need some fan info please

Sorry it is on my 67 valiant with the slant 6. i tend to forget that not everyone know what i have. lol. when i got her she had a large aftermarket radiator with the lower outlet on the wrong side. and an electric fan assembly as well. but i have been running into an issue of the battery trying to go dead while i am driving with the radio on. so i am going back to the factory radiator and fan.

I have to think there is some other problem with your charging system since I run an electric fan, CD player, headlights, heater, wipers and various other electrical devices and don't have any charging or low battery problems at all.
I guess we'll find out though from the sounds of it.

Does your fan run all the time or just when it needs it?
