Howdy chaps,
If you search electronic ignition here or at Caimag, I covered this one before. Modern point applications assume much higher rpm, multiple points cams and assumption the points block will be running on mirror hard chromed finish on said points cam, therefore spring tensions are set high and rapid wear can be an issue.
Hall sensor like as units as in Clyde Crouch’s are nearly bullet proof with minimal accommodation. Their longevity can be ensured for a fastidious owner only by fusing them. The primitive thermally activated HD sourced circuit breakers commonly seen at the battery ground strap connection to the back of the trans case flange on Indians are unacceptable for electronics, and I would even say for a now fragile 75 year old auto lite generator. If one isn’t inclined to fuse the whole system at 10-15 amps then at least install an inline 10 amp mini fuse under the full tank where the power source for the sensor exits the ignition wire tube.
Nothing lasts forever, after 20 plus years in four different machines without a hint of problems when inquiring with Clyde at the donkey barn in March about whether I might just replace the more often used ones as a precaution he mentioned potential failure would be linked to heat. That is a valid concern with my Knuckle with its timer tucked in by the exhaust header but Chiefs, running theirs out in the wind, operate far cooler.
