Always Charging?

[dave`12]

I put a v8 in my 67 c10. Most everything is new; battery, voltage regulator(external), cables, alternator.

I have dual electric fans, an HEI, and an electric fuel pump. Not much else going on. Driving, I notice that the factory battery gauge reads about 1/2 way between the middle and charge. It moves a little while cranking, turning on the lights, and comes down a little at idle, but I mostly stays in this position.

I thought that this gauge should hover very close to the middle. Could this be an issue?
