What it is

The Sime 6186537 is an ignition lead measuring 780 mm, used to carry the ignition voltage from the control board to the ignition electrode. It is a service part for boilers in the Sime Planet DEWY range. The lead forms the high-voltage path that produces the spark at the electrode during burner start-up.

Signs this part needs replacing

  • Boiler fails to ignite or locks out with no spark at the electrode
  • Cracking, charring or brittleness visible on the lead insulation
  • Spark tracking or arcing to earth rather than at the electrode tip
  • Intermittent ignition faults that worsen in damp conditions
  • Loose, corroded or damaged terminals at either end of the lead

Before you order

  • Confirm the boiler model against the fitment list above
  • Check the existing lead length and terminal type against the 780 mm lead
  • Inspect the ignition electrode and its gap, as ignition faults can originate there rather than at the lead
