I am having the same problem with my 04 Mazda 6, 2.3L 4cyl. I had it checked at Advance Auto the other day. Battery good, starter good, but alternator putting out 0 current. He told me to check all wires first before changing anything. It started after driving from NC to Maryland Sunday night. I got home and the battery light flickered. Drove it to work on Monday but when I went to go home, battery light came on and stayed. Went to pull off and car went from 1st to 3rd and would not downshift to 1st when I stopped. I had to take off in 3rd gear. I switched the car off and was now in 1st. Also, it would not manually downshift to 1st either. CEL (Check Engine Light) also on - Coolant Temprature Low (that will be another post because I changed the Coolant Temparature Switch and CEL stayed off for about one month).
I read on some other sites that 1 guy changed alt 3 times and CEL was still on so I don't want to hane to go through that process. Is there a sure fire way to determine the problematic source? BTW, not good with volt meter!
