3. Repair is straightforward.
a. MOTOR: check and/or replace fuse, remove faulty
motor or faulty trigger (switch, relay), install new
motor or trigger, test motor. For further information,
see the applicable section in this manual.
b. SOLENOID VALVE: check and/or replace fuse,
remove faulty valve or solenoid, install new valve or
solenoid, fill fluid system, test valve.
c. RCL: check and/or replace fuse, repair per RCL
manual, test per RCL manual.
d. ROTATION INDICATOR: check and/or replace fuse,
remove driver assembly or sensor, install driver
assembly or sensor, test thumper. For further
information on rotation indicator, see Hoist Drum
Indicator System, page 5-10 or the applicable SM
package.

Alternator Replacement

NOTE: On cranes with air conditioning it may be
necessary to move the compressor to gain access
to the alternator.
Removal
CAUTION
To prevent damage to electronics, in order: Ensure
keyswitch has been off 2 minutes, Battery disconnect is in
the off position, Remove ECM power fuse, Remove
negative cables, Remove positive cables (if required).
1. Turn the ignition switch off two minutes before
proceeding to the next step.
2. Turn the battery disconnect switch to OFF.
3. Remove the ECM power fuse.
4. Disconnect the batteries starting with the negative
terminals.
5. Open the engine compartment.
