I had a similarly aged Lucas Sport Coil fail on me last winter; Car would
run fine for intervals of decreasing length, interrupted by poor running and
eventual quitting. After sitting for a short while, car would run fine, but
for a slightly shorter period than previous.
Kind of along the same lines I just discovered a bad coil wire (6 mo old
Bosch) that had been causing my car to run poorly at idle and occaisonally
die. I had thought the problem was carburetor related but when turning the
car over after it quit one evening I spied with my eye a spark jumping from
the coil wire to the firewall. Never would have thought it! Switched out
the coil wire and car immediately ran beautifully! Also, in replacing the
coil wire, I seem to have fixed the goofy fluctuation that my temp and fuel
guages were exhibiting. Does this make sense? I know that the tach and
guages are on the same fuse, and with the tach connected to the coil..... ?
hmmmm

and another totally unrelated thing; what could cause a motorcycle to
destroy spark plugs? Front plug on Vtwin looks fine but won't fire after a
few hours, Spark to the plug is strong continuously but something has
caused 2 plugs to fail w/in 2 weeks under light riding. Coincidence?
