COIL FOR ELECTRONIC IGNITION - '89 ON

Ignition - Ballast Resisted Systems

I'd like a pound coin for every time I've been asked about what these are all about and why they are used. Folk seem to hold them in some kind of awe - but they are very simple. Part No Applications: DLB105, GCL111, GCL143, GCL132 The ballast resisted ignition system was - I believe - developed by Ford when they were experiencing poor starting on a certain prodigiously-used 4-cylinder engine. To get round the issue of the massive current drain caused by the starter motor functioning, the ballast-resisted system was designed. When you hit the starter button/key, a massive drop in available current to the coil occurs as the starter motor does its thing. The colder the weather or the more worn the starter motor, the more current it draws, the less there is passed to the coil to instigate ignition.The ballast-resisted system utilises a 6 (commonly called the 'cold start' system) or 9-volt coil instead of the older style 12-volt item.
