Overcharging Issue & Car Start Issue

The amp meter really cannot tell you if it is over charging or not. All it really does is indicate current flowing to or from the battery. Negative needle indicates current drawn from the battey. + needle indicates current flow to the battery ie altenator charging. When my Dart 1st starts up the amp meter pegs over to the + side for a few seconds as the altenator puts back what the starter just took out.
