There are 12 volt coils, and there are 12 volt coils.
Coils normally marked as 12 volt are made to have a resistor in front of them. Other 12 volt coils have the resistor built into the coil.
Rambler was one of the few that used a coil that had the resistor built in.

glad you got it up and running. Thanks! Not sure if you've been keeping up with the old thread I started a couple of months ago about the overcharging issue but after installing the new coil the voltage has dropped down to normal levels and it's not overcharging anymore!!!! I'm talking between 13.2 - 14.2 volts from idle to acceleration!!!! Could it be the coil or a connection on the coil was the issue and the reason it was overcharging??? I don't think it's a coincidence but maybe it is...

I don't think it's a coincidence but maybe it is... have you Ohmed out the coil? possible internal short pulling the Voltage down You could always reinstall to see if the issue recurs But sometimes at the end of a long journey it's best to leave things alone

"had one go out like that while driving and it vaporized 2 inches of copper and about 5 inches of insulation under the dash. showed something crazy like 100 volts output." and i'll just kinda' guess all the "magic smoke" escaped, causing a great deal of consternation.............. the smoke pouring out from under the dash at 55 with all the windows down was quite impressive, I will say. I don't think I have ever pulled over that fast before and jumped out of a car. the fact it still was running and everything seemed to be working was amazing. I was near some small town in podunk and a garage was on main street and they offered to take a look, since the car wasn't on fire. lol.

No good. These are for positive earth systems. Perfectly fine if you turn the container upside down before injecting the smoke. Doing so reverses the electrons polarity ๐คซ๐คฃ
