I just installed a new battery (1994 Silverado 4x4,5.7).
Right after I start the truck the needle on the voltage gage goes a little
over 14,after 5 minutes it goes back to 14.
It did this since I had it almost 8 years.
I had a 700CCA and 800 CCA's.
I noticed yesterday riding,I had the lights,wipers,defroster on high and
radio on.I just installed the new\battery.I noticed the amp Gauge after
putting all the above electrical items on the voltage gauge dropped to about
12,13 amps.It stayed like this for about 5 minutes then went to 14 amps and
I stopped and put it in park,revved the engine to about 2000 rpms.I did not
see the lights go brighter nor any change in other electrical components
that were on.
My alternator tested good. Is this normal.Could it have anything to do with
the bigger battery???I doubt it,just curious and not to informed on this
