Starter relay keeps going bad

Vixen just did this the other day. I pulled the plastic plug off the relay and the male terminal on the relay and the female terminal in the plastic were all green with corrosion. I cleaned the male terminal with a small wire brush and dipped the female terminal in some coke for a few minutes and cleaned it with a toothbrush. Hasn't done it since.

Same here almost . I had a ford relay on mine when I first built it ,''complete rewire with an E Z kit , which I had to change the connections to mopar from the chevy stuff that it came with, the ford junk died suddenly in the garage after about 6 months, installed the orig. relay that came with the 68 fastback in a box, working perfecty for about 10ish yrs now. It did refuse to start one morning when leaving the mens prayer breakfast, was a loose 52 yr old connector , replace it w/ another 52 yr old connector that fits titer , all good !
