If I may add a little kaka to the kettle, I went out and inspected my TR3 to
see how I had it hooked up. I discovered that the poles on my (Lucas) coil
are not labeled + and -, they are labeled BAT and DIST. Wot now, guvner?

> Now, what I recall from my Navy electronics days (uhm, more than 3 decades
ago), electrons flow from positive to negative, holes flow from negative to
positive, and it is the difference in potential between the two that makes
one
"negative" as opposed to "positive." In other words, a positive 20 volts
will
run to a positive 15 volts because the difference in potential is still a
negative 5.
Electrons flow from negative pole to the positive pole. Holes, or lack of
electrons, flow from the positive pole to the negative pole.
The coil will work when connected either way, but the spark plugs will work
very slightly better when the wire from the ignition switch is connected to
the positive-marked coil connection on a negative earth car, and to the
negative-marked connection on a positive earth car.
