CAUTION

INSTALLATION CHECKOUT

Before operating the vehicle, carefully complete the following checkout proce-

dure. If you ﬁnd a problem during the checkout, refer to the diagnostics and

troubleshooting section (Section 7) for further information.

The installation checkout can be conducted with or without the handheld

programmer. The checkout procedure is easier with a programmer. Otherwise,

observe the LED for diagnostic codes. (The codes are listed in Section 7.)

Put the vehicle up on blocks to get the drive wheels off

the ground before beginning these tests.

Do not stand, or allow anyone else to stand, directly in

front of or behind the vehicle during the checkout.

Make sure the keyswitch is off, the throttle is in neutral,

and the forward/reverse switches are open.

Wear safety glasses and use well-insulated tools.

1. If a programmer is available, connect it to the programmer connector.

2. Turn the keyswitch on. If your system includes a momentary power

enable switch, you must press this switch also. The programmer should

power up with an initial display, and the controller’s Status LED should

light up and remain steadily lit. If neither happens, check for continuity

in the keyswitch circuit and controller ground.

3. If you are using a programmer, put it into the diagnostic mode by

pressing the DIAGNOSTICS key. The display should indicate “No Faults

Found.”

If there is a problem, the LED will ﬂash a diagnostic code and the

programmer will display a diagnostic message. If you are conducting

the checkout without a programmer, look up the LED diagnostic code

in Section 7 (Diagnostics and Troubleshooting).

When the problem has been corrected, it may be necessary to cycle

the keyswitch in order to clear the fault code.

4. Select a direction and operate the throttle. The motor should begin to

turn in the selected direction. If it does not, verify the wiring to the
