Check between frame ground and battery negative. A rusty connection t=

cause all manner of similar problems.

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

from battery to alternator is #4 wire

under hood is grounded to frame not engine. =20
I'll go back and check ground connections. Alternator has a ground ter=

it's #10 wire grounded to the frame and of course the alternator is gr=

Jimmie.. What's=20
the voltage at the terminal with those accessories 'on' but the engine=

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=
