So I guess at one time or another the switch on the turn signal failed. They installed another one on the dash. I had seen it and tried it but still no joy.Fuses checked good. Applied DC power to motor via jumper leads. pump worked like gang busters. Yes I did get wet lying under neath the front end. After that the switch on dashboard worked fine. Switch on turn signal still inop. Guess the motor just needed some shock treatment. All is well on the motorhome front.
Thanks to everyone for their input and time.
