Since my battery was drawn down (not dead but wouldn't start car) last weekend and after putting on over 2 1/2 hours of driving time, the in-dash voltmeter reads ~14V when key is turned on without engine running. After starting car, voltmeter read ~15V. I suspect this is normal considering the battery won't be fully charged for at least another 4-6 hours of driving time. Is this a correct assumption. After battery is fully charged, what should the voltmeter read with engine running?
thx...
Please note, I did a search and looked at FAQs and only found one post that briefly mentioned that he's seeing 15V with engine running.
