Engine runs like a top now! A little smokey but I haven't ran it long enough to seat the rings. My oil pressure gauge is bad so I ordered a new one and don't want to run it long until that's replaced. Other than that it does make power and function how it should!

Any brands you recommend? Sender/ gauge combo?

You nailed it! 137T was hooked up to the lug (regulator) not excite. I swapped em over and it works perfect now! Can't thank you guys enough for all the help!

Ray can you help me out with the alternator wiring? I've got no wires on the stud labeled "excite" or "ac tap"

I'll give that a shot soon and let you know what happens. This is certainly an interesting situation.

But something I find strange is that if the engine is off and I just cycle through s1 functions everything works normally. And If I just bump the start but don't allow the engine to actually start, when I switch s1 back to off the solenoid closes and the panel turns off. It's only when it's...

Yes that is correct

Just checked it, and yes it appears everything stays on and keeps working normally

Alright, tested all the wires, they all check out okay. Signal removed from gauge ohms at 240. 23 volts at the gauge and ground is perfect. Attached photos are the gauge with key off, as soon as I switch it to run position, and the photo of the start switch. It is indeed there. So I'm thinking...

Hey fellas, recently purchased a 2009 mep802a off gov deals and got to working on it. Ended up having to rebuild the engine, got that done and it fired up beautifully. Makes power but I've got two issues. Oil pressure gauge is pegged at 80 and stays there even when off. I know it's not making...

Everything in the engine is still standard size! I have no reason to believe this engine was ever opened up in the 3400 hrs it's logged so far. Just really hoping after all this it makes power

I've had the head torn down and soaking in my parts washer. My rebuild kit came with new valves, tomorrow I'm going to lap them in and pre-assembled the head. Then I will test for leaks. Today I got the new pistons and rings installed, new rod bearings, pushrod housings and seals replaced. I'm...

Thanks for the heads up. Most of the parts I ordered I'd rather not use used parts but if I need anything else I certainly will!

Another little update plus more bad news, got the pickup and relief valve removed. I'm unsure if the relief valve plunger is supposed to move or not but when I went to pull it apart the plunger was completely seized and it was very rusty internally. Heated it up and got the plunger out, it was...

I contacted HQ on eBay and they list new pushrods for that engine so I ordered them as well as the rebuild kit. I was not aware of letting the engine sit before cranking, so thankyou for that advice. I wonder if I bent them trying to start it. Is there anything i should be looking at as to why...

Have you ever dealt with hq motor service on eBay? They have an entire rebuild kit for 299. Pistons and valves included. I also just did some more digging. All 4 pushrods are bent!

I could use the rod bearings. I'll change them because I'm here. Thanks!

I just read that thread. Lots of good info. I go out in the shop and take a photo of the top of the piston to see what it says.

I found a kit on eBay that lists the pistons. I'm sure they are aftermarket. Mine are not damaged and can be saved so maybe I'll just reuse them and throw the new ones on the shelf if I ever need them. I see marks on them I just don't know what the original size is to tell you if they are oversize
