Do you have voltage across the solenoid when you hit the power button?"clicking" does not automatically mean the solenoid is good.

Direct power to motor and see if it runs.

The motor does run but it has a weird kind of sound to it. I took it off and the inside smell burnt
The name brand says Monarch on the side so i called a local starter rebuilder guy and he says he has one on the shelf.
Hopefully this solves the issue
Guy's thanks for the help

I put a test light on the solenoid when we pressed the up button and we have juice.
Then i put my multimeter on it and it said 10.5 volts

If the motor runs there's juice flowing through the solenoid. What do you have for voltage on the input side of the solenoid? You shouldn't see a significant drop through the solenoid. If the volts are low on the input side too, make sure the cable ends are clean and corrosion free. Low voltage will burn a motor up.

I have a monarch pump on my dump body. You can test and get voltage, but you may be lacking in amps, that is, not a good current flow. Low amps will burn the motor, just like low voltage.

Try first thing running a jumper cable to put a heavy duty ground right to the motor body. The motor depends on good contact between the body and the frame of the truck. Corrosion or even oil if you sprayed the under body will reduce the contact. I can spray mine and the next day it won't go up or runs so slowly I know it will burn.

To fix that, remove the motor and clean the contact points (scrape and clean, add dielectric grease, maybe wrap some 12ga bare copper wire at the bolts/bolt holes).

There are filters in the fluid reservoir that need to be cleaned for good flow. Make sure the fluid is clean, cheap to replace it while you are in there.
