How to check for a drain on battery?
Well I searched for a while came close but didn't get the answer I was looking for. How do you check for a drain on your battery? Do you disconnect the positive battery cable and hook my digital meter in between the cable and battery.My meter has three settings for amps: one fused circuit for checking uA(A AC) the other for mA(A DC). I also have an unfused circuit for 20A Max. Is this how you hook it up and what setting do I use?

Use the 20 amp setting and hook it up between the negative terminal and the main negative cable with all negative wires disconnected fom the battery. the rule of thumb is more than half an amp is unaccepable. If the draw will light a test light its too much

I just wanted to say thanks for the help. I tested it just like you said and was drawing .2 amps on the meter,and it would also light the test light. I had my relay for the fog ligths wired wrong,it was always giving power to it. It didn't make sense because they always worked right and have been hooked up like this for over a year. I just had to switch the wires and it's perfect now. Thanks again!!
