4. Check voltage output from the circuit board.
a. Remove brushroll and belt.
b. Disconnect motor terminal at circuit board.
c. Connect voltage meter – set on AC Volts – as shown.
d. Voltage should read 120VAC. When the switch is in the low and high speed settings the
headlight LED will flash. If voltage exists move to step 5. If no voltage exists, replace PCB.
5. Check for voltage at motor leads. Voltage should read 120VAC. If no voltage exists, replace
motor wire. If voltage exists, replace motor assembly.
