RV Totally Stranded For 25 Hours...What Happened?? (My 96 Newell Coach Broke Down!)

What happens here

With the problem identified as a lack of 12V power to the ECM, the mechanic focuses on the ECM connector. He finds that the ignition wire within the connector has broken, causing the power interruption. To resolve this, he carefully pulls the damaged wire and connector pin out, then splices in a new ignition power wire and installs a new terminal pin into the ECM connector. After completing the wiring repair, the mechanic re-attempts to start the engine, and this time, it successfully fires up and runs smoothly, restoring full functionality to the RV.

Goal: Restore power to the ECM and achieve engine startup.

Tools and materials

  • ECM Connector — The electrical connector housing the damaged wire
  • New Electrical Wire — Splicing into the existing ignition circuit to restore power
  • New Terminal Pins — Replacing the broken pin in the ECM connector
  • RV Ignition — Used to start the engine after repair
  • Wire Strippers — Preparing wires for splicing and connecting

i'm not sure what to do about that so he was just digging through the connector to pull back to strip it and splice in a new wire and when he went to pull back it just broke like it just came off because it had already broken the loom like just forward of the pin and the connector that was most likely the problem um he's just going to put that back in there rig a wire up let's go ahead and kick that key back on all right and i want to check and see where i cut it if i've got power there if i can basically just run a new section of wire right there all right yeah he wants to bench test it just off of 12 volts off the battery just to make sure that's the problem and if it is then he's going to run over to engine places or whatever and get another pin to actually fix that wire the correct way and have it be done good tell you what he's johnny on the spot like just comes in here with his backpack just just doing it like i'm glad i made that facebook post i found this dude i'll just stay back here so whenever you're ready to give it a whack i can go back up there easier well that sounded like it worked oh cool i'm gonna try to go get a uh terminals everything we need to uh make the repair man get out of here apparently i didn't need a fuel pump man that's pretty common that people will uh misdiagnose ignition or battery power or ground for uh you know some sort of fuel system issue lesson learned i'm gonna start carrying uh multimeter and stuff like that with me so jeremy's back from the truck parts place they had to like they had to pay the freaking call out feed come back after hours let them in there but they actually got the uh the pins and he got a bunch of them so i could keep some as spares which is awesome and uh yeah he's back there now redoing that wire and that connector the right way so it's fixed permanently not some rigged up patch just to get me back once he fixes it it's good to go i shouldn't shouldn't have to mess with that particular wire again but that doesn't mean another one couldn't bust which is why i'm gonna keep these and uh some wire and multimeter all that stuff handy with me so i'm prepared for this in the future so it works from back there let's see if it does up here yep all those lights come on like they're supposed to and they should shut off in a couple seconds here then there we go we're in neutral liddy hey guys this is jeremy with jg diesel solutions mitchell had called me he's stuck on the side of the road with a series 60…
