Good Morning, I'm hoping someone can point me in the right direction. I go to start my truck @ end of the day, yesterday, as I turn my key the dash lights up like normal for just a split second,twice. Then completely dead. I literally have no power to the truck, no lights, brake lights, etc. I checked 2 fuse sites, left end of dash and left fuse box under hood. It appears all the ignition and power fuses that I've identified aren't blown. Could it be the battery that has been working flawlessly up until the last time it was started? I'll be checking the battery this morning after daylight. Any other suggestions?
Thanks!!!

 

Positive terminal was corroded. Thanks!
