Can you unplug the free axle solenoid? Bottom right of first pic. Just above and to right of coil. Which fuse is blowing 3/15 or 4/15?
I can "unplug the free axle solenoid?". Fuse 3/15A is the fuse that keeps on blowing.

Can you find another page that tells us where or what the combination switch is? Do not need to unplug the free wheel solenoid. Unplug the water temp gauge and the oil pressure light. Should be the one plug with 4 wires on it.

I made a mistake it was position 4/ 15A.     I think this wiring diagram is not correct. It has the wrong color for one of the wires going to the ignition coil. Also there is no resistor immediately next to the ignition coil.

Things in the diagram are not placed where they are located physically. Since 4/15 is the one blowing, disconnect the solenoid we mentioned earlier and the plug on the meter and oil light and see if that makes the fuse quit blowing.

Everything connected to line 5 is also suspect. Fuel pump, carburetor and the free wheel relay at top of one of the pictures.

[SOLVE SOLUTION]
For anyone following this thread here are the updates. I removed the battery's metal housing to get access to a 30A and 60A fuse. They both were fine. The 60A fuse had signs of overheating. I did a continuity check on both and got zero resistance. I reseated them and put the battery back together.
The wiring diagram I have is not correct. The colors of the wires going to the ignition coil are Yellow and ( Black and White ). This diagram states they are Yellow and ( Black and Red ). This is not correct. The diagram also states that there is a resistor connected to the incorrectly labeled ( Black and Red ) wire. Following the harness if facing the truck and passenger side on the left going to the right, driver side the first things I see are a chassis ground wire that grounds near the ignition coil, second I see a connector going a wire deeper into the engine and third a wire to the distributor. Either way I would like to be wrong and to discovering where. But I see no resistor.
I decided to clean the two chassis ground points in the back by unscrewing them and scrubbing the area with a brass wire brush. I did the same to the chassis ground point by the battery. After this I placed a new 15A fuse in position 3 and placed the ignition in run the voltage was stable and no longer dropping out. The blowing fuses ended.
Then the Subaru Sambar Carburetor Solenoid , SKU: 16196-KA140 at the top on the passenger side of the carburetor caught on fire. It burnt the black ground wire off. I took some of the engine a part to trace that wire. I found that the carburetor solenoid was plugged into the harness with a yellow wire and black wire was ground where the carburetor solenoid attaches to the carburator. I disconnected and tested the engine and now I have spark.
I think if we had the correct giagram things would have been much simpler.
Thanks everyone.
