Depends on the ambient temperature, not to mention that all
alternators have a voltage versus amperage specification.

Stupid me, here I've been using an AVR and a trans-conductance
tester all these years.

If you have 12.1 VDC on the battery at rest, then the battery is fully
charged. If you have 14.1 VDC on battery with engine running then the
alternator is good. Put the volt meter on the battery at rest and have
someone crank the engiine over while you read the voltage, it should
not drop belwo about 11.0 VDC if the battery is holding a good charge.

At 12.1 volts, the battery is less than 50% charged (close to
25% charged).

What is the alternator output. Wth engine running, put a volt meter on
the battery and check the voltage, you need to see 14.1 VDC and not
less that 13.5 VDC if the alternator is good. Likewise the battery,
with engine off, same test and 12.1 should be the reading.

I have a 96 voyager and times it would start fine and with no problem
at all, then other times it would not start all. This is what happens:
come home park the van, wake next morning turn the key and nothing,
just the clicking sound. get a boost and it starts right up and runs
fine.............. shut it off later and it starts right back just fine
and continue like that for days. Then out of the blue I would park it
[say at the mall] come back and nothing; click click click.........
dead battery! What could be draining the power from my battery like
that?
I check to be sure nothing was left on and everything was off. Please
someone help me. It dont cut-off, just wont start after parking.
