If the shunt in the amp meter is thinning from age or corrosion, it will pass more current to the needle, and make both charging, and draw current read high. A amp meter that has run pegged for a while will possibly be heated from over current to the point that the shunt night thin. At any rate, Using a different gauge might determine the truth.
Bat voltage under high idle, charged battery, no lights on, should be 14.2 to 14.5 volts. If so it is OK. Congratulations on the A, and your expectation of birth. JimN
