jeff=E2=80=A6.     regular led acid battery ??     Everstart Maxx27 80=
0 CCA  regular=20
Walmart battery

When it died, did any of the electrical items still work?  Lights, etc=
=2E?  when=20
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=
w this=20
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=
ht of... =20
 going back through my diagnostics and check connections too.  I bough=
t a 500=20
amp load tester yesterday and will put sufficient load on the battery.=
  Battery=20
is under the cab and I have to lower it to check it out and with the l=
ow truck,=20
I have to raise truck on jackstands.. silly me, I thought battery woul=
d be a=20
low maintenance item ...duh.   so checking at a shop somewhere is a ve=
ry large=20
pain.

points I'm considering.... larger ground wires from frame to engine...=
=2E alternator to frame and check resistance from solenoid lug to the =
terminal on the frame...   the saga continues

thanks for all the replies and points to check...   you guys are the b=
est
