Last year I purchased a 1987 Dodge B150. I believe I have an overcharging issue, but need some help figuring out what may be causing it. Recently I installed a new Autocraft Platinum AGM battery, new 60 amp alternator, and new voltage regulator. At rest I have 13.33 volts when measuring across battery terminals. At idle with it hangs out between 14.8 and 14.89. Turn the lights on and it's around 14.4 -14.6. When revved with lights on or off it runs up to 14.9-15. My manual says the voltage should be between 14 and 15 if the charging system is properly functioning. Everything seems a little higher than what I'm used to seeing. Thoughts?
