You may have to bleed air out of the system to get it to work properly. Hope this helps.

97 350 .... 9 ft Western unimount isaramic . New 9 pin . Truck and plow side . New plow motor .new relays and solenoid . . Plug 9 pin in and plug power cord to to . Lights come on. Motor kicks in when I turn on the controller . But stays running and no movement. Test light the plow solenoid . All have power . New fluid. I'm buying a new pump for 200 hoping that's the problem . But I'm stumped on the new motor ...... Old motor had 1 post . Ground to frame . New motor has two posts . Post and neg to motor .... If I switch the ground back to plow frame like the old one. Nothing works but lights stay on . When I reconnect the ground back onto the motor . Lights go out and motor turns on. . Possibly blew relays? It's a new motor . Stumped

Try doing a flush and refill of the hydraulic pump AND the left-right cylinders.
The voltage drop is normal whenever the plow pump is straining.

e 60 snow plow we try to move it up an down to the left it goes to right any where you try to move it
