Question about 2003 Triumph Speedmaster
With Ignition switch off :-
1st Check for bad connections, broken/crushed wires, continuity & resistance between the cap, HT lead, coil, ignition coil primary wires
2nd Disconnect the CDI unit from its connector & check for the same between the loom side of the connector back to the coil
3rd Check coil is earthed
If all OK suspect the CDI unit but double check everything first( there are some more checks as well), as these are very expensive
Please rate this solution well if it has helped !!
Any comments welcome
