Doing some preventative maintenance on my cm870

[Evotrucker]

Hello people! Happy memorial weekend.

So today I was looking over the truck and started to do some preventative maintenance on the truck, trying to catch or find anything out of the ordinary. So I started of with cleaning the valve cover n then saw the cables on the starter had some nasty oxidation on it n cleaned them of and when I was putting the buy back in for the red cable I snapped the sob of by over torqueing it :/.

So what are my options for that? I wanna get back to work tomorrow but I wanna fix this properly today.

Also noticed those two cables was or is supposed to miss one those small middle things or prongs? Someone tell me what you call those things lol. If it’s missing it’s inside one of those connectors n I think that connector hooks up to the thermostat housing? So that could be where my issue is with the over heating or inaccurate signs.
