Anyone have any suggestions on methods for tracking a battery drain? All of a sudden the battery is dead after two or three days. The battery is new, less than a few hours of run time and few starts. Nothing has really been hooked up lately. The is on my Bus that's not on the road yet.
Take the Ground (Negative) strap off. Look for any little sparks as you do; that'll be a tipoff. Then, connect a small 12V pilot lamp (speedo bulb maybe) in series with the Negative cable (one side of bulb to chassis, other side to the battery Neg post. Does it light?
You can also use a multimeter in place of the bulb. Set it on the highest Amp/milliamp scale to start.
If you get a bright light or more than 50 milliamps, pull fuses till it goes away.
If you get a high reading and pulling fuses doesn't stop it, the alternator could be at fault; try disconnecting it.
Lots of ways to skin the cat, but that's one route to start at.
