Do any of you have a location diagram for all of the ground wires on a '96 f-series? I'm looking all over the service manual and can't seem to find out where they are all located.

I found this for a 92 Bronco a while back, it may not cover all the grounds for an f-series but it's probably a good start.

A list;
battery to frame to block
battery to RF fender near battery
firewall to block (at upper intake support bolt)
w/h (wiring harness) to left side of rad support
w/h to LF fender at hood hinge
w/h to cab behind both kick panels
w/h to frame at LR corner of rear frame crossmember (trailer towing)
clip-on cab to RH radius arm bracket
clip-on front (engine) skid plate to rad saddle
The body (mounting plate) of the fender mounted relay solenoid must be grounded to the fender - it's bolted on, providing a ground.
I think that's all of them. Feel free to add to the list.
If you don't have a good ground on a circuit, it doesn't matter how much power is in your battery - if the circuit can't complete, you have nothing. Or very little, which is more confusing.
