If you suspect you have a drain on your battery you can determine amp draw test. Remove Neg. Battery cable and place an amp meter in series or between cable and battery post. The amp meter should be ste at highest setting on meter and then reduce setting until reading is noted. Meter should be placed with red lead at cable and black lead at battery post to be correct polarity.
If reading is found then remove clock/radio fuse if equiped first. Then remove each fuse 1 at time to determine if a fused circut is at fault. You can use a test light if not a big draw and just an indicator but a meter is only 20 bucks for a cheapo version. Some circuts are not fused like starter in many cases so have fun.
