NO SPARK

my bike randomly cut out when i was riding yesterday. i had no spark. i was bummed out cuz i was 25 miles from home with my girlfriend on the back of my bike.
today i changed the plugs. the old plugs didnt look bad at all.
i checked the coil. it read 4.3. i checked the capacitor with the volt meter and got 0.00.
i checked my buddies capacitor and i got 0.00 also.
im running a hughs handbuilt PMA, pamco, and sparx capacitor. its a 83 with stock carbs. just rebuilt. i havent heard any problems since i converted it to the PMA.
this is my only way around town.
any ideas?

My '83 did the same thing. What was the problem?

My standard recommendation is to temporarily wire the PAMCO directly to a fully charged battery that is not connected to the bike in any way. This to see if it is an ignition problem or a PMA problem.

Found it, broken wire to kill switch. Bike has other electrical issues, but it's running.
