OK, so it looks as though it didn't blow the fuse which is somewhat strange but hey ho, back to tracking down the 8v sensor supply issue issueAll fuses on panel look good. Blower motor and A/C work
I guess that means it is somewhere in the wiring harness. And so much of it is not in halfway reasonable sight.OK, so it looks as though it didn't blow the fuse which is somewhat strange but hey ho, back to tracking down the 8v sensor supply issue issue
From my way of thinking I'd like to see the resistance readings confirmed using a different meter before condemning the harness.I guess that means it is somewhere in the wiring harness. And so much of it is not in halfway reasonable sight.
“….and replace ECM if can’t find problem.” Crazy crazy how this dozer just decided to throw codes and not move.In that case they are all showing open circuit, therefore greater than 5000 ohms, so they all class as "OK" on the resistance test.
Which is why IMHO you really needs a second hands-on opinion before shelling out for a replacement ECM that is probably priced somewhere North of $2k, plus labour to install.“….and replace ECM if can’t find problem.”
Any welding repairs been done on it recently.?Crazy crazy how this dozer just decided to throw codes and not move.
Nope. Only thing is a day before this happened I had a Cat mechanic replace the fuel pump and blow out fuel line to tank. Ran good for 30 minutes or so then started stalling out again like before line was cleaned out.Then next morning would not move. Makes me think a mouse chewed the wrong spot to have system be affected so quickly and overnight.Which is why IMHO you really needs a second hands-on opinion before shelling out for a replacement ECM that is probably priced somewhere North of $2k, plus labour to install.
