Well I'm not sure that I have solved it but I finally did get the alternator to start working. In addition to the 12volt ignition wire to excite the alternator, turns out the only way to get it going was to also excite the positive battery cable coming from the alternator to the center post of the isolator. I accomplished this by making a short 12ga jumper wire running from the lower isolator post, the coach battery connection, to the center post. When this is done the alternator kicks in and is putting out almost 14 volts at the battery and at the volt meter in the dash. Looks like everything is working fine, dash A/C, lights, wipers, etc. My understanding is that once the alt kicks in, it stops the flow from the jumper wire. This is the only way I have been able to get it working but am concerned that I might be creating another unforeseen problem. I will try to attach a picture of the isolator and jumper wire
