charging system blues

Check again. The black wire at BATT post on alternator should be hot at all times, switch on or off.
batt new a week ago - batt good. checked wires at back of alt - none hot without key on. key on - black wire hot & the field with the two blue wires gets hot. single green on other field not hot. double blue wire at ballast hot with key on. bulkhead plug looks good outside & in - hot under the hood & inside things work. cranks & starts , lights... good ground at vr, checks were done w/a test light. went back with a meter & had batt volts at each check. i'm thinking "damn amp meters"
Hey MichaelSiple,
Electrical problems suck..going through some myself!! I would pay attention to the simple stuff first including 67 Dart273's suggestion to load test the battery. Just because its new doesn't mean anything. A battery can show 12 volts on a meter and still be bad. This will show up on a load test. Bring it back to the place you purchased it as most reputable auto supply stores can do this for you free of charge.
