Charging system
1990 Mazda 626 lx
I have 12.53 Volts at the battery while the engine is running with no loads on. I have Replaced the alternator, battery, battery cables. I also did a resistance check from the positive alternator lead to the battery and everything specs out... Please help if you can

I would take the car in for a proper load test. That's the only one that matters.
You could be reading 13.7v and still have little/no output current under load. Static voltage tests tell you very little about the condition of the system itself.
How sure are you about the meter you are using to test voltage? Could it be out of spec?

I had the alternator out and had it load tested at 2 locations. Both said that it was putting 14.1 volts under load... gonna replace it anyway Just picked one up and will get it in tomorrow. Charge light is good. but will keep everyone informed on here. Thanks for your help
