P0620 code on FORD which I guess would be the same as MAZDA. Alternator is putting out 14.1 but computer says "Check Charging System". I found that all three wires to the harness that goes to the alternator exposed. I'll try to clean them and solder them, then clear the code and see how will work out. I am 100% sure that this is the problem.
