Cranks over and starts, once you turn it off no power on the inside
So I would go to start my 1998 Chevy
Silverado 1500 4x4 Z71 and would have no
power on the inside of the truck, would go
and put a jump pack on it and I would have
all my power back on the inside, I would
take off the pack and let it run for 5-10 min
and drove it around to recharge up the
battery, came back home and turned it off,
went to go start it again to see if it would,
same thing again, had no power on the
inside of the truck but I went to autozone
and got them to do a test on the battery,
alternater and starter, all three of them
passed the test, any ideas,
