Evening everyone,

I Have a LT1 in my blazer and the alternator is brand new so is the battery. It is not charging. I have the battery wire hooked up and the connector with the one wire going to it hooked up also. This wire going to the connector doesn't put out any voltage hence I guess the alternator is not getting turned on. What pin is this wire at the pcm so I can test it there? Also any sugguestions?

Thanks in advance for help
