Test 1: Input Battery to Input Return—Use the following procedure:
1. Connect one test probe to the A bus BATT input power terminal and the other test probe to
the A bus RTN input power terminal (Figure 7).
Figure 7. Test 1: Input Battery to Input Return
2. Verify that no continuity exists between the BATT input and RTN input terminals.
3. Repeat the test procedure for the B bus.
Test 2: Input Battery to Output Battery—Use the following procedure (Figure 8):
1. Starting on the A bus, at the output terminal for circuit 1, connect the negative test probe to
the bus A input BATT power terminal and the positive test probe to bus A output BATT
power terminal for the circuit being tested.

2. Turn on circuit breaker A1.
3. Verify that continuity exists between the specified terminals.
4. Repeat the test procedure for each remaining circuit (A 2-7, B 1-7).
