1965 idle stator …continuity …minds a moosh


Recommended Posts

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

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.

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.

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

31 ohms is bad with switch closed. Should be less than 1 ohm preferably.

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..




at setting 2k or higher I did get a near zero reading 




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?

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

Looks to be visually …maybe in market for a replacement 😀

Same switch, just a salvaged part from one of the many cars I have had over 40 + years. 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.
