    Looks like CR1 is bad. The part number for CR1 is 1N5406. It's a 3 amp 600 volt general purpose diode. Widely available for ~$0.50 each.

    OK, now we're narrowing down why you only get 5 volts at S1 2,4,6,8 & 3 when S1 is in Prime/Run. Since you always have 24 volts at both ends of CR1 then there is an issue with getting the 24 volts from CR1 to S1. Since you have 24 volts at S1 2,4,6,8 with S1 in the OFF and only 5 volts in the...

    ?? CR1 is a diode. It has no moving parts. I assume your may have meant K2? Please report back on the measurements suggested in post 13.

    It's possible CR1 is bad. Here is how to test for it. 1) Connect your meters negative lead to ground. There is a ground stud on the back wall of the cube to the lower right of the Voltage regulator. 2) Connect your meters positive to the right end of CR1. Check for ~24 volts DC there. CR1...

    Remember don't start it until you at least have the fuse mod installed. Does it turn over using the Dead Crank switch? Do you have ~+24 at S1 terminals 2,4,6&8 when S1 is in the PRIME/RUN position? Do you get ~+24 at S1 terminal 3 when S1 is in the PRIME/RUN position?

    It certainly won't have the MOV mod. That's a mod that I came up with a few years ago. PM me your mailing address and I'll mail you a MOV to install. No charge. Kurt

    Colt, I took some mechanical measurement's today on one of my 831's for you to compare your actuator and mechanical governor to. Measurements are shown below as measurement "A" and "B". "A" is the gap between the magnet and the target on the actuator arm as measured at the top of the two...

    MEP 831A Fix-up Thread

    The 802 one got "smoked" because you applied 24 volts directly across it's terminals. The 802 one needs a current limiting resistor with it. Without it you killed the 802 indicator LED. PM me your email address and I'll send you a version of the TM that has very clear schematics in it. You...

    MEP 831A Fix-up Thread

    With the set running you should see ~ 28 volts DC across the Hour Meter terminals. Terminal 1 should have ~24-28 volts DC on it when S1 is in the RUN position. Terminal 2 should have 0 volts DC on it with the contactor closed. Terminal 2 should have ~28 volts DC on it with S1 in RUN and the...

    MEP 831A Fix-up Thread

    Hmmm... Something still isn't right with the adjustments. The rod should never be able to lift itself out of the hole. The rod ball should always be in contact with the black lever when it's running or stopped. Never a gap between them when running or stopped. The ball lifting off the arm...

    Yes I had bare printed circuit boards built a while back, built up a few units sent unit out for beta test. Once beta testing was completed I had to re-spin the bare PCB design and received the new versions yesterday. Started populating the first one with components last night. Waiting on...

    Didn't know you were missing part of the housing. Looks like you'd need to order a complete housing assembly to get the lens that holds the bulb. Not cheap from DigiKey..$42 https://www.digikey.com/products/en?keywords=800-1030-0337-504 Also on ebay. Search for 800-1030-0337-504

    Ahhh... You're looking at the 2010 TM, I was looking at the 2005 TM. You are correct they call out a LED lamp in the 2010 version. The PN 98-19763 cross references to a Dialight PN 586-1102-005F. That bulbs spec are: T1 3/4 base, 28 V, Green, 520 nm Wavelength, 600 mcd brightness Looks like...

    The fan is a Rotron part number 031842. They are on ebay for $25. Also available on DigiKey and Allied Electric. The Contactor lamp is an incandescent bulb, not an LED. ** edit, it can be an LED or Incandescent
