2008 GMC went dead after turning ignition off

[Terry Grissom]

I turn my truck off after getting home last night and my truck went dead. No power no interior lights no juice to the charger,  nothing,  and I charge my battery and still the same problem. Completely dead although the cigarette lighter still seem to work weird

I was having a similar issue on my 2009 Silverado 1500 about 5 months ago. There's numerous folks who have had the same or similar problem and it turned out to be corroded battery cables. My truck would drive fine, andthen once I'd turn the key off it acted as if the battery had been totally removed.

Both my positive and negative cables had deteriorated, especially the negative. Also, part of my issue was I found the nut holding down the positive cable to the starter solenoid was loose. Both cables totaled about $120 combined and around an hour to replace.

Hopefully this is your issue!

Battery cables, ignition module, main fuses. . .

You'll need a meter to chase wires to diagnose.
