Triumph Repair: Ignition Problems, rotor arm, coil wire

Question
Hi Howard - need help. I have a fully restored comlpetely stock TR3A (with a new wiring harness).  It runs great, but has suddenly stoped.  I have replaced, points, condensor, coil, rotor arm and plugs.  But still have no spark.  Test lamp checks show that i have cuurent at the coil and the points are "switching" the coil "on and off" when they open/close.  I have visually inspected all HT leads, distributor cap, checked all connections, gaps and grounds but still no joy.

Appreciate any assistance you can provide.

Answer
Hi Lee,
Pull the coil wire out of the cap and hold it about an eight of an inch form the head and with the ignition on, open and close the points several times. If the coil wire does not spark the coil wire is bad or the coil or the condenser is bad. If you do get a spark, remove the distributor cap and hold the coil wire about an eight of an inch from the center of the rotor and open and close the points several times. If you can jump a spark to the center of the rotor, it is bad. If not then look closely at the inside of the cap to see if there are any carbon tracks anywhere. If so the cap is bad. If you have the coil wire and plug wires in real wire no need to test them, but if they are the newer carbon wires, you need to test them with and ohm meter. I think is was supposed to be 5k ohms per foot of wire so you can have an idea of what is good and what is bad. Only other item is the plugs and the ground strap from the engine to the body.
