no charge alternator
Hey guys. love the forum and really appreciate all the good wisdom here.
I am working on 06 superduty. (it has single alternator) alternator quit charging and ran batteries down. charged batteries, replaced alternator and still have problem. read all i could find on forum and it seems my alternator is not getting the signal to charge via the small 2 wire connector. the "A" circuit (orange w/ light blue) has 12v all the time so all good there. the "I" circuit (light green w/ red) has 0v all the time. when I put 12v jumper to "I" terminal on alternator, it starts charging fine. looks like "I" circuit comes from the instrument cluster. any thoughts as to where i can find this?
thanks in advance for your help
