To Start From the Rear:
• Turn ignition key to ON.
• Move rocker switch to REAR.
• Ensure everything is clear of rotating parts.
• Press the switch to START.
• Moving switch to the center OFF position
will turn engine OFF.
• Return switch to FRONT for normal operation.
• Return the switch to FRONT run after use. If the
motorhome will not start from the front, try to start it from
the rear start box.
CAUTION: When checking the engine compartment this
switch should be placed in the rear start position. This will
prevent accidental starting of the engine from the cab area.
The Leece-Neville alternator with integral rectifier and regulator and
remote voltage sensor is designed for reliable high output at all RPMs. This
alternator offers high output over a broad range of operating speeds. The
4884JB deliver the same reliable, heavy duty performance all Leece-Neville
alternators are known for. The 4884JB features an integral regulator and rectifi-
er for compact installations. While driving, if you notice that your tachometer
is not operating, you may want to have your alternator checked. The tachome-
ter is wired to the stator terminal of the alternator. Always keep a close eye on
the voltmeter in the dash area.
The alternator should replace the amper-hours taken from the battery at
start. The amount of charge given to a battery is dependent on engine run time.
This allows to maintain a 75% level with enough energy to power the electrical
systems. Driving the motorhome for a short distance or short periods of time,
may prevent the battery from being brought up to above 75% level.
Specifications:
• The integral rectifier system utilizes 12: 50-amp diodes
mounted in multiple aluminum heat sinks for efficient
heat dissipation during high-output operation.
• Aluminum housings
• Bi-directional fan
• Front bearing: 305 cartridge type
• Enclosed brush system
• Operation Ambient Temperature Range (-40º to 200ºF)
• Negative Ground Configuration
• Regulator Adjustment Range 13.6 to 15.4 Volts
• Batteries may start to gas at 14.3 Volts
• Max. Operating RPM 8,000
