Pete :
Not to belabor the obvious, but you should get 3 sparks per crank revolution
at the coil wire. If you can still get spark from the coil wire, but not
from the plug wire(s), I would suspect the rotor has failed. Saw this on a
TR4 on the way back from VTR 2001, ultimate cause was a bad plug cap, but
the rotor was shorted between the copper on top and the dizzy shaft.
Didn't try a timing light, but I've had them not fire on a badly fouled
plug, the same thing might happen for a shorted rotor.
Also check that the pickup hasn't been dislocated relative to the slotted
wheel. This was one of my Crane problems.
