Wiper Operation Question
When I started on my 62 Ford F-100 the wiper arms were removed. I recently switched wiper motors and having no reference to work by placed the motor linkage and the wiper arms based on looking and measuring. I have them working but there is something wrong with the park function. Could you please watch the attached video and tell me if they are working correctly and what I need to do to get the park setting right. I did the initial park adjustment at the half way point of the adjustment window.
A couple questions:
1. Do the arms look like they are oriented correctly?
2. Is the sweep distance about right?
3. Am I thinking right that the park function should make the arms go down at shut off and not up?
I've moved the arms (seems like about 100 times) to get the proper looking operation sweep.

The sweep looks fine, and yes the park function should stop them at the bottom (arm on motor points to the driver side). One thing that can cause them not to park is not having the motor and switch grounded together.

Been a while, but if memory is working today, I had to use the arm off the 66 motor on the late 70s motor that I used to set up the delay wipe. They were different but when I used the old one they parked correctly.
Hope my recall is good and this helps Mr oldJones

I see no indicated grounding point on the motor and assume the switch is grounded through the frame since there is no ground wire on the switch. This is a 2-speed motor and has 2 black wires coming out of the gearbox housing, screwed to a single screw. I'm wondering if they are ground wires and if I should attach a ground to them?

Thanks for the reply. The new motor came with it's own arm.

The arm is obviously not indexed correctly, and what John is saying sounds familiar to me as well. I had the newer motor in my '65 to get the intermittent myself. See if you can find a different arm. If I remember I'll try and dig up the one I took out of the '65 tomorrow and compare.

I have the arm from the original motor but the bracket s slightly different so I used the new one. Guess I could try it.

Update! I took the motor out twice and realigned per the instructions that came with the motor. The park still was going the wrong way so I did what any 10 year old would do and turned the motor to linkage arm 180 degrees. It works perfect now. Some times it's the simplest things...
