Combines l3 problems

Sounds to me like you might have some faulty wiring or sensors that aren't positioned right. If you have a test probe (a light bulb with a wire and an alligator clip) take that and open your fuse panel door and clip the wire to the chassis some where and test each side of every fuse. One side will always light and the other side should if the fuse is good. Start there and then check switches. Sometimes you get lucky and it's nothing more than a fuse that isn't making contact even though it looks ok, but this should give you a starting point. Curt

as to n1 improper cleanance, tab tooth off a collar sender, bad sender, bad connection, mouse damage to the harness, or bad module (unlikely more than one sensor area would be bad) as to n2 as posted before what changes speed is the pintle on a rack and pinion that throttles the oil to the pump. This is controlled by an electric motor which turns the pinion through a clutch on the early models. turn the key on, and have someone push the speed button and listen for the sound of the motor. It is easy to take apart and check. YOu can also take a battery with jumper cables and touch the wires to pos and neg then reverse the polarity to simulate what you are doing in the cab. IF the motor turns, make sure the clutch is not stripped or broke. You can manually turn the pinion to move the pintle down and thus slow down the speed.

Thank you I will try this as soon as the weather clears. Been raining for 2 days now. So we decided to go see the Twins beat the A's today. rrhead (SD)
