At my alternator the voltmeter reads 13.9 idle and even with the engine
revved. At the battery with the engine revving at abut 3,000 RPM the voltmeter
reads 13.40.

Is it time for an alternator or are those readings acceptable? (I have the 90
amp alt. in there). I read previous post by kim brennan stating batt should
read 13.2 and with bus running the reading should be about 14. Mine isn't quite
14 at the alternator as you see. I guess I'm wondering what are the low
limits and should I replace the alt.

FWIW

The battery after just being charged by sears this afternoon (who sold me the
battery 3 years ago) reads 12.3 when I got it home. What they charged it to I
don't know. But they said it was holding a charge fine so as not to have to
replace it--we'll see.

It was dead this a.m. at about 8 volts and would not crank the engine.

Thanks
