Personally I'd suggest checking the rotating diodes next before investing in a DC PS.

I found a manual about the gen head at: Gen Head Manual It talks about using a 12 volt battery with a 30 ohm current limiting resistor to apparently flash the gen head. See PDF page 52 You may want to test the rotating diodes in the gen head. If they are toast the rotor won't generate any...

Very common issue. Had to replace those on my 802. Replace the hose with a piece that's longer so that it's not bent so sharply when installed. This will help with cracking down the road.

Unfortunately the Operations and Maintenance manual has very little info in the Generator Runs but doesn't produce power section. Yes, Yellow and Blue are the two wires to the exciter from the VR. The VR is powered from Red and Red. The VR system relies on "residual magnetism" in the gen head...

The original fuse holder is about $100! I'd suggest finding one rated for similar voltage and current capacity. They are much cheaper. Be sure what you pick can handle the current.

Do you have the paralleling cable?

From my understanding of the set that dip switch setting is read by the DCS at power up to let the DCS know if it's in a 1030, 1040, 1050, 1060 or 1070. The DCS then responds accordingly based on that dip switch setting. That's why they immediately knew they were in a 1050. The engine dip...

I assumed that was the case. Only Distribution A for us.

Other pair would be the Quad Winding Output. Can you find where each of the 12 leads go? Do they go to individual posts on the reconnection block? If so that would good. The TM's for the 1050 are useless for determining that. The DCS might get confused if reconfigured for 120/240. Don't know...

According to the TM PL and the schematic of the rotor there are three of each type. Of course the TM could be wrong

Wow, :eek: The available TM's for this set is very inconsistent! So it may not be a 12 wire head even though the -24P shows 12 wires. The -24P TM dated 1 July 2011 indicates switch S501 is used to change the output phase/voltage and that it has 3 settings for 120/240, 120/208 & 120 and a 12...

Good news is it has a 12 wire gen head. I'd assume with some wiring modifications one could convert it to 120/240.

I revived my effort to make a replacement this weekend. Had to wrap two other board designs first. Hopefully I'll have some good news this July.

Its the round item hanging down from the T fitting near the dead crank switch. Number 7

Have you pressed the TEST button on the Fault Monitor to test all the lamps in the Fault Monitor. If the LED inside K12 is illuminated but the Fault monitor doesn't have lamps illuminated it could mean there is a failure inside the Fault Monitor itself. They do fail. I've repairs a few of...

As a general rule an AC fuse can be used in a DC application as long as the DC voltage is < 50% of the AC voltage rating of the fuse. The one spec'd out in the TM is O.K. to use up to 60 volts DC.
