Is that the one for the UF light? I'll check it out this weekend. Will be out of touch a few days... Thanks

Do have an IR thermometer. Have mainly used it for checking engine temp, exhaust & injectors & generator bearings, but will try it for checking cables & connections too. Good idea! :) Thanks, Kevin

You must have missed my earlier post, but when I swapped-out the existing [leaking] TWC with a "suspected good one", there was no correction to the UF light remaining on. After a wiring harness swap (with no fix) I then swapped out the fault indicator assembly. That cleared the problem so...

Yes it's good having another unit nearby, but eventually, I do want to get it back together too. The engine looks real clean but when I got it in I found cut wiring harnesses & a couple missing switches. Overall it's a decent looking unit. But in this case, yes the spare parts nearby...

Brian (& others who have an interest) Never got around to checking the P31 cap. Tested the Start/Run/Stop switch IAW TM and all open & closed circuits checked out. Then swapped out the wiring harness coming from the fault indicator panel. That did nothing. Then swapped out fault indicator...

Brian, I'll check P31 Sunday evening. On whether the UF light goes out when the battle short switch is turned on, I can't say for sure but I almost seem to recall the UF light did not go out, but will add that to the list for a re-check. I'll also check each wire # connected to the S/S/R...

Thanks--since I have a "donor" MEP-004A on hand I'm somewhat confident that the replacement TWC should be a match. Haven't checked the wire connections from one unit to another but expect no differences. Hadn't figured on contacting the Clearwater folks. On the replacement ratio you...

Brian, Lit off the unit this morning and at first the UF light did not come on. After about 5 minutes of running it will light up. I can hit reset and clear the light for another 5 minutes or so of running & then it will come back on again...I can repeat this over and over with same results...

Maybe that's why I couldn't locate relay K12, though I didn't spend much looking time being it was so late. Still doesn't seem logical that they would install the wiring, lights & possibly relays "just because"...could be it's cheaper for standardization of components and then they could just...

Peter, I did test both freq & voltage at L1, L2 & L3 with an Extech MA220--my "good" meter since I can't afford a Fluke. Also don't own a Kill-a-watt meter. And from what I can tell in the TM, the utility sets do monitor freq, but they don't have the 50/60hz switch. Otherwise I would think...

OK for the few of you who work on the water-cooled models, I just did a "1st for me" light-off for this unit & I've got an under-frequency indication but freq meter is reading 60 hz. Tried to reset several times, but no change. Closed the AC breaker and tested voltage & frequency at L1, L2 &...
