So that's one issue fixed I also changed the ethanol map so no more engine light.

But I still have the alternator or regulator issue already changed it 2 times and the last one doesn't charge with regulator cable connected once the engine is hot. With regulator disconnected it charges while driving but not at a stoplight for example.

The first replacement the alternator had same issue stop charging when hot except I could make it charge again by accelerating to high rpm for 1-2 seconds (until next time I stop and restart engine -had to rev it again-). This one triggered battery light flickering but the second one no light. First one I could remove negative battery cable and engine would not stall the second one it stalls

Can it be the faulty aux fan that I disconnected? Something else?
