cisgww,
To me, crossing over the solenoid means jumping from the big BATT connection lug to the START post on the solenoid.
If you have any lights on the rig..as you mentioned you do, it means the battery is functioning, and tied to this common post on the starter. If this is true, and you mechanically jump from this same BATT connection to the solenoid START post with no activity, that would tell me the solenoid is bad.
This would not cause the the truck just to stop though. Did the truck actually have a snow plow on the front. Is this plow positioned with a small hydraulic electric pump. Is this plow connected to the battery or some major junction block and does the rig only have one battery.
I would tend to tie the plowing in with the loss of electrical...maybe the plow is protected by a large circuit breaker inside the engine compartment, and some of the start function of the truck and on this leg too.
The kicker is your statement about jumping the solenoid. If there is battery power to the starter and you stick your screwdriver across this big post and the small solenoid ( the correct one )post, it will turn over!
