3.1 One Bar - Low Battery Voltage
Section 3
Understanding VSI Controller Diagnostics Codes
This code could indicate discharged batteries, failed batteries, or poor battery connections. Begin by recharging the batteries
and then refer to Section 1 to check batteries and connections.
3.2 Two Bars - Left Motor Disconnected
The left hand motor has a bad connection. Check the connections to the left hand motor.
Test Left Motor Open
Check that the batteries are fully charged and in good
condition; and check all cables and connections. Check
the connections to the left motor, look for a loose or damaged
connector. Remove the 9-pin Beau plug and check
the resistance across pin 3 and pin 4 as shown in (figure
A3.2.1). If the meter reads between 0 to 1.5 ohms, then
replace the controller.

If the meter reads between 0 to 1.5 ohms, then replace the controller.
Otherwise, check both brushes on the left motor. (Refer to
Section 4 Step 9 of this Service Manual for easiest access).
Ensure that the brushes are not excessively worn, (replace
as required). Top access for Motor brush shown in (figure
A3.2.2)(requires shroud removal).
A3.2.2
Use the meter to check the resistance across the two bottom
contacts (thicker wires) on the 4-pin motor connector
as shown in (figure A3.2.3). If the meter reads between 0
to 1.5 ohms, then replace the main harness. If none of the
above corrects the problem, replace the left motor.
