    I did a search,the best I found was the double r video a few months ago-lots of work put into it! nice job!.I have a few 147,148 switches I removed in the 80's and had stashed.I am wondering if there is a way to test them with a ohm meter? They worked when removed but after 40 years of sitting in box who knows.I don't want to sell something that won't work/disappoint someone.I do not have a motor to play with,is there an easy way to Ohm it out or test with a test light? Thanks in advance Steve!!

    What years did they come out of? Once you get them tested Steve, I may get one from you.

    I don't think much could go wrong with them, as they are just metal contacts that can easily be cleaned, no real electronics, if you know what I mean

    Just a continuity test would do it.

    The recessed park came out of a 73, the non recessed a 74,I see a few people looking for them so I don't know if they commonly fail? My 72 is original,but I probably used the wipers 6-12 times in 27 years.
    I don't know which terminals are which,and they both have 4 terminals [wouldn't the recessed park have more terminals???] I just don't want to stick somebody with a POS/DOA item,I'm not that way! Thanks guys Steve!!
