hey guys so when i first got my new engine in the GT 3 months ago the first time i got it to fire up my MSD ignition coil crapped out, bought a new MSD coil and it worked, been running for 3-4 months now, Then yesterday the car died in the middle of the road, got it to my shop and my co worker found that the coil was not putting out a spark but was getting power and has a good ground. So that makes 2 coils in a 3 month period. whats the deal here?? Anyone else have this issue or know the cause??
If you do a search on MSD coils I think you will find a spotty record when it comes to quality control. Those that like them swear by them, but a lot of folks stick with a stock system. The other issue may be too much resistance in your spark plug wires.

I put a new coil on today and it fired up and ran but then it died again, new coil is dead. Found that the above object in the picture was 1 loose at its bolt position on the block and 2 the wires where melting a little. What is this thing in the pic? is this causing the coil to die every time?? how can I tell if its bad?? and if it is bad where can I get a new one??
I can get another coil, ive done some research and found that if the ballast resistor is bad the coil will run hotter, but maybe my coils are just burning up. if thats the tach filter, below that you can see that there is another object that the wires run through that might be the ballast resistor. I really dont want to burn up another coil.
the next black section those wires run into is the ballast resistor. so im gonna test the resistor tomorrow with an ohm meter and make sure its good, then make sure i secure the tach filter to the block like it should be and then put a new coil on it. If the ballast resistor tests bad I will replace it.
Ok so it is a tach filter. I don't have a ballast resistor. My next question is , can a bad tach filter cause the ign coil to burn up like it has 3 times now. Really need to find the cause of the coils burning up. I did replace my radio I have double checked all the wires and everything is good. So its something else, I check all the fuses and none are bad. The only Hong I can see is the tach filter wasn't grounded to the block and the wires are melting. Is this the cause??? Thanks
