Ok,inside the Diehl case is a Dynamo, the 3 wires coming out are going to a small aluminum plate. One wire goes from that up into the instrument area to the power bus. It appears that the aluminum plate item must be a rectifier, but I do not see a regulator, just a shielded wire from the rectifier to the power bus. Any idea's about how this worked without a regulator? Or should I just buy a regulator and rectifier and diode and wire this system correctly? Which regulator, rectifier, etc should I buy? --MIKE
