I have checked out the battery as OK. Put 10Amp current meter on both
positive lines from battery & get 4 amps for a few seconds & then
almost zero or no current! Putting both positive lines together (one is
Starter & other is many controls) & measuring current did show some
current drain for a short period late last night. One unusual think is,
some of the times I connect the lines to the battery in a test, the
Tahoe doors go into a locking phase.
Could a door locking relay be sticking?
Anyone else been through this mysterious symptoms?
Battery alone over night & is OK. Battery connected over night is NG!
Dome lights are cut off.
Battery positive connection disks have been cleaned of corrosion.
