Well that put the kybosh on the idea it was dodgy system voltage.
I'm sorry I have no more ideas on what it might be.
Here's a thought. Corrosion/condensation/contamination on the #1 fuse holder..?
Pull the fuse out and give both it and the holder a good clean might be an idea. At least then you've eliminated another possibility.
You know, it is an open cab and that top fuse box had water and corrosion all in it. I noticed after I bought it of course. I cleaned it up and replaced bad fuses. But I didn’t spend a lot of time on it. What’s the best way to clean that out good? That was 6 months ago.
Oh, cool. Thanks! It won’t pull up the crimp tool on the cat site but I googled and it shows $1700!! That can be crimped with a regular crimper right?
