The problem is the alternator, this is a common problem with some rebuilders, especially the brand Auto-zone carries. The alt checks out fine but in fact it isn't. Get a refund and try Advance or maybe Oreillys.
Be careful when the lights come on the Radiator fan does not work and the car could overheat.
IMO this was a bad design by Isuzu.
