Charging Issue

I havea 00 Silverado Z71 witha 4.8 and Auto Trans. Here lately if the truck sits for more than a day with out being cranked the battery is dead. Put a new battery in last July. When i put a meter on it the Alt. shows 14 volts out put. once it is cranked it will start everytime with no problem. Any Thoughts?:banghead:

there is no one answer. you have to place a amp meter in line with the battery ground connection ,,,,the current should be less than 1/4 amp then remove fuses one at a time to find whats sucking the power down..

any after market add ons are the first to be disconnected because these are the first step in fixing this


you have a drain problem not a charge problem.
