Component looks out of place

[Mike Watterson]

I've repaired fencers. That does look madly expensive and complex. Maybe it senses what voltage there is excessive leakage, and maybe senses damp and does it less often. I think I saw one with a neon firing the thyristor. It was otherwise like an early CDI out of a car. Looked like a car ignition coil too. The SM modules look mad.
