Unimount slow to raise/angle
Finally got to plow on friday. After a while ( couple of hours) plow is raising and angling slowly and drawing amp gauge way down.
I have a 98 gmc 1500, with dual batteris and a 100 amp alternator. Lifts and raises well at first but the longer I use it the slower it gets. Still works but, slow and draws more amps than I remember from last year.
I put a new motor on 3 years ago, pump has not been repalced since I've owned it for 5 years. Plow is approx 10-12 years old. Fluid was changed as well as the filter cleaned and is just leaking out of the fill check, connections were cleaned as well as I could. Wires "look" good. I'm thinking the motor is going. Could it be the pump? I do not want to just throw parts at it, but I am willing to put parts into it as it really owes me nothing. So how would I test the electric motor and pump in my driveway?
Sorry for the long post, trying to give as much info as I can.
Any ideas would be greatly appreciated.
