A. Vacuum has no power.
A.
Step 1.
1. If there are lights in the handle switches there is power to the handle,
continue to Step 2.
2. If there are no lights in the handle switches, there is no power to the vacuum or the power cord is faulty.
a. Check the power source.
b. Replace the power cord if damaged or faulty.
c. Retest the vacuum.
NOTE: Vacuum may not run even though the lights in the handle are “on”. If the handle is plugged in
and
turned “ON”,
the handle switch light will turn on even when the handle isn’t installed in the vacuum.
A.
Step 2.
Handle switches are lit but neither motor will run.
1. Ensure the handle is installed correctly. (See
Figure A. Correct Handle Installation
)
2. Push the reset on the back of the vacuum and retest (See
Figure T. Description of Vacuum
)
3. If the vacuum still does not run
continue to Step 3.
A.
Step 3.
1. Unplug the vacuum.
2. Remove the handle. Check the connector ends for any burnt pins.
3. If the connector ends are in good condition
continue to Step 4.
4. If faulty connectors are found, replace the wiring harness.
5. Reassemble the vacuum and retest.
A.
Step 4.
1. Plug the power cord in and turn the switches on.
2. Plug a test meter or light into the handle connector at the bottom of the handle, (one lead into the square connector on the
upper right (See
Figure I. Handle to Body Harness Connector #4
) and the other into the square connector on the lower left (See
Figure I. Handle to Body Harness Connector #3
).
3. If the handle has power,
continue to Step 5.
4. If the handle does NOT have power:
a) Unplug vacuum and disassemble handle.
b) Check all connections in handle.
c) If all the connections in the handle are good, change the wiring harness or install a new handle.
d) If all the connections in the handle are NOT good, replace any faulty connections.
e) Reassemble and retest vacuum.
