XMT 300 won't strike an arc

[Adam McLaughlin]

Hi Guys

I have an early ( 1990 ) XMT 300 that won't strike an arc
Initial examination shows that the LEM board has a burned cap on it
I lost this board on my Synchro 250 when I got it, and changing this board fixed up the machine

Anyone have any experience with these? Any ideas where to start?
Was hoping that someone on board had any experience fixing these things up

Lemme know

Can't link photos from google pics for some reason?

No better place to start than by replacing the charred board... Check and see if anything else got smoked, if so, change that too.
