03 escalade ext having major problem w/ battery losing charge over night. Took to dealer told me to remove aftermarket alarm. Did that! Did not solve problem!!! Something is draining my battery...help please!!!!!!!!

any other aftermart things installed? sound system?

i found the problem! i had a Clifford alarm installed w/ that dei 1700g module. either the idiots that did the install didn't wire the module correct or it is bad. pulle the brain of the Clifford alarm left the 1700g module on battery drained down by the morning. took that module off truck functions as normal.
