My solenoid is connected with red from the starter button to the rt side (pwr), and ground off the starter button to the center.
The left of course is the side to the starter.
That gives me another one to look at, thanx.
What is meant by intermittent? It says it cuts out for 20min....
Any high amp solenoid will have a duty cycle but most don't give that data because they are vehicle specific. It doesn't actually cut out, it means (as a guideline) that if you are going to put 750 amps through it for ten seconds you should let it cool for that time. 750 amps is roughly double what the average 12 volt starter draws. Most manufacturers recommend that you don't crank an engine for more that 20 seconds anyway.

Yours is the original solenoid? If so, it's wired like this.
#1 goes to the starter motor.
#2 goes to the starter button.

Well I've updated the 12v that someone before me had already converted. I rewired the whole truck, but the cluster, etc. is wired the same as in the manual.
What is weird is that I thought this year ('48) had a single terminal starter button, but mine has two terminals (one for connection to power the other to the center post on the starter solenoid). So the right side of the solenoid is connected to the power source (bat +), the center to the black wire off the starter button, and the right side to the starter itself.
Then someone has updated your solenoid and replaced it with a grounded case type. Your circuit will then look like this. Where #3 is feed from the battery, #1 goes to the starter, and #2 is the power feed from your push button switch.
ok, I thought my solenoid was bad but after replacing it, the new one just clicks also?
It has the proper voltage (as measured). My starter button is a two wire, so I have red going to #3, and black going to #2. Same configuration was when I got her.
What are the "red" and "black" wires? We can't see your truck.
Take a #16 piece of wire, and go from the battery to the small terminal on your solenoid. Does it crank?
This is how the later style (51-on) solenoids with the two-terminal starter button get wired. This assumes your new solenoid is the later style, is that what you bought?
I edited the schematic to show for 12v/(-) ground, which I see you have. You don't have to run power to the starter button thru the ignition switch, you can come directly off battery power (that was stock). But then accidentally bumping the button (or a kid pushing it) will crank the engine, likely with it in gear...

The power off the battery 12V+ goes to right side of solenoid, and that goes to the starter button. The starter button returns to the small terminal (middle), The left side of the solenoid goes directly to the starter. This was how the truck has been for 2 years.
Typically if I wanted to start the truck while under the hood I'd run a wire from solenoid battery side, and another wire from the small middle terminal. As long as the ignition was in the on position, I could touch the two wires together and start the truck. Saving using the starter button
Mine is a 1948 running the cluster and ignition switch per the manual. So your diagram wouldn't be my configuration. But it's the same premise.

Yea, you can crank it over without a key in the ignition no starting of course, or if running cranking it while already started and possibly moving. I found that strange but understood that was the default configuration.
