John, here=E2=80=99s a little electrical theory for you, hope it helps.=20
Resistance measurements on a vehicle are not generally useful for circuits t=
hat handle higher currents but works better for circuits that deal with sign=
als. It is useful just as a open/short diagnosis. Here=E2=80=99s an example.=
A wire carrying 40A current with 1V drop will have a resistance of .025 ohm=
, much too low to be a real indication. Voltage, either to ground (the same g=
round point for all measurements) or voltage drop across a wire is the best w=
ay to find bad connections or undersized wires, your readings will not be ne=
ar the end of the range or the meter. That=E2=80=99s why I recommended the s=
eries of voltage readings all along the wire from the alternator to the batt=
ery.=20
This approach also works well for grounds. When working with grounds it is b=
est to use a single ground reference point or do voltage drops across each g=
round wire.=20

John,
Check charging voltage @ alternator post, alternator terminal, terminal on o=
ther end of 1/0 cable, post that terminal connects to. If you can get to the=
conductor in the 1/0 cable, get that too. That should be enough to find the=
problem.=20

Monday a.m. report
fresh charge on battery 40 amp for 30 minutes on saturday trickle charger si=
nce then .. battery voltage 13.4 this a.m. checked with two different meters=
hooked up H.F. 500 amp load tester, voltage reading same as VOM at 13.4
voltage at frame rail terminal also 13.4
battery has 800 CCA capacity
started test... over 15 second test the battery slowly dropped to 320 amps a=
nd voltage read 10.8 (still in the green scale)
stopped test at 15 seconds and two minutes later battery was back up to 12.7=
next step will be check alternator output at battery and terminal point
ok... started truck... engine at 1200 rpm
meter on alternator o/p- voltage is 14.6
meter on battery voltage is 13.5
hmmm...1.1 volt drop in 4' of 1/0 cable....that don't sound right
need to measure resistance of cable I guess...
as an aside... checked voltaged between frame ground and the case of the alt=
ernator... 0.0001 volts
I also took battery back to Wal mart and Quintella checked it... battery is=
good based on her years of
battery experience
