EASY!!! Just bypass the damn thing, if it starts, runs, it is bad!!!
They cost $7.00 People say you can test them. People say you can by pass them for a short period. I suppose you can but I have never been successful at it. I always carry an extra one in my glove box
If it is trying to start but just won't OR if it starts and shuts off as soon as you let go of the key that is what it is most of the time. They are the curse of the Mopar

He hooked up a meter to it and the voltage was really low coming out of it.
Start bypasses the one for the coil anyway - assuming it hasn't been cutup

Just doing what I do
The starting circuit by-passes the resistor and switches over to power through it when you let off the key. When they begin to fail, resistance goes up and the spark from the coil gets weaker until they eventually are done. Testing them is unreliable since they can show good when cold and get worse as they heat up. Easiest thing to do is to keep a couple of spares and swap one out if you are having any ignition issue...like Tike says.
Could be the connections too.
When the ignition switch is in "run" the ballast resistor will drop the voltage going to the coil. More when its hot, less when its cool.
When the ignition switch is in "start" the power goes directly to the coil side of the ballast resistor. Coil should be getting system voltage - which of course is battery. Somehting like 11.5 to 12.5 depending on how much starter is drawing it down.

That would explain why it was harder to start when hot. And it was getting progressively worse. The nice thing like you say is they are small and cheap and probably faster to just install and so easy anyone can do it.

I will get a spare for the glove box since the new one is Made In China

Also, for all you electronic ignition folks, the chrome box can fail too. I keep a spare and swap it out just like the ballast resistor. The one my car came with was making the ignition break up and stall just off idle and a simple swap fixed it.

Yep, you just don’t want to leave it that way for too long or it will fry the points and shorten the life of the coil. Fine for testing though.

Hey bartender!
I love you too George! But let's try and keep this thing on the down low!
Benricky is buying the "old" 17X7 wheels!!!
Keith...are you listening? I am an old fart and have had many MANY mopars and have replaced many of them. The first place I look
Keith are you reading this....A grumpy old man I am.

I've tried 3 coils, 2 dizzys including one rebuilt by hoppy. Wired exactly to this chart for points
But IF you by pass it. Do not run it long or you could have more problems they are there for a reason
..
Jeezz I drove a hot wired 383 for over a hundred miles, lost the keys. Got new key, started it and never had a problem. Replaced the points as part of a regular tune up later...
IMO Not that big a deal....For testing!! OK! If car runs then the resistor is suspect!

Maybe someone of us will spend less time than I did today if they just change the ballast resistor. Now I know. Thanks, Tike.
IF you ran a wire from the batter to the coil and bypassed the resister but didn't remove the resistor I can believe that. Hell I believe everything you say .But try removing the resistor and using the hot wire I am just saying it will burn things up .I don't know why everyone just refuses to accept the fact that the resistor on a mopar has a function
David is about the third person just lately .So why should I even say anything no one listens
I'm all ears
