My 2003 GMC Sierra SLE is a battery drain. Battery checks OK, but
keeps discharging. I attached amp meter and began pulling fused
looking for a reduction in the drain. Found that drain was reduced
when IPC/DCI fuse or the radio fuse was pulled.
Just sitting, there is a 1.4 amp drain on the battery. Pulling the
IPC/DCI fuse lowered drain to .9 amp then pulling the radio fuse
lowered it to .2 amps.
Anyone have suggestions on what causing the drain?
