Mep 006A won't turn over

Good Morning Guyfang, Still having issues. I had to take a break on it due to work load. Just started messing with it again yesterday ironically. Fuel being dumped into Oil still and no power lug side of Output contactor. Mentioned above, the leather seals on the injection pump could be installed wrong allowing fuel into the engine. It cranks and runs, blows white smoke. It takes time for the little tank over the injection pump to fill back up each time as it drains down after sitting. I asked in a new thread I had started yesterday ( as I didn't think this was still active) if someone has a diagram or picture how they are supposed to be for when I take it apart. As for the power issue, I figured I would start with the cheapest thing first and replace the "Open Close" switch first as nothing happens when pressed with way.

I would suggest that you stay with one thread. First off that's the rules, but more importantly, its harder for you to get help. And its important for you to close the loop. If you don't tell us what you have done, then its impossible for us to help you. You need to start on one problem, and fix it. Often that fixes several other problems.

Changing parts is not the answer. It helps the economy, but that's about it. So pick one or the other thread and lets stick with just that thread.

The lack of electricity was a new problem which prompted new thread since it was different than my original fuel issue. I want to make sure I can get power, that the electric generator part of this unit is still working before dumping another $1,600 into a new injection pump only to find out I’m not going to get power.

If You want the injection pump rebuilt i would look into Area Diesel before spending that much money on a new one.

The kit to rebuild the IP is like $30 for the basic kit, or a little over $100 if you go with the upgraded metal governor weight basket.
If you only need to replace the umbrella seals that are leaking fuel into the crankcase, those are "external" to the pump and don't require any disassembly of the pump itself, just removing the pump from the engine and replacing the seals on the pump's input shaft.

I am beginning to think the electrical part of this unit is going bad. I feel my rpm’s are high enough to get the 60 hertz I need, but the gauge isn’t moving at all, so I’m thinking it’s a power issue.

Nothing of the kind. It is not an electrical problem. Your throttle cable is hooked up wrong, or its hanging up on something. Do you have a multimeter that reads hertz? How do you feel that the RPM's are high enough? The gage, as mentioned before are not real reliable. But if you have AC voltage, you have hertz.
If you have a Home Depot nearby, for $28 you can get a Kill-A-Watt meter that will plug into the 120V courtesy outlet, it will accurately read volts and Hertz.
Most likely your gage or the frequency transducer that drives the gage is dead.

You also need to read the -34 TM about how you pull the IP. Its not hard, but read the TM at least twice. Get it wrong, and you will regret it for ever. Say something here before you even get started. We can give you a few tips that will help.

So today my gauges read and it said I had 60 hrz. I put a meter on the left side of the breaker and got 470-471 in voltage. Still nothing right side/lug. Tested switch on panel. Seemed to work as it should as it was closed until pressed down and then open. Anything else to check? Ordering injection seals now. IMG_8954.jpegIMG_8951.jpeg

OK. The AC output Contactor is CB2. The Switch to turn on and off, the CB2 is S3. The light that is suposed to come on, when the CB2 is closed is DS6. The Battle short switch is S7 and the light that is supposed to come on when the S7 is pushed up to turn on the Battle short function is DS7. The DC power cuircuit breaker is CB1.

Now, push in the the CB1.
Turn the S2 to the run position.
Press the DS6 & DS7 in, one at a time. Do they light up, and when you release them, go back out? If so good.
Place the S7 in the up position.
The DS7 should light up.
Then push the S3 up.
You should hear a thunk, when the CB2 closes, and the DS6 should light up.

Do this and tell me what happens.

I am a little confused with all the ds6, ds7 etc… so I took a picture of my panel. The circuit breaker switch is always closed and according to the instructions you press it down to open when shutting the unit down. It does move up, but looking at the back of it, there are no wires attached to top leads. Light works, but never seen it lit while operating.

It may not be 'hard', but I got real tempted to use colorful language trying to get the injector lines on the back side of the pump to break free. I know I bought a special short 9/16" socket and a 3/8 breaker bar for it as well as a 'torque adapter' and a set of curved wrenches. I know the curved wrench didn't help but I can't remember about the others. I know one of them required me using one open end wrench to extend another one and I still ended up having to take the charge pump portion off to be able to get to everything. It *can* be done, and the TM did help, but be prepared for a series of fights getting the injection pump on and off.

The TM has a page that lists all the reference indicators and what they are. It's important to become familiar with these references. because everything in the TM and schematics use the "S2" and "CB1" etc. references.
Do as Guy asked, if CB2 does not close and DS6 does not illuminate, the TM tells you how to test CB2 in order to determine if the issue is with the contactor itself or the switch/wiring.

The procedure to test the Main load contactor CB2 is on page 3-71 of the -12 operator and organizational maintenance manual. If you find that it does not close when applying 24V to pins A and B of the contactor's connector, try whacking it with a rubber or dead blow hammer while applying 24V.
80% of the time this will free up a stuck contactor.
