the rear of the circuit breaker and the components mounted
on the bracket.
DC Output
Circuit Breaker
(CBA1)
1. Remove the bracket per “CBA1 Bracket Assembly” in this
section.
2. Remove the cable from the top terminal of CBA1 by
opening the bolted connection. (The bottom output BATT
cable should have already been disconnected and taped per
“Disconnecting a Rectifier” in this section.
3. Remove the two quick-disconnect connectors from the rear
of CBA1 (pull straight out).
4. In the front, free CBA1 by removing the two screws that
hold CBA1 to its bracket.
DC Inductor (L2)
1. Perform the instructions in “CBA1 Bracket Assembly” in
this section to move the CBA1 bracket out of the way.
2. Disconnect the cables from the inner and outer tabs of L2.
While doing this, small flyback diodes (CR3 and CR4
with red and blue leads) and their mounting tabs will also
come off the inner and outer L2 tabs. Note their positions
for proper subsequent reassembly.
3. Remove both of the left-side mounting nuts of L2. While
supporting the weight (approximately 30 lbs.) of L2,
loosen both of the right-side nuts and slide L2 to the left
until it is free.
4. Remember to remount CR3 (red lead) and CR4 (blue lead)
tabs during reassembly.
DC Filter
Capacitors
