Quick question

[71DodgeDemon340]

Should my ballast resistor be getting too hot to touch?

 

[greymouser7]

Sounds like a LOT of current. Becareful, my buddy burned down his car when a high current wire of insufficient gauge shorted out.

 

[71DodgeDemon340]

I mean its not smoking but ive heard its normal to be real hot

your ballast resistor definitely gets hot that's why its in a big ceramic block its taking 13 volts down to half that ..

 

[71DodgeDemon340]

Ok but is there any way to tell if its getting to hot? I mean you cant touch it for more than a second

Is this while it's running? Or just with the key on? It should be a lot cooler with the engine running.

 

[71DodgeDemon340]

No its hotter than hell while its running. Should i replace it with a new one

You can't touch them. Did you get battery voltage back down where it belongs? Hope to 'ell you are not RUNNING it at 16--18V !!!

If you have a high output aftermarket coil, they will run even hotter.

It's probably Ok. Just keep a spare in your glove box.

Hey 67 no lol installed the mopar performance ( not the blue one) regulator tonight and shes back to in spec no more 18+ volts lmao its got a mopar performance coil on it but i dont think its high output.

the ballast resistor is a restrictor ( log jam say )of electricity whatever your alternator is putting out goes to it and then it reduces it down to almost half going out will melt fingerprint if you touch it..they are hot n I mean HOT when running
