My jeep has been on the road for some time now. I have never had any performance issues at all until the other day when the battery charge indicator gauge began fluctuating. While doing so, my headlights would dim, and the engine would sputter as though it was running out of gas. I limped it about four miles, before quite suddenly, everything returned to normal and I was able to race along home. I was gonna chalk it up to a bad alternator, or maybe a tired battery. But it's sudden recovery has me thinking it could be a wiring issue. I haven't tinkered with the wiring in a long time, so I can't quite place what the issue really is. Can anyone help me understand whats going on here?
