Have a hunt mag set up on a unit construction triumph, had spark on the first few kicks and then it disappeared. Replaced the coil and had a guy set it all up right, was throwing a nice big spark. Put it back on and the same thing happened. Wired to kill switch and then ground. Any body ever seen this before, or have any suggestions as to what it might be? Any help would be great?

1st. disconnect the kill wire and see what happens.

there was a batch of mags from Hunt a while back ( with a date code in 2009-2010) that had the rotor magnets incorrectly timed to the coil, this usually blew the condenser first then the coil, a temporary fix was to add a another condenser to the kill wire terminal.
The only real fix is to send it back to Hunt.

How are you checking the spark?The circuit will only be complete if you use both leads.
If you leave one plug in the head with the lead connected,you should be able to get a spark from the other lead if you fit a plug to it and ground that plug against the head.
If you fit plugs to both leads and touch the plug bodies together (both plugs not screwed into the head),both plugs should spark at the same time.
