Finally found the cause of my overheating

If the fans are turning at 1/4 speed because of lack of current availability, engine temp would/could be affected.
Fans? It's a 64 Dart with a slant 6. Unless it's a a/c car it has a belt driven 4 blade fan. And as a side note, unless it's puking coolant out all over it's not overheating, regardless of what the gauge says.
