Battery voltage

[qship96]

I measured 14.34 volts at battery terminals right after a cold start and then 13.7 volts after a 5+ mile drive with engine at idle speed.....will somebody perform the same exact routine and post their voltages? wondering if these are within spec.

12.25v prior to startup
14.22v 30 seconds after startup, only accessory running was the radio
13.85v 7 miles and 15 minutes later

Thanks Goody....guess the ole alternator is still alive and well at 286K.

14.80v immediately after a cold start and 13.87 at idle after 6 miles and 15 minutes.

Dewd, you need to drive that puppy a little more often!

12.25 is down there pretty far...
