Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to Resistance 
Remove spark and earth leads from electrode and spark generator
Measurement:
Test 1:
Measure the resistance across the ignition lead. There are two types of ignition lead.
If a red ignition cap lead is fitted expect short circuit / zero resistance across the lead.
If black ignition cap lead is fitted expect approximately 1 KOhm across the lead.
Test 2:
Measure the resistance across the earth lead.
Resistance should be short circuit / zero resistance.
Inspect the leads for good overall condition and that
they fit securely to the electrode and spark generator.
