That's what we are all here for. Help, or helping. Glad your problem is fixed. And yes, you could have figured it out. Might have taken a bit longer, but you would have found it sooner or later! Take care and have a nice sunday! Ours is about over, and looks like rain again.

Read the -34 book. I posted them in SS. It explains everything. And yes, I would call it easy to check. And repair.

We were told in AIT that this was indeed something we could do to excite the main gen when all else failed. And in fact, one of my fellow CWO's did just that in El Paso. So give it a try. But if you have voltage on F-1 and F-2, there is nothing in between . Nothing to hinder the main gen from...

If you have 24 volts on F-1 and F-2, you need to pull the rear cover off the gen set and then remove the end bell of the main gen. See if F-1 and F-2 wires are undamaged the whole way from one end to the other. I have found on a number of occasions, that one or the other wire was pinched/cut...

So we have determined we have exciter voltage out of the static exciter box, even shows on the voltage meter when holding up on the start switch. What plug, what pins for output of exciter? What voltage shows on the meter, 24 volts? Or something else. Can the static exciter box produce 24...

The NSN 5930-01-246-9266 is the proper NSN to fit the MEP-005A. The part number 70-1105-24 is not listed in the parts manual. Are the NSN and the part number both listed on the switch? The only NSN that is interchangeable with 5930-01-246-9266 I know of, is NSN: 5930-01-023-4343 I would give...

Wanderingwillys, This is hard to believe. CT1, CT2 and CT3 measure voltage for your meters. So if your meters are reading right, the G-1, (main gen) has to be putting out voltage. The fact that the hertz meter is reading means A.C. is present. As the thermal watt converter uses an A.C. signal...

Can you give me the part numbers of the old and new speed switches? The NSN also, if you have it? Not all speed switches are the same.

OK, A and B are your start circuit. When the engine hits a certain RPM, the speed switch opens one set of S-9-1 contacts, to lock out the starter. There is another set of contacts to the S-9-1 circuit, that close. energising the K5, (field Flash) relay. Then and only then can the exciter pass...

Yep, the speed switch has to be functioning for you to see if the contacts really open/close. How did you check the continuity and discontinuity checks? If the speed switch does not let the exciter voltage, (the 24 volts you saw) through to the main AC, then it will not show up at the 110 volt...

Hope this worked. This is a drawing of the static exciter. Item 76 is the volt regulator. That is NORMALLY the problem. You need to download the manuals and start looking at troubleshooting, and the schematics. Unless you have another gen set to take parts off of, you are going to need to...

Yeah, the -12 manual has schematics and wire diagrams. Should be in the SS section for Generator manuals. For generator mechanics, the control panel end of the generator set is the REAR of the set. So, if you look on the left side of the generator, open the front door. There is something that...

Old Dude! Have someone measure with a multimeter at the 110 volt outlet, while you hold up the start switch. Do you get absolutely no voltage? You should get at least exciter voltage. 6-24 volts, D.C. If not, then start reading the schematics. Normally, this is a static exciter box problem. In...
