My voltage regulator is missing. I did not know what those wires went to until looking at ChadL's blazer this weekend. Also on the alternator, the 2 wire plug and the ground that come out of the wiring harness are not hooked up. There is no place on the alternator for them. There is a seperate wire running from the alternator to the ignition switch. What has someone done to my blazer??? Where can I find detailed info on how the wiring was from the factory. There are so many wires spliced into each other under the dash I can not tell what is what.
