Guy at work suggested a full set of new straps.
Run the big one from block to frame.
Run a 1/2 inch strap from battery to body ( fender )
Replace the old strap from head to firewall.

Alternator possibly too, or is that jumping ahead of the horse?.
A single "strap"? Is that one of those braided wire deals? Those aren't one of my favorites.

Run the first cable from the ground right to the block, I like to go right to the alternator mount if I can. Then from the back of the block to the cab and also the frame. And make sure you clean all connections. Use sandpaper if needed, it has to be clean, you can apply spray paint after to help protect the connection.

Then you can begin testing the alternator / battery, but good connections are critical.

ps, you're friends at work think like I do! LOL..
