Ultramount Plow Stops Moving

[dieselss]

Did you ck to make sure that the solenoid has gnd? The other little signal wire. Should be og/bk

[Junior MO]

Yes, it has ground and it is grounded to the negative side of the battery, along with the truck side harness and the electric salt spreader.

[dieselss]

Well if you got gnd,,,and signal.pwr I am inclinded to say solenoid....now make sure that all.the connectors are good,,,,even under the heat shrink. Then if there ok I would get a new solenoid

Just because you get power out on the motor with a test light doesn't mean the cable is carrying enough amps under load. I've had some similar issues and like previous ck under the shrink ends could be corrosion.

[Junior MO]

When the plow is running, I am getting 10.3 going to the right and 9.3 going to the left at the motor, if that makes since. I never thought about checking under the heat shrink so I will check that this evening.

Does the cable get hot?

[Junior MO]

Not hot, but they get warm. So does the motor. You can touch and handle just fine. No melting of the wires of outside sheath of the wires.

[dieselss]

Might be hot b/c of constant use. No cool down time

[Junior MO]

Plow if fixed! What we did was replace the Manifold Assembly (part #56610) due to corrosion inside the manifold. We figured that the rust inside the manifold was causing the relief valves to not act right when going to the left. We tried to just replace the relief valves, but they were froze to the manifold, so we just replaced the whole thing. Thanks for everyone's help!

[dieselss]

Glad to hear its fixed.

So the motor must have been running but the plow wasn't moving correct?

[Junior MO]

Sometimes it would and sometimes it would not. It was never consistent either way.
