well, that's three days or so I'll never see again... started over on =
the=20
diagnosis... A fellow ford guy in Canada mentioned something about the=
=20
alternator exciter wire being used when alternator was larger than 80 =
amps. I=20
didn't use one... I called EZ-wire tech guy and we discussed it. He as=
sured me that with a one wire unit the exciter wire wasn't=20
used (it gets itself excited ) As we talked he asked what my battery v=
oltage=20
was when the alternator was above 1500 rpm and I told him in the 13 vo=

Then he asked what my alternator voltage was and it was 14.6 or so... =
He said=20
just to check it and bypass all the wiring to run a wire straight from=
the=20
alternator to the battery +... I asked him if it cured the problem sho=

just leave it in place... he said sure , that way you are getting char=

voltage straight from alternator
So I built a #4 cable and installed it from alternator to battery +...=
guess=20
what ??? 14.6 at alternator and 14.6 at the battery... All this high t=

diagnosis... was just an exercise... At least I know that all my conne=

and terminals and electrical stuff is good and well grounded and bless=

I'm gonna call him back tomorrow and get him to explain EX-wires reaso=

John, here=E2=80=99s a little electrical theory for you, hope it helps=
=2E=20
Resistance measurements on a vehicle are not generally useful for circ=
uits that handle higher currents but works better for circuits that de=
al with signals. 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 ground point for all measurements) or volt=
age drop across a wire is the best way to find bad connections or unde=
rsized wires, your readings will not be near the end of the range or t=
he meter. That=E2=80=99s why I recommended the series of voltage readi=
ngs all along the wire from the alternator to the battery.=20
This approach also works well for grounds. When working with grounds i=
t is best to use a single ground reference point or do voltage drops a=
cross each ground wire.=20

Check charging voltage @ alternator post, alternator terminal, termina=

enough to find the problem.=20

Monday a.m. report
fresh charge on battery 40 amp for 30 minutes on saturday trickle char=

hooked up H.F. 500 amp load tester, voltage reading same as VOM at 13.=

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 =

stopped test at 15 seconds and two minutes later battery was back up t=

next step will be check alternator output at battery and terminal poin=

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'=20
of 1/0 cable....that=20
don't sound right
need to measure resistance of cable I guess...
as an aside... checked voltaged between frame ground and the case of t=

I also took battery back to Wal mart and Quintella checked it... batt=
