I do appreciate all the input, I put a 250 amp circuit breaker in and the glow plug circuit works perfectly now. I did replace the controller already but I am going to go back to the old controller since I know that was not the point of failure.
I do need to make a secure mount for the controller but with a turbo being installed now my controller is up front right behind my ac compressor.
My theory as to the wire melting was that I had an old 35 amp fast charger hooked up to the main battery while I was cranking a lot. I had to prime the IP and set timing so I assumed the repeated cycling of the plugs killed the 40 yr old wires

The slow-blow feature of links is a commonly-held belief.
"Cheaper" is 100% for sure.
In an earlier post, I asked if modern trucks still use links. It is clear that they do.
To the OP: (1) if both your links blew, I suspect a short-to-ground in the controller, (2) I would troubleshoot the issue and eventually go back to the original two lines going into the controller. Each with either a link or fuse.
If it is the controller, now might be the time to relocate it to a cooler, less vibration, location.

So long as all the wiring and components downstream from the 250 amp breaker are robust enough will probably work. I'm hoping the OP has checked it.

I have checked it, there is 0 resistance on the circuit and the plugs worked perfectly for a cold start. Just one cycle and she fired up. Did a couple starts today and drove her for the first time in a while. My timing might be a little off since she seems to be lacking hp and making a good bit of white smoke. There is also an exhaust leak but these are issues for another time.
For now all is well and this wiring headache is solved. I appreciate the input from everybody.
In my opinion fusible links are a terrible way to protect a circuit. If a certain part is designed to fail it should be easily accessible for diag and replacing. Maybe one day all of those links will be circuit breakers
