Battery voltage/current issue (?)
More than once on these forums the issue of tight tolerances on battery voltages has been mentioned.... Believe me, I have searched.
Yesterday, I replaced the alternator on my '02 1500 w/ a 5.9.
The alternator failed at the parts store and now the truck will start with a prolonged jump but will not idle on it's own, it needs a stick between the seat and gas pedal.
All I have is a voltmeter so here's what it looks like.
Running @ 1500 RPM 13.9- 14.4 volts
Off 12.4
*** Went out and bought a new battery. While there, tested the old one. CA was only at 74%.
New battery
Running @ 1000 RPM 13.85 steady
Off 12.5
New battery works fine - lasts long time ( I hope)
