Johnny,
I own a 2018 Chevy Equinox with around 50 K on it. Last fall I got a call from a good friend that the hospital up here was transporting him immediately to the IU Hospital in Indy, 150 miles south. They were going to do emergency surgery on him that night or first thing in the AM. I am the closest thing he has to a next of kin. So I headed out of here that way. At 4:30 AM on some side street that did not look to great, my car quit and everything electrical went dead. Nada, Nothing electrical worked. After 10 minutes with me under the hood with a meter checking things like the 5 very large fuses plus the battery cables at the battery, all read 12.7 volts. Then it started up and every thing electrical worked fine again. I later cleaned both battery cables at the battery that looked perfect before I cleaned them.
Seven months later, which was 2 weeks ago, I was going to another hospital up here because a Doctor friend was having brain surgery. My Equinox did the same thing again. After 5 to 10 minutes with the meter it started and I finished my drive to the hospital. No error codes, no bad meter readings, no nothing. Oh well another 7 months from now I will get another shot at this I guess.
Wrong, Last Saturday I was 100 miles away and it did it again. That 7 months turned into one week. I got it started after 10 minutes and drove back home. On the way home I stopped at a Speedway for a hot dog and when I came out it was dead again. You know the story again. All things read good except nothing worked. 10 minutes later I drove it 6 miles home and parked it in my garage. It would not restart there. In the morning it started just fine.
Last night late I decided to clean and polish everything I could find. I did the grounds first. Then the positives which all go to a fuse panel mounted on top of the battery. One 2 gauge cable in and 6 cables out with 5 going through fuses from 40 to 500 amps each. I had to remove the panel to get to the internals to unbolt the 7 wires. The bolts were all tight from slight oxidation in the threads. The cable I worked on last was the main one going to the battery. That nut turned differently than the others. It was hard to move. Upon removal of the lug from the stud it looked good. But there was a little black 1/8"spot on one edge and a matching black spot on the plate where it was bolted to. That was the only contact point for the entire lug. I have owned this car since new and no one has been in there working on this area. This was a case of someone did not tighten the nut properly 5 years ago when the car was built. I cleaned (polished) and anti-Ox greased all connections. That has taken care of the problem. I spent hours last night doing this stuff and tonight it runs fine. Let's see if it still works a week from now.
CLEAN, POLISH, AND GREASE.
