  • needing a test schematic for xmt 304

    High all new to site looking for a test schematic for main board on a xmt 304 serial # Kj074271. Got a bad switch plus I think a diode burned on the board. As soon as i turn it on it blows main breaker its wired up single phase also any help would b great! Thanks in advance

    Other than a occasional pulse transformer, the main board will not blow the breaker. More likely your input bridge (SR1) ,your output board and igbts are fizzled. Best look at them first.
