Need help with a Dodge Charger question.

. Heat is resistance
There is the key. If anything is hot it has excess resistance. Could be loose connections, warn out switch contacts, etc.

My 67 dart headlight switch conectors had been loose for so long that they melted the plastic around the connector.

I was able to get another good plastic and tighten up the connectors and clean them properly and re assemble.

On a side note... My ammeter bounces when my turn signals are on. It goes to slight discharge then bounces to charge, swinging to around the first tick momentarily. I think it has to do with how the ammeter works and how the voltage regulator works. Basically a momentary overcharge while the VR recovers from the high current draw when the turn signal lights are on. Like water hammer in the pipes, if you had a pressure gauge on the pipe you would see the pressure drop from static when you open the valve, then slam the valve shut and you would see the pressure rise sharply for a moment then settle back to static pressure ( yes I know voltage is pressure and amps is flow, but the alalogy still holds water pump intended)
