Lynx I MkIII purchase

[Mike Cecil]

Alistair,

This might sound crazy, but have you felt the temp of the coil when it stops running? The symptoms you describe are exactly what was happening when I first drove my first F15 in the 1980s, and we soon discovered that the 4.5 volt coil was getting 6 Volts - and gradually overheating. After 20 minutes, it had cooled, and the engine started again without a problem, then would run until the coil overheated. No/little spark, so no ignition.

Of course, your Lynx system is 12 Volt - is the coil also 12 V or a standard 4.5 V Ford coil working via a resistor?
