Perry,
Sorry for the late response, maybe you already got your answer.  Anyway, I recently had an education on this matter.  My project is a n/a 3-rotor in a Lancair ES.  I'm using Tracy's EC-2 with six LS1 coils.  They are wired per Tracy's instructions.  There is a fuse for the 3 leading coils and one for the 3 trailing coils.  I started out with a 5 amp fuse in each (couldn't find anything in the instructions addressing this, so I guessed).  BTW, I am not flying, just running the engine on the ground.  Anyway, I promptly blew the 5 amp fuses, so I steadily increased the fuse amperage rating until they no longer blew.  I ended up with 15 amp fuses on each of the 3 leading coils and 3 trailing coils.  I am now thinking about separating them so as to have six separate circuits with one 7.5 amp fuse per coil.  At the very least I will increase the existing fuses to 20 amps for each of the 3 leading/trailing coils.  Hope this helps.

Mark S.

 I'm using LS-1 coils and have my pair of leading coils running off one fuse
and the trailing coils running off another.  What value of fuses are working
for the rest of you?  I blew 5A's on both pairs today.
