My 2004 Chevy TB started having charging battery, ABS and airbag lights stay on after starting the truck and remain on for long periods of time before going off & restoring the air/oil/gas/water gauges to operational status. I had the 125 mega fuse replaced & have checked all other fuses in the fuse box. What next??? This all occured after tring to jump start my wife's car last week.
Problems afte a jump is not good.
Try a neg. cable battery disconnect first.
Then I would get it on a engine/body capable scanner and check for codes first thing.
If any codes post back codes.
