battery charge constantly goes down

Hello, does the battery lose charge while operating the vehicle, or between driving the vehicle and starting it again? With anything battery and charging system related, you always have to start by having your battery professionally tested and checked to ensure it is fully charged and able to sustain a load. Once you have a known good battery, then you can proceed checking the charging system - alternator and voltage regulator -- for proper operation. If all is working properly there, then check for any parasitic draw from anything that may still be energized after the vehicle is off. All of this needs to be done step by step, though, to ensure that each part of the system is working as it should, in the proper order. www.repairpal.com/repair-shops
