Re: voltage question
14.8 is a tad high, but not dangerously out of range. Your voltage regulator could be faulty. You don't have to pull apart the entire alternator to change it. It comes out the back of the case with a couple of screws. Still, if it is going bad, the rest of the alternator probably isn't far behind. Auto part stores sell rebuild kits which include new regulator, rectifier, brushes, bearings, etc. for $50 or less. They are not hard to do. Mine took less than an hour with no special tools. Beats a couple hundred for a new/rebuilt alternator.
