Odd coincident electrical failure?

[RChriste]

Recently the turbo on my 04.5 failed and I've had the truck sitting in my driveway while I soaked everything down with penetrating oil for about a month with the idea of not breaking anything during replacement. At the time of my turbo failure I had no other known issues. Rebuilt turbo swap went well, but now I have no instruments, interior cab lights, signal lights, or hazard warning lights. There may be other symptoms I haven't discovered yet. While the truck was sitting I tried remotely unlocking the door one day and had no success so had to use key. The hood had been ajar and the underhood light was on that whole time, also no dash lights or instruments when key was turned to on, so came to the conclusion that my batteries were dead. Threw 10 amp diagnostic charger on driver side battery and it also indicated batteries dead. Charged batteries, charger after several hours indicated charged, and now as described, I'm missing several key electrical functions. I have looked at and even removed fuse 8, which appears good. Did I do something to kill my instrument cluster or did I have a coincident failure of the cluster with the turbo? I installed a turbo wastegate solenoid that came with the rebuilt instead of my old one, if that may be a factor? Haven't tried the original yet as I discovered this problem late last night. Btw, truck starts and runs great.

Thanks to anyone who replies!

I would buy new Batterie, pretty sure they are Dead even when your little charger said they are charged.
A battery that is suckled out to below Zero for a month - it would be a miracle to get them back alive.

Thanks for the input Ozymandias. I'm thinking the batteries are ok because they have been holding enough charge to crank the engine normally for the six days since I charged them. Started the truck this afternoon. Keep the ideas coming!

Check the fuses and look for any ground wires that may have been removed or disturbed during turbo repair. bg

Thanks for the suggestions B.G., any particular fuses besides Fuse 8?
