Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to AC Volts 
CH Demand
Gain access to PCB (use insulation mat as required)
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Measurement:
Reset appliance as necessary.
Measure the voltage between connections 1 (brown)
and 2 (blue) on connector X2B on the PCB.
At 15 second intervals mains voltage should be measured
for 3 seconds as power is sent to the spark generator, this
will be repeated 5 times until lockout occurs.
Is the voltage measured as expected?
Notes:
1. Timings quoted are approximate.
2. Reset appliance and repeat test as necessary until outcome is determined.
