Hey guys, trying to re wire my alternator because one of the wires is dead but there is a rubber boot/clamp that is around the wires and it seems to keep the wires fixed, wires wont slide in or out of the boot/clamp, the boot/clamp has a plate coming out of it that is attached to the alternator case, its like a ground? I'm not sure, but I would like to remove/replace it but it seems the only way to get it off is to cut it off, does anyone have any idea as to what this is?

car is a 77 wagon with 2.8 incase that info is needed, below are some pictures

Yes , it is a standoff , the plate on the wire hold it in place , you can probably find them on most diesel f250 with that alternator,  mine has it also , the reason for the huge alternator is the lower pulley is small and does not turn fast enough to make good output at idle with the lights and A/C running , only the 2.8 pintos and mustang II had them , the 2.3 had the smaller 60 amp alternators but a smaller standoff , pm me your email and I can send you some photos and a wiring diagram, later Blaine

thank you so much for the info, you've replied to my other post too, as far as 2.8s go you've always reached out and I thank you for that, hm, so what is the purpose of it? Is it mandatory? What would happen if I removed it ya think?

The purpose is to keep movement loads off the wiring terminals , being bolted solid to a bolt or stud (an alternator) the engine movement would work harden the copper wire strands , over time they would slowly break away or thin enough burn in half , may take some time for it to happen if you don't use wire clamps , you will also notice the wire in that area is stiffer than the rest , goes for starter wires also ,

ahh so it helps to keep the wires from dying? any guess on how I could remove it and reinstall it? I'd like to keep it I just know know how to remove it safely so I could reinstall it after

thanks so much for the input, after messing with it some more it is removable with out destroying, I thought it was fixed around the wires but the wires were stuck due to corrosion and age, after I broke them loose they slipped right off, then I routed the new pigtail through the boot and re wired and all went back good as new! so happy to finally understand what that silly little part was for, and glad I was able to reuse it
