    MigMaster 250 blowing fuses

    Was using it and just stopped feeding/power output. Contactor won't suck in. Nothing happens when trigger is pulled This happened suddenly. Went to replace fuse and it pops as soon as it is put in with nothing going on. It popped as soon as it was pushed into the holder. I didn't even have time to tighten it. Any ideas? Been a flawless machine up till now since 2001.

    In that case, BR1 would probably be a good place to start.
