XMT 304 trips breaker!!

admin

I just picked up an XMT 304 in non working condition. The guy said it wouldn't power on, so the first thing I did was check wiring. The plug was wired incorrectly so I fixed that and tried the machine. Nothing. Then I tested the switch, it's fried.  Bypass the switch and use the circuit breaker for the switch.  It instantly trips the 30 amp breaker. It appears to have a new power board, but obviously something isn't right or isn't wired correctly. Any suggestions or does anyone have a technical manual PDF for this machine???
