Glance at the tach and ignition warning light as it dies, but before you
push the clutch in, knock it out of gear or switch off i.e. the momentum of
the car is still spinning the engine. If the tach is still registering revs
then the ignition LT side is OK, but it could be HT or fuel. If the tach
has dropped to zero even though the engine is still spinning then the
ignition LT has failed, which could be due to the ignition itself or the
ignition relay. If the fuel and temp gauges start dropping as well then it
is probably the ignition relay or its connections. If the warning light is
on whilst the engine is spinning, but out when it has stopped, even though
the ignition switch is still on, then the 12v supply through the ignition
switch has failed, either the brown to it no longer has 12v, or the white
between the switch and the relay, or possibly the switch itself. And all
that without getting out of the seat or even coming to a halt.
