem. And I am famous for leaving my phone on my desk all day. OK, so the adjustment fixed the starting problem. Next, are you holding the S1 in the start position long enough? If...

Back up. One problem at a time. Have you downloaded the TM's? Have you looked at them. Is this set new to you? Has it ever worked right? The "sometimes" making power could be because you do not hold S1 in the start position long enough. You need to measure how many VAC you have out of the...

Sorry to hear that.

Thats a good question.

I would have to see what is hooked to pins 1 and 3. I am getting ready to boogie down to the Bodensee to pick up my wife. I leave in the morning, get back on tuesday. Just looked quict. Pin one goes to through FU-2, quad fuse to the F1 on the G1, (Main Generator). Pin 3 goes to the F2 on the...

The field flash voltage should be DC voltage. If you are getting AC voltage to the exciter windings, something is wrong. I would replace the volt regulator. Below is a passage from the TM. 1-12.8.2 Field Flash. When the engine reaches sufficient speed (900 rpm), the magnetic pickup causes a set...

The voltage produced and measured from the Mag Pickup should NOT exced 3 volts. Adjust the mag pick up as described above. If for some reason you can not adjust it down to 2.5-3.0 volts, the pickup is bad. I assume by 3A limitron fast acting KTK-3 bus fuse, you mean the Quad circuit fuse, to...

MAdams, Its rare that a mag pickup goes bad. Thats a shame. Whenever a 804 has no volts and no freq control, the mag pickup is the first place to look.

This is what I found when I looked up the cage code. GE AVIATION SYSTEMS LLCCage Code 05624LOVES PARK, IL, UNITED STATES Map data ©2016 Google Terms of Use Report a map error Map Satellite Established: N/A # of NSN's assigned: 5289...

Have you pulled the mag pickup? Look at it. If its not ground off, reinstall and give it a try. This is the CAGE CODE. 05624 Its the code for the manufactures name. I am looking for an old copy of FEDLOG, and then we can look it up. This is the Army part number. 88-21061 Proper name is...

The 6 volts you are getting is excition voltage. Have you tested the magnetic pickup yet? Look for it in TM 9-6115-643-24P, figure 18, item 19. It’s located above the starter. Unplug the two spade connectors. Unscrew the mag pickup from the bellhousing. Inspect it. Is it dirty? Covered in metal...

What "Breaker" are you talking about? Do you mean the Ground fault interrupter, (GFI). TM 9-61115-643-24P, Figure 7, item 22. Is that what you are talking about?. On the side of the GFI, there is a small switch or reset when the GFI gets tripped. The GFI only trips when you have a ground fault...
