I can't remember the amount of confusion it caused, no doubt my opto couplers and silicon 30V switches came into suspicion but finally the magnet was top suspect. I had in mind that heat cold or knocks can destroy a PM, making it a TM temporary magnet really.
I took a ride over to a Ham in Rushden who had a grave yard and a replacement did the job.
