Bench Testing a Wiper Switch

[dbevans2249]

I need some help bench testing wiper switches.

I have searched the forums and read all I found but no joy, also I cant blow up the diagram Viperwolf posts and read any of it. It is just a blur and I might not understand it that well anyway.

I have 2 delay switches and 1 regular switch. I have tried checking with an ohm meter but dont get the results I need or expected.

The regular switch was working fine so I dont see why I cant get any continuity from terminal 2 to 5 or 7. I get continuity from 2 to 1 with it in the off position as I believe it should.

The two delay switches have continuity from 2 to 1 in the off and on position's. I get continuity between two other terminals with the switch on but not from 2 to any terminal but 1.

Can anyone tell me what terminal should have continuity to what in the different switch positions? Also how many hot wires go to the wiper motor on high and low speeds.

Thanks Dave

It has been a while but as i remember all 4 wires going to the wiper motor will read positive at diffrent times. I think the black wire is the park wire and it will read positive until the wiper arm reaches the correct park spot then it sends a ground back to the switch to stop the wipers in the correct spot. Hope this helps.

ck out wildhorses. they have a good pdf file on their wiper motor switch.

Thanks for the answers but I still want to be able to bench test these switches with a multimeter.

I will try testing a 7 wire switch again tomorrow. It may be that I did not understand how the delay switch functiones that was part of the problem. Now I know it is; Delay, off, low and then high. I will also test with a jumper from terminals 2 to 4 hooked up and see if that works.

If anyone knows how a bench test on these wiper switches should be done I sure would like to hear about it. Thanks Dave

This should be the stock switch.

Viperwolf, thanks. I had this one before but could not use it. I think the problem was that I saved it with out clicking on it to enlarge it first. Then when I tried to use it, it got all fuzzy and I could not read it. I have it now and it works fine, I will use it to test things out tomorrow.
