I have been troubleshooting my Trailblazer 251 after it was jump started (didn't know this was bad until after) and the weld output stopped working. I have narrow it down to a bad PC2. Does anyone know where I can download or buy the schematic for the board? It looks like RV1 (the red circular component in the photos) was the only component to fail before the connector to the board melted (disconnecting power to the board). Serial number KG251929
