    Mep-831a fuel sending unit NSN

    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.

    Mep805a voltage reg kit.

    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.

    Mep805a voltage reg kit.

    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.

    Mep805a voltage reg kit.

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

    Mep805a voltage reg kit.

    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.

    Mep805a voltage reg kit.

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

    Mep805a voltage reg kit.

    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.

    Mep805a voltage reg kit.

    I replaced a5 and it didn't make a difference. The frequency is not responding to the R2 switch being turned. I tried testing the A1 by removing wire 141A and probing between that in terminal 3 on the A1 and got less than 2 voltDCs. Tried the same thing on terminal 10 and 11 and got 107 VAC...

    They both work. Light tests good the problem is the frequency isn't adjusting. I'm going to test the governor control unit as I have one on hand

    Mep805a voltage reg kit.

    All my part numbers match. I have no voltage at the output terminals. I Must have a different problem then. I will proceed to troubleshoot. Thank you for your help.
