Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to DC Volts 
CH Demand
Gain access to PCB (use Insulation Mat as required)
Ensure the meter is set to full range mode.
Ensure the meter is set to full range mode.
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Measurement:
Reset any lockout conditions and allow the ignition sequence to commence.
Measure voltage across Pin-4 (Brown) and Pin-1 (Blue) of connector X2 (top right corner of PCB).
At rest there should be approx. 30Vdc at the connections which should rise to approx. 60Vdc while sparking.
NOTE:
Sparking should commence at the same time as the fan starts and will last approx. 5seconds then stop for 5seconds, this will repeat 5 times.
