a. If you don’t have continuity then back track until you get it then
troubleshoot the components you had to skip until you find the
culprit (Swivel, harness, power lead to power switch, power switch,
power lead to cord winder, cord winder contacts, power cord).
b. If you do have continuity then continue to 2.
3. Check the neutral side between the neutral blade on the power cord plug
and the neutral terminal on the control board. This checks power lead to
the cord winder, cord winder contacts and neutral leg of the power cord.
a. If you don’t have continuity then back track until you get it then
troubleshoot the components you had to skip until you find the
culprit (Power lead to cord winder, cord winder contacts, power
cord).
b. If you still have uninterrupted continuity then see step 1, the AC
Voltage source must be suspect or there are multiple problems
with the unit.

Use a Multimeter in Ohms or a Continuity Tester to:
1. If the problem is intermittent you should consider performing steps 1 & 2
while flexing components (swivel, harness, power to power head, handle
switch assembly, power lead connections up in the handle or down at the
hose end blade to N) to save time.
2. Since the main motor works we only need to with the portion of the circuit,
components and connections that affect the power nozzle.
3. Toggle the power nozzle handle switch to the right. Check between the
hot blade of the power cord plug and the B receptacle on the power nozzle
(Be sure the main power switch is on).
a. If no continuity then the problem should be in the power nozzle
handle switch assembly.
b. If you measure continuity then check the between the neutral blade
on the power cord plug and the neutral or A receptacle of the power
nozzle handle.
