I noticed an earlier post where you stated your negative opinions about converting these sets to single phase which I chose to ignore. In viewing this one however, you didn't just address the process but went much further to libel a fellow SS member with some downright derogatory remarks. I...

More bad (& confusing news)....now not getting any voltage at L1 & L3. No more under freq light (changed out fault panel). Next swap out will be a speed switch. Still confused about the strange DC voltage on the transducer. The set I installed showed no difference as far as display but I...

Steve, Went out to start unit up & noticed under freq fault light on. Started up unit & the light would not clear after start-up. Set rpm with an external tach & closed main breaker & measured voltage at L1 & L3 at 120.3v. Checked frequency with an external meter & got 60.5 hz. While...

Jim, I did find one of the lugs on the board that was not 100% tight when I started to back it out for identifying all the connected wires. When I put everything back in place I verified all connections were tight. Hopefully the slightly loose caused the problem with the frequency meter...

Steve, Just got inside from re-checking the recon board wiring. Didn't start it up after checking with it being so late. I'll go through your checklist on Friday. I'll be happy if I have a bad transducer or freq meter. The meter pegging to the lower left side really threw me off. This...

Captain--now it's my turn in the tank....I just completed a single phase mod on another MEP-004A and after checking all the wiring changes & installing the resistors on the CTs, I cranked it up & right away noticed the freq meter "pegged" downward to the left. Checked L1 & L3 and got 120v at...

Captain, I can't offer much help on this one as will soon be occupied for several months. If Sewerzuk could weigh in, he could probably help us out. I'm thinking he's busy somewhere as well--seems he too has been a little "scarce" for quite awhile. Good luck with everything. Kevin

Captain, IIRC, a defective speed switch could be causing the field not to be flashed. This could be one of those coincidence failures (or murphy's law in action). I have an ASK model I'm building for my brother & it is doing the same thing as yours. I found a missing pin on the wiring...

Captain, It might help if you could do a few sketches with each wiring connection shown with some descriptive text for each one. Maybe some photos would help as well. Also, since this unit is obviously in a running condition (with all other mechanical & electrical functioning), I definitely...

Captain, Just trying to learn something here, but I wanted to ask why you "unbonded ground from the back of the neutral lug"? Is this something you did on the generator itself or something in your house panel? Hopefully some time this year, we'll be connecting our MEP4 to our house so I need...

Captain, For all the wiring changes (jumper & instrumentation wire moves) I've been doing on the underside of the board. The generator used in original video from Zewerzuk has the bus bar on the upper side of the board. Also, on all 3 units that I converted, the bus bar was on the underside...

Hi Matt, I've just completed my third single phase conversion on an MEP-004A and wanted to ask about the voltage differences on the two legs. As with the prior two sets I did, L1 & L3 voltages are not both the same. In today's test for example, L1 was showing 113 volts & L3 was showing 126...

Steve, On the MEP4s I've been setting up, I apply a marks-a-lot (or thick point sharpie) line on the throttle control shaft once the unit's speed is set for 60-hz output. This provides a quick means to set the unit for a cold-start throttle position. You will still need to make minor...

Out of curiosity, I have to ask: What is your application in which a 60KW unit is needed in single phase mode? I plan to set up either an MEP-004A or maybe an 005A unit whenever I get my large shop built, but plan to leave the unit 3-phase so I can install some 3-phase equipment. Haven't...

Copy--I'll go with the 39 ohm/25 watt, unless I can locate one in the 15-20 watt range. Thanks for the reply & looking forward to finishing the job....now if I can just get moving on our 38 KW load cell... Thanks again & don't forget to let us know if you make it to the FL panhandle or...

I'm about to order the resistors for the CTs (enough to do several MEP4s) and wanted to clarify the wattage rating needed. I see someone else had 40 ohm 25 watt resistors. You mentioned any size between 38 & 50 ohm but it wasn't clear which wattage rating you ended up with. Also, you...

I saw that photo but didn't realize there were three resistors installed....now I can see the third green wire you added in the right side of the photo. Thanks again for the assist! :)

Sewerzuk--Just successfully (no smoke or stray sparks :) ) completed my first phase conversion on an MEP004A. I would like to continue with the current transformer mod but can't seem to locate the post that contains the final configuration of the resistors. I see where you noted 38-40 Ohm...

Thanks for the clarification--that's what I figured but just wanted to sure. Now I've reached a minor "all-stop". Got the bus bar off & cut between T11 & T12...reinstalled bus bar, reconnected T13 wire, T10 wire and then began looking at T11 for the original wire connection & then to connect...

Calling decodeme2 & sewerzuk for assist! Hi Kevin, I am setting up to do the single phase conversion on an MEP004A. Sewerzuk's video states to connect the jumper wire from [by description] the T12 ("right rear" of the board where the copper bus bar section has been removed) to # T2. In your...
