what exactly do i do???

A 0.02 amp draw would theoretically take 3000 hours, or 125 days, or 17.9 weeks to empty a 60 amp hour battery. That's not your problem. A fully charged, 100% healthy battery will show 12.97 volts unloaded.

DON'T DO what dwaite72lnghrn suggested! Never, under any circumstance pull either of the battery cables when your truck is running! And never use a multimeter to directly measure ANY amp draws that may exceed 10 amps, like the alternator or battery ground, battery positive side! If you want to measure greater than 10 amps draw with a multimeter, get an inductive clamp for the multimeter. I'm not kidding, do things the right way the first time.

If you pull a battery cable when the engine is running, you effectively remove the "ballast" of the alternator, which means instead of getting a smooth direct current at around 13.5 to 14.5 volts to the electrical system, you get a 3-phase regulated current that can range from 0 to 30 volts. Your alarm, ignition, the alt's voltage regulator and infact any and all equipment that use transistors or integrated circuits could be damaged permanently.
