Cofi Ignition cable BV1 09CA036109

The Cofi Ignition cable BV1 09CA036109 is a replacement part for the high-voltage connection between the ignition transformer and the ignition electrode in a burner. It is silicone-insulated to withstand the voltage produced by the transformer and the heat near the combustion head. The cable transfers the secondary voltage that generates the spark at the electrode gap. It is compatible with Master 4110.971 models BV100, BV160, BV280, BV110, BV170, BV290, B230, and B360 up to 2010.

Parts of this type are selected by length, connector pattern at both ends, and cable gauge. Before ordering, verify the cable's end fittings and overall length against the original. Inspect existing connector boots and terminal contacts for corrosion or looseness. The cable must match the original in connector type to ensure a secure, dry connection.

A hardened or cracked insulation can allow the spark to track to earth, mimicking a faulty transformer. This may result in weak or no spark at the electrode gap. Check the insulation for damage and the terminal contacts for corrosion or looseness.
