DURING ALL TESTS
START:
Read all warnings above before continuing.
If the vehicle runs normal in one direction but does not run in the opposite direction then go to
the
Solenoids sequence.
If none of the three solenoids pick up (click) when the accelerator pedal is depressed then go
to the Forward & Reverse Switch sequence.
After any repairs are made, completely retest the vehicle before
lowering the drive wheels to the ground. Failure to retest the vehicle
could result in unexpected movement of the vehicle resulting in severe
bodily injury and/or property damage.
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 severe bodily injury and/or property
damage.
Rotating rear drive wheels are a potential hazard. Keep hands,
arms, legs and loose clothing away from the rear drive wheels while
conducting tests. Failure to do so may cause serious bodily injury.
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.
