Step 7.
If all switches appear to be good:
1. Check the brown wire on the wing rocker switch as follows. Place one lead of the multi-meter on the brown wire from the
micro switch. Place the other lead on the white/green wire at the PCB connector (#6) you should read 120 volts with main
power switch “ON” and floor/carpet switch in carpet position and Tool activation dial/rotational valve handle in the tools “OFF”
position.
2. If the voltage is low, go to the rotational valve micro switch and disconnect the brown wire from the handle connector and
the black micro switch wire turn the main power switch “ON” and place the carpet/floor switch to carpet. Place one lead from
the multi-meter to the brown wire from the handle and the ground wire to the number 5 or 6 PCB connector, voltage should
read around 120 volts.
3. If the voltage is within normal limits, the micro switch is faulty.
4. If voltage is low then the problem is in the handle connector or the handle wiring.

Step 8.
1. Unplug the direct air motor and hook it up directly to 110 volts.
2. If the motor runs
continue to B.2. Step 9
.
3. If the direct air motor does NOT run replace it and reassemble the vacuum and retest.
B.2.
Step 9.
1. Check the wiring to the direct air motor and the PC board.
2. If all the wiring is good (not pinched and all connectors good) replace the PC board and retest.
3. If any wiring or connectors are faulty, replace them and retest.

Step 10.
1. If the motor runs reassemble the vacuum.
2. If the motor does NOT run replace the wiring harness; reassemble and retest.
NOTE: If vacuum still will not run call Tacony Technical Service at 1-00-43-459.
