Yesterday, I started working on it with the goal to see if it would turn over. I started by changing the oil, replacing all the spark plugs, plug wires and battery cables along with putting a new battery in it. There was not a battery in it before and I suspect the old one is in a tractor somewhere. As with most farmers, Grandpa had a habit of swapping things whenever he needed it. For example, the plug wires were a collection of different ones from a variety of vehicles.
Anyway, got everything done and I have no power when I turn the key and no lights from what I could tell (interior cab light is busted).
I'm attaching photos of the battery, starter and fuse box. I really need to find a Chiltons for this truck and I think I'll order one now.
Any ideas on what may be the issue? I think, at the very least, I need to clean up the fuse box, but beyond that, I'm out of ideas.
