My wife has a 1999 V6 Mustang that has, all things considered, been remarkably reliable (more reliable than some Toyotas I’ve owned in fact).
However, today the power went off momentarily while we were driving, and then at a red light it shut down entirely. A few moments later it did restart, although neither one of us had done anything other than try the ignition again. I checked under the hood and the terminals on the battery cables were covered in green corrosion gunk. I think the terminals may need to be replaced and possibly the cables. However, I’d like to hear what the community has to say because automotive maintinance is not my strong suit, and I might be missing something that might be not so obvious (or something that me be very obvious, as I said, this isn’t my strong suit).
In the mean time my wife has cleaned the terminals with the usual Sodium Bicarbonate mix. I’ll try to post a picture to give everyone an idea of the level of gunk.
