Wiper motor wiring

[dgrinnan]

I have an original electric wiper motor in my 47 WC 1/2 ton.  All the wiring was pulled out when I got the truck.  I only see one external connection  I am assuming this is the power supply and the ground is through the body of the motor and connection to the cab.  Can somone confirm?  I also don't see how I am suppose to make the wiring connection.  The connector sticking out of the side of the motor is not threaded.  At first I thought a wire would be terminated on that connector with a screw. Is it just a push in bullet connector?  Can someone pull the cover off take a picture of the motor?

That small split would leave me to believe it is a bullet connector, that is exactly the kind of connector that is on the interior light in the truck I just picked up last Friday.

Not being at home I cannot measure and give you an indication of the size of the bullet connector used on the interior light.

I do think you're on the right track though.

I believe you are right also and it's a bullet connection. I have a few motors but none are installed in a truck.

Thanks. I have a tray of various size bullet connectors.  I will see if one fits and then test the motor before re-installing it.

were electric wipers an option?

[dgrinnan]

Someone must have upgraded years ago. The motors are old and electric but the manual refers to vacuum motor.

Yes at least towards the end of the series they were available.

I thought they were original.

Good background info on wipers as they pertain to the 39-47 trucks. Click on the link to read the full write-up unless you just like to look at the picture.

I think I've got a full set of those sitting here. The tricky part is they require an additional hole so it's not easy to revert back if you needed to

[dgrinnan]

Thanks, I have both electric motors.
