moran75 Posted August 5, 2022 Share Posted August 5, 2022 Hi all its been a long day - can’t think straight ! re attached which is self explanatory …before and after pressing on the switch ….so switch is broke with fluctuation /high continuity reading like that? thanks in advance kev Link to comment Share on other sites More sharing options...
crowvet Posted August 5, 2022 Share Posted August 5, 2022 Looks good to me, with the switch open, you have near 0 continuity. With switch closed you have 31.2 ohm to complete the circuit. I could be wrong? but that seems reasonable to me. Link to comment Share on other sites More sharing options...
EmTee Posted August 5, 2022 Share Posted August 5, 2022 Yes, the switch seems to be working. I'm not sure about the 31 Ohms, but it could be intentional to limit the current to less than 0.5 Amps. Link to comment Share on other sites More sharing options...
moran75 Posted August 5, 2022 Author Share Posted August 5, 2022 Thanks all Aha…was expecting reading to move from 1 to close to zero? Like when you touch the two probes together? by the way have I set multimeter to correct ohms - 200? when I see set to 2k /20k I do get thr reading of near zero after all?… many thanks for help kev Link to comment Share on other sites More sharing options...
JZRIV Posted August 6, 2022 Share Posted August 6, 2022 31 ohms is bad with switch closed. Should be less than 1 ohm preferably. 1 Link to comment Share on other sites More sharing options...
EmTee Posted August 6, 2022 Share Posted August 6, 2022 Is this the same switch...? https://forums.aaca.org/topic/382746-micro-switch-for-transmission-stator/#comment-2407873 1 Link to comment Share on other sites More sharing options...

In the photos I had meter set to 200 ohms - and was expecting a near zero reading but got the variable high reading as per pic.. but at setting 2k or higher I did get a near zero reading and when used the ‘beep’ setting on the multimeter (which i since found is maybe best way to test continuity?) I did get the beep so maybe I had multimeter set wrong in the first instance ?…and switch ok? cheers kev Link to comment Share on other sites More sharing options...

telriv Posted August 6, 2022 Share Posted August 6, 2022 IF you get the switch from Loren it's almost guaranteed to be good. He DOESN'T sell junk. Tom T. 1 Link to comment Share on other sites More sharing options...
moran75 Posted August 7, 2022 Author Share Posted August 7, 2022 Good news as an update , and in case this thread is stumbled upon in the future.. In a nutshell : 1)after my original late night post, a test light in the morning did light up when connected, but very very faintly…whilst in the car switch didn’t seem to light up at all, hence it’s removal . so the audible beep on multimeter proved continuity, but not ‘enough’ If that’s a technical term😀 2)the metal ‘trigger’ across the top was rusty, not massively. Cleaned with wire wool and contact cleaner. 3) now test light slows bright … and when connected to multi meter at lowers ohm setting (200) switch rates close to zero when pressed so hey presto switch is now good i had erratic operation at idle, which reduced to almost non existent, even with adjusting whilst on car …hence digging deep thanks all kev Link to comment Share on other sites More sharing options...

I should edit the post. I failed to make a note of that. The switch has been test and is good. I re-enforced the bottom area because it is a weak spot from day one. Can't recall how many of those switches I have thrown away because the metal part was broken off and gone. Thank you, Tom, for the vote of confidence. lol Kev and others looking at this. In my automotive tech electrical classes way back when we were taught to use the lowest setting on the meter and in the case of doing a continuity test. You are allowed 0.1-ohm resistance per connection. So, your reading is fine at 0.3 max. Loren 1 Link to comment Share on other sites More sharing options...
