I'm posting this for a friend with a 71 Bee with a 383. He tells me within a couple minutes after starting the car the coil gets hot enough to burn you and won't restart if shut off. The car has electronic ignition and he has changed ignition boxes (MP orange) and ballast resistors ( Napa 2 terminal replacements- likely wrong). He has bought a new MSD coil for it but has not tried it yet and is getting all kinds of advise but the most common being poor grounds. Any ideas?- electronics problems are not my bag....
