On my 63 J300. It's the basic Delco 2-speed used from 63 through the 70's on Jeeps and in th e60's on GMs.
There are three plugs on the wiper motor. I'll call them plugs A, B anc C.
Plug A is a single tab with a green wire. Plug B is a double tab with (from L to R) a blue wire and a red wire with a white tracer. Plug C is actually on the washer motor, and is a double tab with a yellow wire and a red wire with a white tracer. The washer motor works off the switch.
I bench tested the motor by running a hot to the red w/white tracer from plug B, and a ground to the blue wire from the same plug. Worked fine.
All installed, no go.
I have power at the switch, and at the motor. On both Lo and Hi. Power is always on at the red w/white tracer wire of Plug B, and is on at the other wires of plugs A and B depending what speed is on.
So I have power where I am supposed to have power. I'm guessing a ground issue? The tab I jumped with a ground for teh bench test gets power while in the truck, not sure what is going on there. I always thought the motors grounded via the strap on the lower left screw.
The wiring is in good shape, not butchered, and it came with the motor. I have is hooked into my 63 correctly, according to my FSM.
Any thoughts?
