If it trips the circuit breaker then its more than likely on the 240V side, so start at your plug and work your way through to the transformer.. from transformer onwards a fuse should handle the problem.
Thanks Gav, I'll start looking.
Bloody hell mate. Anyone would think you are about to have a meet or something with all the little niggley pinball problems you've been having.
Always the way isn't it, every time I think I've got some time to work on Kings of Steel something else goes wrong with one of my "working" machines. Who'd have thought problems some times occurs with these 20 year old boxes of wood and wire!
