MSD Coil blew, absence of ballast resistor cause?


Recommended Posts

BAM. And while driving my girlfriend and I to get gelati. No embarassment, she's used to me spending almost as much time under the hood as driving the thing. Anyway, I had the old Hitachi coil in the back because I knew this might happen someday.

 

Anyway, the coil wire end on the coil side was actually BURNT. Was the absence of an extra ballast resistor the cause? I asked the question if I needed one a while ago but didnt get a straight answer. I'm going to try out an Accel Superstock now (no way am I going run the slothy stock coil, reliable as it may be) so do I need the resistor, and which kind would I need.

I'm sorry....when you say ballast resistor I'm curious as to which part you are talking about.:-\ I've never seen a resistor on a coil before....but I have seen capacitors (aka condensors). Are we talking about the silver can with a mounting tab that has a wire coming out of it (possibly out of each end)? One wire goes to the coil and if there, the other wire usually goes to the block.

Just curious.

I have a Gregories book

 

I says that the 79 - 84 models had ballast resistor.

 

I have read that the resistor is used to privide a voltage drop for a lower impedence coil so that when cranking, when the voltage is less, the voltage drop is less, and the coil recieves a voltage closer to 12v when starting

 

But dont quote me on that:drunk:
