Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Disconnect the electrode leads from the spark electrodes and the spark generator on the PCB
Measurement:
Measure the resistance of each of the electrode leads.
Expect approximately 1 Kohm.
Also visually inspect each lead for good general condition, damaged insulation and the condition of the spark generator and electrode connectors.
Is the resistance as expected and the leads in good condition?
