What it is
The Johnson & Starley ignition lead is a spark lead used on the manufacturer's Hispec and Jb25PB warm air units and Janus water heaters. It carries the high-voltage spark from the ignition source to the burner electrode so the appliance can light. It is listed under part number 1000-0705400.
Signs this part needs replacing
- The appliance fails to light or locks out with no spark at the burner
- Ignition is intermittent, with the burner lighting on some attempts only
- The lead insulation is cracked, brittle or shows heat damage
- Arcing or tracking marks are visible at the electrode or ignition end of the lead
- The spark jumps to earth rather than at the electrode
Before you order
- Confirm the appliance model and GC number against the fitment list above
- Check the connectors and routing on the failed lead match the new lead before fitting
- Inspect the electrode and ignition source at the same time, as a fault there can mimic a failed lead
