Testing the CPS (3x and 18x signals) with multimeter

Recommended Posts

Posted (edited)

Today, I went out to check the grounding of the ICM...  I had left the pin through the CPS supply wire, the night before, so I thought I might check the voltage again.....  

Voila!  It now measured 10 volts...

So, then I thought I might check to see if it turned over...   I had not changed anything in regards to grounds, or anything else...

Yes, it started and ran -- a touch rough, but it ran and didn't stall out (I let it run until warm, then shut it down)....

Puzzling...

I think I'll replace the ICM and Coils with new ones, and see what happens then (I'll still check/clean  the grounds).....  

In any case, I don't think the CPS can be defective (or, maybe it still could be?)...

I've heard of people accidentally getting two of the seals between the ICM and the connector preventing the connector from pulling up far enough to make good connection on the pins. Might want to check that if you have been swapping ICMs.
