Finally getting back into my 85 ttype. I am very rusty since I have not tinkered with it for years. I put a new battery on and had my friend check the starter and alternator at napa. The Charging Test showed 15.76 Volts. Is this bad? If the alternator needs replaced what size should I go with. Also, would a volt booster to the fule pump cause this? Thanks for the help!
