1933 Dodge 5-window coupe

This 1933 Dodge is a solid rust free car. Never any rust, ll original, ever modified. The car has not ran in about 8 years. I put fresh gas and changed the oil, lugs and changed the points. It started up fine and ran great. The problem is it has the charging system charged backwards. I can't remember how to fix it. I had the wheels sandblasted, ut I have not finished the sidemount wheels. The car is very nice looking. Someone borrowed the hood ornament and never returned it.
