Nice, good lookin out.

That adjustable resistor is used in conjuction with the "main" voltage dropping resistor to give me that 2nd speed. On high speed it's just the other resistor, on low speed it's both, and I can dial in the speed for the low fairly easily via the adjustment.

The heat is normal. That's exactly why you have to have high-wattage resistors, they'll burn up otherwise. That's why I have them hanging in the open there under the dash - better heat dissipation. They get hot because, basically, they are "burning" off half the voltage, leaving the other half for the wiper motor. I did not buy it from Radio Shack. I think it came from a place I used to work, we had a whole bunch of misc stuff around and that might have ended up with my stuff. You should be able to find them for sale from large electronics supply shops. I've seen them on ebay, like these 3 and 5 ohm varieties:

You need to be grounded at the switch where the escutcheon nut mounts at the dash. And the ground strip on the frame mount must be in contact with body. As the motor is braked by switching the current. If they are not grounded they will not turn off. They will only slow down a bit and run on after you turn off the switch. Then you have to pull wires to stop it. DL

Can anyone tell me what "ground connected" in the wiper switch diagram means? I assume that because the wiper system is ground isolated and the switch is just switching ground that it means the terminal is connected when the switch is in the on possition. I just want to make sure.

Thanks,

glutamodo, sorry about the mix up on drawings. Both were very helpful. I am going to give it a shot this weekend. I hope that no sparks fly!!

Thanks.

That's my diagram up there - not keith's. Wink

The resistors are not "colored" - they are high wattage ones, the little tiny ones you get at Radio shack will burn up in no time. Actually, one of them is a pair of high wattage resistors wired in parallel to achieve the resistance I wanted. The other is an adjustable resistor, which used so I could change it in winter time to get faster speeds out of it. This is what the variable one looks like:

The resistor values, the That diagram is in my Gallery on the Samba, and here is the caption that goes along with it:

keifernet, what color resistor did you use? I'm kinda diggin' the two speed set up.

Thanks,

See... "handy Andy" already had it all figured out and drawn up! Laughing

Nice work as usual bro... Very Happy

Pantone 149 were you able to find your drawings?

Thanks.

I recently went through the exact same thing. Got a 12 volt 67 motor and 2 speed 67 switch. I may have my notes staill at home. Will try to get you solid information tomorrow.

Does not mean you can't use it... use that diagram and hook it up so the motor runs on the firt click...

Yes I did, I guess. Kind of a novice, if you haven't noticed!! Thanks for the help.

Sounds like you may have gotten a later 2 speed switch?

jign4bass · Posted: Thu Sep 06, 2007 6:21 am Post subject: Windshield Wiper Switch Wiring

I ordered a new wiper switch for my 62 bug from WW. My wiper motor is 12v and has connections for 54d, 31b and 54. The switch has connections for 31(2ea.)., 31b, 53, 53a, 53b. My question is is what goes where?

Thanks as always,
Rob
