Yep, it went clickity.
But seriously,
I'm going to do two things.
1. Clean all the grounds as I've had a lot of steering fluid (atf) sprayed on everything, plus diesel and motor oil. All those leaks and issues have oiled everything. I carry brake cleaner for that sort of thing.
2. Carry a spare solenoid and what I need to install it. 11mm, 13mm, 14mm, 15mm, 16mm, sockets. I only need three of them, 11mm does the signal wire. 13mm to unhook the ground cable, and one for the starter bolts and positive cable nut, but I already forgot the size. I carry all that already. I took my front driveshaft out and put it aside until I'm done towing. That helps a ton. The trucks up high enough that even my gut fits under it, so those 9-16 tires are good for that too, not so much after 14 hours for carpal tunnel , still numb.
Using WD-40 to clean the grease off my hands, and brake cleaner to get the WD-40 off, works slick on the roadside. As an added plus, the brake cleaner points out all the spots needing triple abx and a band-aid.
