Battery-Powered Systems Installation Guidelines
TESTING THE ALTERNATOR
Alternator voltage test. Connect the test leads of
a volt meter to the alternator output terminals. Note:
Most Leece Neville alternators have isolated
ground rectication. Always connect tester/volt
meter directly to the negative output terminal of
the alternator or your test will be inaccurate.
• Start engine, increase to high idle (1500
RPM): The volt meter should now indicate that
the alternator output voltage has increased to
a range from 13.8 volts to 14.2 volts. (Ensure
that all electrical accessories of the vehicle are
in the off position.) If voltage increases but is
out of range, inspect to see if the alternator has
an adjustable regulator. If so, reduce engine
speed to idle and adjust voltage to a setting of
14.0 volts. If voltage is higher than 14.7 volts
and cannot be adjusted below 14.25 volts, or if
voltage is lower than 13.8 volts and cannot be
adjusted into range, then replace the alternator.
For more information, please reference Leece-
Neville Technical Publication, TSB-1019.
WIRING THE "IGNITION INTERLOCK" ON THE
HVAC UNIT
• If your HVAC is provided with an “Ignition
Interlock” cable, then follow these steps to
properly connect it.
1. Connect the white wire from the “Ignition
Interlock” cable to the “ON" position of the
key switch. Here are some suggestions:
• Volvo - in the sleeper control panel
cabling - wire F60A1-08
• FTL Cascadia - wire under passenger
dash to connector X-6 of the SAM-Cab,
pin #10
• International Prostar - pink wire labeled
"A13EE" in the driver's side luggage
box.
2. Connect the black wire from the “Ignition
Interlock” cable to grounded, metal chassis
connection.
• Start the HVAC unit. Turn the key to the “ACC”
position. If the HVAC turns off when the ignition
is in the “ACC” position, you need to revise your
connection. Use a voltmeter to ensure that your
connection point allows for power ONLY when
the keyswitch is in the 'ON' position.
WIRING THE 120VAC POWER TO THE HVAC
UNIT
Follow the directions and wiring diagrams in your air
conditioner installation manual.
The connection of the 120VAC cable to the inverter
should be done with either the extension cable
or the Y-cable assembly. Dielectric grease should
be applied to any connections outside of the cab
structure. “Splicing” outside of the cab without taking
precautions for waterproong is not permissible and
may void your warranty.
Only as many extensions as required should be used.
Cables should be routed and clipped securely so as
to prevent chang and rubbing.
The connection at the HVAC unit should be done with
the supplied plug.
