Step Action
1 Remove the J8 link on the rear of the Meter Alarm Panel (see Figure 3-16 for J8 location).
NOTE
This is the J8 on the rear of the Meter Alarm Panel itself, this is not connector J8 on the connector
bulkhead at the rear of the cabinet.
2 Verify that RECTIFIER OVERTEMP LED (red) is illuminated. Contacts on K1 and K2 change states
(K1 now closed and K2 open).
3 Verify that the LMF has reported an alarm condition. (BTS #26)

their normal states (K1 open and K2 closed).
