Yes; the ballast resistor gets HOT
as I found out the hard way, 35+ years ago or so.

Leave the stock ballast alone, it should work fine for years.

My Dad bought a New car in November 1964,
it was a 1965 Valiant 2 door sedan.
I have been around a few Mopars since then. ;)

I do suggest get a spare stock style resistor for a spare,
because they do fail once in a while, I have one in my glove box,
I also carry a spare tire {besides the spare tire under my shirt HAHA}.



Okay, I tossed the stock one from the points system back in and it runs just fine. However; is the resistor supposed to get hot to the touch? As I understand the ballast resistor its purpose is to limit the voltage to the coil after ignition. I'm not sure how hot is too hot but I'm sure at some point something will fail if the ohms are out of whack.

Anyone know what the voltage should be running into the coil while the car is running? MSD apparently has a .8 ohm ballast designed to work with the blaser coil, I probably can't go wrong with that - and it appears to come with a bracket that should work on our firewall.

Can anyone say if this is a realiable option?
