450B dozer hour meter

Does anyone know where the positive wire for the hour meter connects on the dozer? Mine stopped working and I want to find its terminus.
Thank you.

Mine stopped working too. But is was the meter not the 12v source that failed.
I'm not sure but it would have to be a 12vdc source that is turned on by the the ignition switch. I don't know how the hour meter 12v source knows the engine is running. Maybe the same 12v source as the injection pump fuel solenoid ??
You will have to find someone with a wiring diagram to be absolutely sure.

I was hoping it was in the tech manual, but it wasn't. I may have broken loose a wire when I was replacing the fuel filters and that may be it, but I'm not sure where it connected.
