Hello, Just bought a f350 6.0 v8 diesel duel was running great after bad storm last night I went out to start truck this am and when I put the key in and turned it to wait for glow plug all lights began to flash on the dash and in the cab. I turned the key off and the gauge needles still vibrated for few sec. I have never seen this before any help please it is only transportation

all connections i can find are tight Batteries are 6 yrs old and have charges of 11.47 and 8.58 think should replace them and hope that corrects problem.
any thoughts at all please let me know

 

It looks like you have a dead cell, so replace both batteries before you can really start troubleshooting.

Here's the 6.0L no start guide:
