sorry for slow response... helping daughter and sil move...priorities!=
!!
Monday a.m. report
fresh charge on battery 40 amp for 30 minutes on saturday trickle char=
ger since=20
then .. battery voltage 13.4 this a.m. checked with two different mete=
rs
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 and=20
voltage read 10.8 (still in the green scale)
stopped test at 15 seconds and two minutes later battery was back up t=
o 12.7
next step will be check alternator output at battery and terminal poin=
t
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 t=
he=20
alternator... 0.0001 volts
I also took battery back to Wal mart and Quintella checked it... batt=
ery is=20
good based on her years of
battery experience

When it died, did any of the electrical items still work? Lights, etc=

it first occurred ,, when I tried to restart, .. starter just clicked =
and I=20
remember the a/c fan still blowing
Donald... How large is the cable from the alternator to the battery? =
feed=20
from battery to alternator is #4 wire
Dave... I was thinking a dirty battery clamp. battery clamps are ne=

year and clean, no corrosion on connections
John... How is the volt meter in your truck grounded, to the frame o=
r to the=20
motor? voltmeter in dash is grounded to dash frame voltmeter used =
to check=20
under hood is grounded to frame not engine. =20
I'll go back and check ground connections. Alternator has a ground ter=
minal of it's=20
own...=20
it's #10 wire grounded to the frame and of course the alternator is gr=
ounded through it's=20
mount.
Pat... what is the relationship between the frame terminal & the rest=
of the=20
electrical system? Terminal on the frame rail is fed by a=20
4' piece of #4 wire from the i/p solenoid lug where the cable from th=
e battery is connected to the solenoid.
Jimmie.. What's=20
the voltage at the terminal with those accessories 'on' but the engine=
'off' =20
hmmm ?? don't remember checking that, =E2=80=A6 I'll do that
How big is the alternator? 100 amp single wire from CVF racing
ya'll have given me lots to check and recheck and some I haven't thoug=

going back through my diagnostics and check connections too. I bough=
t a 500=20

Battery=20
is under the cab and I have to lower it to check it out and with the l=

I have to raise truck on jackstands.. silly me, I thought battery woul=

low maintenance item ...duh. so checking at a shop somewhere is a ve=

points I'm considering.... larger ground wires from frame to engine...=
