Starter motor wiring troubles.

[Brad]

Hello Beddy people.
I was trying to get the wiring right to get my Beddy running again. I ran into trouble with the wire from the alternator to the starter. The battery light would come on when the battery was connected even though the keys were not in and then it would not start. I unattached that wire and the light stayed off but still no starting. Could it be a dead alternator or is it something wrong with the connections. Any hints or suggestions!
