Section 9 Generator Disassembly/Reassembly
9.1 Disassembly
In some installations, it is not possible to remove the
generator set from the craft.
Disconnect the external connections—battery cables
(negative lead first), AC-output leads in the controller,
remote start panel at the controller P3 connector, water
line at the seawater pump, fuel line at the fuel pump filter
inlet, and exhaust line at the mixing elbow. Observe all of
the safety precautions listed during the disassembly/
reassembly procedures.
Note: Because this manual covers several models, the
procedure for disassembly may vary because of
product updates and the assembly variations.
Disassembly Procedure
1. Place the start/stop switch in the STOP position.
2. Disconnect the generator set engine starting
battery, the negative (--) lead first.
3. Loosen the 4 screws and lift off the controller cover.
4. Disconnect the P4 (22-pin) connector from J4. See
Figure 9-1.
5. Remove the bolt and disconnect the ground strap.
See Figure 9-1.
Note: It is possible to connect the output leads in
various
positions for different voltage
configurations. Mark the leads for correct
reconnection.

4 from the circuit breaker and the neutral stud (L0).
7. Remove the 4 controller mount locknuts. See
Figure 9-2.
