I have a 94 Mazda B4000 ext cab 2x4 and it runs fine but is killing the battery. I drove it to checker, they tested it and the alt failed. So I removed the alt, took it in and tested it out of the truck and it passed with flying colors. So I put it back on the truck, jusp started the truck and the new battery is down to 10.5 volts even while running. I tested the output wire on the back of the alt and it is not puting out ANYTHING!!!!!
So, my question is where do I look now. Alt tests good on bench but will not charge the system in the truck. Do I have a bad PCM? is there a sensor somewhere? What am I missing
Thanks in advance
