Charging issue?

[elorenzof]

Good morning,

I have a 70 C10 which i rebuilt from the ground up. I have dakota digital gauges, and Sniper 2 with the Hyperspark ignition. I've only about 30 miles on the engine, it's a 383 stroker. New everything. CVF serpentine belt system with the 1 wire alternator. The alternator is grounded to a clean spot on the frame, and I'm running 6 gauge wire from the alternator to a 200amp fuse, then to the battery. Which is a new battery.

When i start the truck it puts out (the alternator) 14.3v according to the sniper handheld, and to the dakota digital gauge. after the truck "warms up" i guess you could say, maybe even after a mile or so, the sniper shows the volts at 12.8 during idle sitting, (the dakota digital gauge confirms w the same reading) but when i accelerate it goes to 13.8 to 14.3 voltage.

I thought i had a bad alternator so i called CVF racing and they sent another one out. Installed it yesterday, same result.

what am i missing? I was wondering if anyone else has come across this issue and how they solved it, or is it really even an issue?
