Truck: 2000 4runner w/ 250k miles
Batt: 4 year old red top (i know some hate them)
Alt: ~150k miles on it (replaced with OEM)
What is going on: very randomly (sometimes goes for months with no problem) the batt light comes on and no charging is taking place. It then will literally "fix itself" and then recharge, batt light goes off and all is well. Then it will resurface and the light comes back on and hit repeat....fixes itself.
Batt and alt test good. Batt terminals are clean and connected well.
My thought is that there is a wiring issue / bad connection somewhere. My plan tonight is to go through all wire connections, clean and ensure they are secure, check neg ground off batt, etc.
Am I missing something / going down the wrong path?
It just doesn't seem like a bad batt or alt since it will recharge for several weeks it not months. I'd think if bad batt or alt, I'd just be stuck with now power.
