No since the op's machine works in 120, but not in 230, I'm thinking something is allowing the strike relay to come on and stay on. I'm going with a primary ground issue. Easily tested by disconnecting it temporarily. Reason why I think this is that the unit did work properly for some time, I'm wondering if something was improperly hooked into that panel and supplying a low voltage to that ground circuit, and into the commons on the board. Now most of the commons are isolated, strike isn't.
