Re: Hei coil keeps going south

Yes had same issue back when I ran a hei, actually melted the cap when the msd took out the second coil, went with the low resistance bushing from msd

But for peace of mind I went with a remote coil with the hei adapter and a blaster ss coil.

But like you I had problems with burnt contact posts but on the rotor instead of the cap had to change twice a year or more foten if not the best quality no matter what brand.

So went with a msd #8361 distributor same cap and rotor for over ten years and both box and coil still runs strong.

Picture of rotor new vs old, mallory pre 2007 was best after that they changed and eorn faster short after I went msd distributor.
