Yes, the black wire that goes to the battery does have power. I have found the problem. The mounting bracket that is shown in my photo was shorting inside the connector block that bolts on to the alternator. The main wire in the block that goes to the battery was a little loose. (Not really firm in the molded block). Upon moving it a little there was no longer continuity between the main wire and this mounting lug. After reattaching everything and starting engine, the check engine light was gone and the alternator was charging. This loose condition in that molded block on the alternator is what was causing the problem. Not wanting to cut off that mounting lug, I simply insulated it before attaching the block to the alternator. I suppose a new cable would be in order, but I have already spent way too much money getting the car back running.
