Test Equipment Required:
• Digital multimeter (DMM) with diode test function, FLUKE 79 model shown.
• Test harness, Taylor-Dunn #75-089-00
Important Notes and Instructions
• This troubleshooting guide assumes a familiarity with the use of a digital multimeter
including, voltage tests, continuity tests, and diode testing. If you are not familiar with
these types of tests then refer testing to a qualified technician.
• These tests are not intended to locate a problem on an incorrectly wired vehicle.
• Make sure the batteries are in good condition and fully charged before performing any
tests.
• If the vehicle exhibits intermittent problems, it must be in the failed mode for troubleshooting.
If it is running normally when the testing is done then the problem will not be identified.
• Some tests refer to a High/Low switch. The High/Low switch is optional and the vehicle
may not be equipped with this option. If the vehicle is without this option, there is a jumper
bypass installed in place of the switch in the dash.
• All voltage tests are done referenced to battery negative, unless otherwise specified.
•
At the start of each test sequence you will be instructed on how to place the control
switches. While testing, do not change the position of any switches unless instructed to
do so.
DURING ALL TESTS
• After any repairs are made, completely retest vehicle before lowering the drive wheels to
the ground.
Definitions:
• Battery volts = full voltage available at
the batteries at the time of test.
• High: Greater than +4.5 volts
• Low: Less than +1.8 volts
Terminology used:
• The “HOT” side of a switch is the terminal
that the power is connected to.
• The “COLD” side of a switch is the
terminal that the power is switched to.
• FS-1 = Micro-switch in the accelerator
module.
The rear drive wheels may rotate during some of the following tests.
Block the front wheels, raise the rear drive wheels off the ground, and
support the vehicle with jack stands. Failure to do so may cause the
vehicle to move and cause property damage and/or serious bodily injury.
Turn the Key switch OFF then disconnect both of the battery leads during
any maintenance or before disconnecting any electrical component or
wire. Failure to do so may cause severe bodily injury and/or property
damage.
Turn the Key switch OFF BEFORE disconnecting the batteries.
Disconnecting the batteries with the key switch ON may corrupt the
controller programming resulting in a fault code 1 (refer to fault table).
