From another Kansan, welcome to the forum!
I'm originally from Ark City, although I live near Tulsa now. But, we used to live in Wichita, back when I worked for Boeing and then KG&E. Plus my wife lived in Newton for a while, and I worked for the AT&SF railroad there as well as well as in the north yards in Wichita when I was going to college.
We have a member's map (Bullnose Forum/Member's Map in the menu) and I'd be happy to put you on there.
As for your truck's issues, you should open a new thread in the main section about that. I say that because the main section gets more attention and, therefore, more help.
Having said that, my guess is that your positive or negative battery cable has a bad connection. Or, that the cable itself is bad. Do you have a voltmeter? If so you should try the voltage drop test (Electrical/
Voltage Drop Test). That will point out where the problem(s) are.
