LEVELING AND STABILIZATION

Purpose

This document outlines the process of replacing an existing Level Best control with a new replacement.
NOTE: This document has been modified from the original Kwikee 1422271 Rev. 7 APRO3 release.

Safety

Before starting any work read these instructions. Disconnect the chassis battery before beginning any work
on Level Best System.

Procedure

Removing Old Control

NOTE: Disconnect the positive cable from the battery before beginning any work.

Cut the wires going to the Level Best Control approximately 1 to 2 inches from the sensor (Fig. 1A).
Remove the wires attached to the two small posts on the motor control solenoid. Leave the battery
cables in place (Fig. 1B).

Remove all the spade connectors from the valve solenoids (Fig. 1C).

Unscrew the hose clamps connecting the jack motor control unit to the motor. Pull the control unit
and all the wires away from the pump unit (Fig 1D).

Cut the yellow wires that go to each jack from the control unit (Fig. 1E).

The control is wired to the pump using one of these two styles of connectors.

LEVELING AND STABILIZATION

Installing the New Control

1. Check the condition of the pump motor solenoid by measuring the resistance of the primary coil. To
do this place an ohm meter across the two small posts of the solenoid with no other wires connected.
If the ohms of the solenoid is lower than 4.3 or higher than 14 ohms, the unit must be replaced before
installing the new control.

Install the daisy chain harness. This harness is identified by its red color, nine spade connectors and

one ring terminal. For Steps 2-6 Refer to Figure 2.

A. Attach the ring terminal to the bolt on the motor side of the solenoid. Then attach the spade
connectors to the inside spade on the valve solenoids working your way around the manifold
from 1T through 4T (Fig. 2A).

B. Attach the next spade connector to the 4-way valve solenoid and pass the remaining section of the
daisy chain across to the 4B valve solenoid. Attach the spade connector to 4B through 1B (Fig. 2B).

Attach the wiring harness pigtail to the pump by attaching the wires corresponding to the valve

markings on the top of the manifold (Fig. 2C). Wire TD1 will not be connected at this time. Wire TD2 is

not used at all for this installation so it can be coiled, tie wrapped and secured at this time.

A. Connect the black wire with the ring lug to the ground bolt on the side of the pump (Fig. 2D).

NOTE: On some pumps this ground lug will be on the back of the motor and have the black battery cable
connected to it (Fig. 2E)

B. Connect the red wire with the ring lug to the pump solenoid on the battery cable side of the
solenoid (Fig. 2F).

C. Connect the white wire labeled SOL + to one of the empty small posts on the pump
solenoid (Fig. 2G).

Connect the 12" jumper wire included in the kit between the remaining small posts on the solenoid

and the ground bolt on the side of the pump (Fig. 2H).

Install the 16' multi-wire harness (Fig. 2I). Route the end with the two connectors that mate to the

control panel through the firewall and into the dash area near the control panel location (Fig. 2J).

At the small connector of the multi wire harness that goes to the control panel, are yellow, blue and

black wires. The black wire is not used. Connect the yellow wire to an ignition source that has 12 volts

when the engine is running.

A. Connect the blue wire to the park brake wire. This connection must show ground when the park
brake is set. Identify the park brake signal wire in the chassis harness. The park brake switch and
signal wire will usually be found on, or near, the park brake pedal assembly. This wire will show
ground or 12-volts positive when the park brake is applied, the type of signal will vary from one
type chassis to another.
