Voltage Issue

I have an 85 c10. It has the TBI engine switched out for a carbed SB. I have moved the battery to the bed and the power cable straight to the starter. It has a 3 wire alternator that I had tested at two different places to make sure it is good. The problem I am having is when the truck is running my volt meter is pegged out past 18 volts. I bought a second volt meter to make sure mine wasn't bad, and it also pegs out past 18 volts. What would cause my volts to be so high??? Is it a possible starter issue, a wiring issue? Any help would be great.
