This test is very much recommended when there is a suspicion of Transaxle-Power-Unit parts
faults , or when irregular noises are coming from the Power-Unit . Also when there are
complains about too short travel distance, or battery faults.
For these Tests Connect a DC current meter on the Battery Red Positive (+) Power wire. It is
recommended to use an induction current meter (So that no physical connection is needed) .
Make sure the meter wires are far away from any moving parts. The meter Range needed is up
to 40 Amperes .

that they are free to turn without touching the floor . Squeeze the speed lever to maximum and
run the breeze for 1-2 minutes before measuring . Than measure the current consumption
should be between 2.5A to 3A .
For Drive test load
drive the SL-3 at full speed on level surface with a user weight of 70-80 Kg
