VV,
doing great man. Just took my dad who is 91 and bought a 56 Bel Air this past Saturday!

Yea the system is going to make up the drain if everything is working as it should. My 6.0 LS alternator is putting a strong 14.5 out at the volt gauge in the dash even when I have the lights on and AC with fans it never drops below 13 volts.
davepl,
I sorta have what you are wanting to do.

In my dash cluster I swapped over to a volt gauge.

I also have the scan gauge 2 hooked up to the PCM with a volt reading. They are always the same reading as far as I can tell. The dash is a needle and the Scan gauge is digital. They basically read the same.
The dash is tied to the unfused spot in the fuse block so it to me gives me a system reading where the scan gauge reads off the alternator through the PCM.
