New to site. We added a snow & ice division this year to our services. Bought some new and used boss v plows. I have one with an electrical issue. The v plow stays in the down position or up positions and wont move. Hydraulics are fine.... pump & motor are solid. Hydraulic fluid is fine. Plow lights sometimes work and sometimes don't. It'll work fine for an hour or hours on end.... but when my guy dropped the plow down the other day.... he couldn't get it back up. The solenoid for the plow has been replaced.... if we jump point to point... the motor will run and the controller will control the plow fine. But the plow lights still don't work. If we dont jump point to point on the solenoid.... the controller will not control the plow at all. It's a boss rt3 v plow with sl2 lights. Please help!
