manual reset circuit breaker or fuse ( FIG 3-E).
2. Connect the controller to the battery through 2 AWG wire ( FIG 3-N).
3. Terminate 2 AWG wire ( FIG 5-A) power wire to controller through a
2 AWG 1/4” ID ring terminal ( FIG 5-B)
4. Attach ring terminal to controller with following components:
• #10 conductive washer FIG 5-C
• #10 lock conductive washer FIG 5-D
• 10-32 conductive nut FIG 5-E
Note: Torque nut ( FIG 5-E) to 20-25 in/lbs.
Levelers to Controller
Controller must be connected to levelers through a wire harness
using 8 or 10 AWG wire.
•
Use 8 AWG wire for leveler rated above 10,000 lbs
or wire runs longer than 30 feet.
•
Use 10 AWG wire for levelers rated at or below 10,000 lbs
or wire runs shorter than 30 feet.
Leveler End ( FIG 6)
A. Use the following Delphi ® or comparable components to terminate
both leads coming from the controller to lower motor connector
of the 7.5K or 10K levelers.
• 12065863 Connector Male FIG 6-A
• 12052172 Terminal Male FIG 6-B
• 12034170 Cable Seal FIG 6-C
• 12059897 Secondary Lock FIG 6-D
1. Strip wires ( FIG 6-F) back about 3/8˝ ( FIG 6-E).
2. Slide cable seal ( FIG 6-C) onto wire with neck of cable seal facing
stripped metal in wire.
3. Push cable seal forward to align neck of cable seal with edge of
insulation of stripped back wire end.
4. Put stripped wire into crimp wings closest to mating end of termi-
nal ( FIG 6-B) and neck of cable seal (around insulation) into sec-
ond set of wings furthest from mating end.
5. Crimp metal from wire to first set of wings.
6. Crimp cable seal neck (around insulation) to second set of wings.
Then snap secondary lock ( FIG 6-D) onto connector ( FIG 6-A).
7. Minimum of strength of core crimp without insulation crimp
should withstand a pull of 300 N (75 lbs).
8. Crimp dimensions:
CORE : 2.4mm (.094˝) high 5.05mm (.20˝) wide
INSULATION : 7.6mm (.30˝) high 7.4mm (.30˝) wide
NOTE : Insert the terminals into the connectors with the flat bottoms
of the terminals oriented toward the connector locks.
B. To terminate 8 gage wire leads from the controller to 15K levelers
use the following components:

3. Pin connectors to match pins in Auto Position Control Board as
shown in FIG 3.
4. Insert Molex ® connector from wire harness into control board.
5. To address communication with the air suspension system, the con-
troller must have a single signal lead provided for “Air Dump”
(
FIG 3-O) and a single signal lead provided for “Air Fill” ( FIG 3-P).
PRE-DELIVERY PREPARATION

OPERATION
BEFORE OPERATING THE LEVELERS
ƽ
CAUTION
PERSONAL INJURY
• Stand clear of the vehicle.
Before operating the levelers, you must do the following:
1. Park the vehicle on a level site. Check for rocks, holes, or other
obstructions. Warn all persons to stand clear of vehicle.
2. For a motorhome,
• Put the vehicle transmission in PARK .
• Engage the vehicle PARKING BRAKE .
• Have the vehicle engine running.
3. Do not extend the slideouts until coach is level.
ƽ
WARNING
VEHICLE CAN TIP
• Levelers must be on firm solid ground or surface prior to operation.
Soft/spongy ground may allow levelers to sink.
• Area below and around leveler must be clear of obstructions.
• Do not place blocks under the leveler for additional ground clearance.
LEVELERS ARE SHIPPED IN THE ERROR MODE STATE.
To take controls out of error mode state, complete a successful
ALL RETRACT (as defined in items 1-3) under TO RETRACT.
4. Put stripped yellow (+) wire end into contact pin ( FIG 15-52) and
crimp together. Crimp must withstand a minimum pull of 75 lbs.
5. Put stripped red (-) wire end into contact socket ( FIG 15-R2) and
crimp together. Crimp must withstand a minimum pull of 75 lbs.
6. Insert the contact pin ( FIG 15-S2) into the female housing ( FIG 15-S)
until it is secured. Then slip seal into housing.
7. Insert the contact socket ( FIG 15-R2) into the male housing ( FIG 15-
R) until it is secured. Then slip seal into housing.
