battery is r un down each morning. Not sure if alternator is fine or not. Battery takes charge from charger just fine. dashboard battery meter indicates about 13v or 14 v while driving with no dimming of lights while raising or lowering windows all 4 at once.
Can tell you that there is a constant drain of 30ma dc with all fuses removed! What's happening here?

Hi Gary-- Here's some info about checking for drains,hope it helps:

Answer: Here is the procedure we use to isolate a battery drain. Remove negative battery cable from the battery. Using a 12-volt test light, hook one end to the negative battery post the other end to the negative battery cable you just disconnected. The test light will glow or “light” if there is a drain. If the “light or glow” is faint, that is probably normal draw for the clock or computer. If the “light or glow” is bright, then there is a large drain. That should be corrected. Now start removing and replacing the fuses one by one until the light goes out; that one will be the circuit with the drain.
