Hello all looking for some help with a new to me MEP 802a. Put some fresh batteries in it and she started right up and all options functioned properly.
I had to replace a few parts due to some rodent urine corroding terminals and now K1 will not close as well as i believe the circuit interrupter and battle short light have burned out as well. i have documented pictures an will post a TLDR with bullet points after this paragraph.
TB3 was rotted due to rodents and was replaced with a new block. The glow plug relay was also in bad shape so i replaced that one as well with a generic 24v solenoid. the starter circuit solenoid located next to K1 was replaced due to a broken stud for X2. All wires were labled and pictures taken before disassembly. I have recently tested K1 per the TM by jumping A1 from starter circuit solenoid to X on the K1 interrupter. When the test was performed the switch for the interrupter worked perfectly fine. One more thing to note is the fuel gauge will now peg to full insted of reading the 1/2 ish tank level it has been. some times it will start to read properly. There is no visible broken or chewed wire that i have been able to locate thus far.
TLDR:
-Genset ran, made power, power to lugs, before repairs.
-replace TB3 from rotted terminals, labled and double checked the numbers on wires.
-replace glow plug relay due to corrosion
-replaced starter circuit solenoid (white in picture is old black in picture is NOS from green mountain generator)
-Engine starts, runs makes power to inlet side of k1, when trying to close (holding button or turning on Battle Short) both indicator lights went from bright green to orange to red to no illumination)
-K1 will not close (tested per TM and will work when jumped per TM with "key" in off position)
-power does show on ac voltage guages as well as reads with multimeter on A1 B1 C1 side
Thank you in advance im sure someone is going to look at this and know immediately what the heck happend here.
