Sorry I thought I uploaded the picture. I'll try again. 01-410-4964

I found this NSN on ebay. It's the same sending unit with a different top plate. You can unbolt the top plate of the old unit and clock it the correct direction and install it the correct way. Thanks for all your help.

Yeah so I got it adjusted and checked it not running and finally found 2.1vac. The 5v was is while it's running. It didn't solve my issue.

I'm having a hell of a time with this MPU. I've broke 2 now not including the one that was in it. The one I got in it right now I could only adjust to 1.1vac. While it's running I can measure 5.4vac across terminal 16/17. Is this where it's supposed to be?

Testing at the GCU I got 978ohms. A bit high I guess. VoltsAC is leaving me with .3-.4. The signal is not even close to correct. Thanks for keeping me honest. I'll attempt adjustment until I see a proper reading

Makes me wonder what the hell I was reading. Well it's almost quitting time. I'll jack with this some more later.

Is that extremely important as it ran before with the old MPU and the tip was worn off

Yeah mine said 1-1.5VAC

Still no luck. I checked all over the right side with my bore scope and didn't see any data plate. Its got 140 hours on the gauge and tge generator looks crusty and old.. no signs of the panel being ever pulled.the Frequency won't adjust and gauges m8, m9, m1, don't have readings. Of course the...

I've never even had to replace main gen here. I usually get stuck with the ones that don't run.

The tag says mep 805a 30kw 50/60hz. So I'm not sure how to verify that. I'm installing a working MPU now

It's new to me yeah. Another mechanic has worked on it here but no one knows anything about generators. I think I found the problem though. The mpu looks messed up it has a thin copper rats nest on the tip. Other MPUs I've dealt with would prevent the Gen set from starting so this is new to me.

Good looking out! I'll check. Look what happens when I get myself into a government job 😅

Oh wait the pick up on the bellhousing?

Sorry I'm still new to this. What is an MPU?
