ok guys, i have a msd 6al and 8580 billit dist. with bronze gear for my car, it will only have spark as long as its out of the engine. i pulled it, pluged it in and spun the shaft. plenty of spark.. drop it in the motor and crank it. no spark. pull it out and spin it. good spark. took it to a friends shop. dropped it in a old dist. machine, wired it up, good spark again. took it home dropped it back in my motor ,, guess what no spark again.. i am at a loss here. and this thing is driving me nuts.. any ideas?
