hey --

Some background ...
440+6 Challenger, stock restored 38 amp alternator. New NOS regulator
All new wiring throughout car. No ground issues - I ran one from the bellhousing to the firewall.

I ran a 10 gauge wire from the back of alternator to starter relay - to help take some current away from the bulkhead and ammeter gauge

When running car during the day - rpm above 1000 the neddle is dead center.
When running after cranking - needle swings to far right and gradually to center.
If rpm drops below 1000, then needle swings to left - soon as rpm goes up, it moves to right then to center.

Question:
Is it normal for the gauge needle to sit just a hair to the left of center at nightime (lights on etc)?

I checked the voltage at the alternator durring the day - 14.20 it was 14.1 at the battery. Turned on the lights and it dropped to
13.7 -> 13.8.
At night even with the slight needle offset to left - head lights and dash light don't dim.

Expertise appreciated ....

Thanks in advance..

Bill

My 69 Charger does the same thing with factory stock wiring. Pretty much the same numbers too.

thanks for the info -
I am feeling much better now about it...

my Superbee does the same thing with new harness,alt.and voltage reg. You should be OK.....
