I have a JD 4240 that I had to replace the right hand windshield wiper motor with a new motor that replaces the OEM motor that is no longer made. The old motor had only 3 leads (low speed, high speed, and ground). The new "universal jd" motor has 5 leads which appear to be low speed, high speed, park, washer mode, and ground.
Connected new motor to the low, high and ground leads from the tractor. Left the other two leads on the motor alone.
My problem is that if I turn the switch on, nothing happens, however, if I turn the key off, turn the switch on, then turn the key on, the wiper will operate normally.
I can also have the key and switch on and disconnect the lead at the wiper motor and motor will start and operate normally.
I am of the opinion that the circuit breaker on the switch is tripping when the switch is turned on.
It seems to me that if the motor start load is too much for the circuit breaker, it should trip all the time, not just from turning the wiper switch on.
There were no instructions with the new wiper motor, so I am hesitant to replace the switch, without knowing whether I needed to have wired the motor differently from what the old motor was.
I am the third owner of this tractor and it is obvious the wiring under the dash and under the cab are far from original.
What I am confused about is why wiper motor will operate normally if the switch is turned on before power is applied to the motor, but not if the wiper switch is used to supply the power?

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
