## Discrepancy

(CAN) ARRIVING AT GATE PILOT WAS ALERTED BY "BATTERY TEMP MONITOR" ANNUNCIATOR FOR MAIN AND AUXILIARY BATTERY HOT. THIS WAS FOLLOWED BY A BIT OF SMOKE FROM THE MONITOR. INVESTIGATION REVEALED THAT THE MONITOR WAS BURNT OUT. ALSO NOTED THAT SENSOR OVERHEAT P/N 71867 OF THE AUXILIARY BATTERY WAS SHORTED TO ITS MOUNTING TERMINAL PRODUCING A VOLTAGE OF 18 TO 20 VDC ON PIN B OF CONNECTOR 2433P1. REF. WIRING DIAGRAM 24-32-11.
