Ignition coil

When I was coming home from driving my car today, it started to miss and almost shut off. When i got home, I shut it off and tried to turn it back on and it wouldn't fire up but it cranked over normally. I grabbed the ignition coil to see if it was hot and it felt like it was as hot as the motor. After driving for 30 mins, how hot are they sopposed to be and is it bad if they heat up?

thanks
 
Not normal to be so hot......I would not only check the coil, but the wiring coming to and from the coil if it is shorting out causing it to get hot....(this is how fires start)
 
If it is shorting out, wouldn't the coil not work at all? or work for a second and then stop?

Well you said it was in and out....Maybe an intermitent (sp) sort??? also you said it wouldnt start after you got home.....That would explain if the coil isnt working at all.
 
I checked all the wires and they are fine. But is it still sopposed to work even when its hot? or no?
 
Its an accel chrome canister style coil and its a 68' 289 motor. Points style ignition but the points have been replace by a pertronix unit.
 
Anyone have any ideas? Its going to be warm and sunny all next week and the problem only happens on those types of days.
 
The coil reads 2.4 ohms with one lead at each post and 11,000 from the center to one of the posts. A new coil reads exactly the same. I get 11.XX volts at the positive side of the accel coil while running. Im running a ballist resistor that reads 2.8 ohms. At the parts store their strongest resistor was at 2.8 ohms also so i really cant reduce the voltage anymore i think. Not much more i could think of that i can do. any ideas??
