battery is draining

ok for sum reason on my truck lately my battery has been draining over night,but wen i disconnected all the wires from the battery which didnt come stocki was left with 2 wires,i didnt disconnect them over night but it strated up right away,i waited bout 20min.i kno prob one of my switchs in the truck has sumthin to do to it but this never used to happened. n all the problems started when i started having probs with my comps.so now i got botch comps on diff switchs but i dont kno if that has sumthin to do with it.

if your compressors are wired directly to the battery you could possibly have a leak which in turn will make you pressure switch kick the compressors on....a night time of compressors running off and on in the cold will drain a battery pretty quick.

i dont have a pressure switch yet,so im not sure wats happening.
