After repair, the regulator must be adjusted to
the desired voltage setting. Follow the
procedure under “Checking Voltage Regulator
Setting”. Slowly turn the adjusting screw full
range and observe the voltmeter to ensure that
the voltage is being controlled, then, while still

9. BATTERY EQUALIZER
VoltMaster Battery Equalizer Owner’s Manual
(100 amps) is annexed at the end of this
section.
Refer to “Electrical Compartments and Junction
Box” in this section, for location.
10. STARTER
Refer to Mitsubishi Electric Corporation

the end of this section for information and
maintenance instruction on MELCO 105P70
starter.
CAUTION
Prior to the installation of the Mitsubishi
starter, the Flywheel Ring Gear must be
examined for excess wear or damage.
Service Bulletin A1-M1N-1729EN included at
the end of Section 06 shows acceptable
levels of wear, and illustrates the proper
measuring procedure. Maximum wear is
0.5mm. Ring Gears with more than 0.5mm of
wear or damage must be replaced before
installing the new starter to prevent
engagement and/or disengagement problems.
Failure to do so will render the Warranty null
and void.
CAUTION
Do not engage starter for more than 15
seconds at a time. If engine does not start
within 15 seconds, release ignition key and let
starter cool for one minute before attempting
to restart.
11. ENGINE BLOCK HEATER
The vehicle may be equipped with an engine
immersion-type electric block heater to assist
cold weather starting. The heater male electric
plug is easily accessible through the engine
compartment R.H. side door (Fig. 39). To use it,
connect the female plug of an electrical
extension cord to the heater plug. The extension
cord must be plugged into a 110-120 V AC
power source only. The engine block heater
should be used whenever the vehicle is parked
for an extended period of time in cold weather
and a suitable power source is available.
11.1 MAINTENANCE
This heater is non-serviceable except for the
cord, and if faulty, must be replaced as a unit.
