SJM No Spark
Posted: Wed Nov 04, 2020 12:34 am
A bit miffed on this one.
Have an SJM I’ve worked on and I just can’t get a spark out of it. Replaced the villiers coil with a good one that reads 4.5K ohms secondary and 0.8 ohms primary and gives a good spark on another SJP. Removed the condenser and tested it at 0.23 micro Farads, right where it should be. Very clean baseplate and points box. Points clean and gapped properly. New HT lead and pickup/boot, good continuity on all bits. New spark plug properly gapped.
Any suggestions on next steps? I can’t think of what else to try! I’ve taken my time on this one and thought surely it would give a good spark today but no luck so far.
