m. report
fresh charge on battery 40 amp for 30 minutes on saturday trickle charger s=
ince 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 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 al=
ternator... 0.0001 volts
I also took battery back to Wal mart and Quintella checked it...=C2=A0 batt=
ery is good based on her years ofbattery experience
