## Discrepancy

(CAN) WHEN CONDUCTING AN EMERGENCY POWER CHECK THE AC VOLT METER WENT FULL DEFLECTION TO 130 VOLTS.  NR 1 AND 2 AUTO TRANFORMER C/B POPPED AND CADC AC AND 26 VAC C/B'S POPPED. SHOP REPORT CONFIRMED THE FAULT THAT THE INVERTER WAS PUTTING OUT 155 VAC.  THIS WAS BELIEVED TO BE DUE TO POOR SOLDER CONNECTIONS WITHIN THE INTERNAL CIRCUIT BOARDS.
