I replaced my battery because I kenew the old one to be wearing out. It was completely dead one day so I bought a new one. I went on one cruise the day after installing the new one, appx 3 weeks ago, and today the new battery is completely dead. What is a logical trouble shoot on this type issue? No switches were left on, that was the first thing I checked. Car is a 69 Dart GTS 340 not any elec mods other than ignition and an electric choke.

either not charging correctly or a short? did you have the alt checked? (take it to Autozone for a free check) if you suspect you have a short? remove neg cable, hook a volt meter between the cable end a the batt terminal. MAKE SURE key off doors closed all lights off...car should be just about elect dead
If you show volt draw, start pulling fuses one by one

With your VOM on "volts" check the charging voltage at a fast idle at the battery and at the alt & as R70runner said take off either batt cable & set your VOM on "amps" & hook it inline between the cable end and the batt post. With everything off should be no draw, then switch to milli amps & should be no draw. Start on the amps scale then move to milliamps if the amps scale shows zero.

Does your car have a clock? The old mechanical wind clocks drew enough to kill a battery after a three weeks of inactivity. Craig

I am thinking there is a draw somewhere. It was a brand new battery and I started the car maybe 4 times with it in two days, then it sat in the garage for about 3 weeks before I went to start it again.There are NO aftermarket electrical items installed on this car other than electronic ignition and an electric choke on the carb. I'm thinking it may be a switch sticking somewhere like a brake light or interior trunk light maybe since I didn't notice the brake lights on and I walk around the back of the car to lock the garage. I will try the meter/check fuse method first and see what happens.......once I take the battery and get it fully charged again.
