Battery Not Charging

[Chong Hang]

Got a 07 4runner that would start and run but once i stop the battery light will come on and the vehicle will die out. I replace alternator and battery and new belt and it ran for two days and having the same issue again like it’s not charging the battery. Now it won’t start unless I jump start the battery than if I stop the battery light will come on and car will stall and die. Please i need some help. It’s my parents car that I’m trying to help them fix.

You need a wiring diagram of the charging system.
Simplest way to start …. check all fuses, power and ground connections connection
Many newer vehicle charging systems are controlled by the ECM / BCM or other types of monitoring module(s)
It isn’t as simple as in years past.
