Truck is a 1998 Tahoe with a new 105A alternator (Oreilly Ultima new) and battery cables (Delco). These are my voltage readings taken from the alternator post to battery negative.
Do they look ok? I'm seeing a noticeable drop in a/c blower fan speed when I come to a stop then back to normal when driving. The dash voltage gauge gives a corresponding dip, but the gauge reading never corresponds to the meter readings at the battery or alternator.
Battery voltage: 12.55
14.23V at 2,000 rpm, accessories on
14.36V at 2,000 rpm, accessories off
12.98V at idle, accessories on
14.33V at idle, accessories off
Accessories on is headlights, a/c, radio, rear defrost and blower on high.
Comparable battery readings (positive to negative posts) were nearly the same as the readings from the alternator (maybe 0.1V, if that) so there doesn't seem to be a huge drop between them.
