Working on a simple drawing to trouble shoot the section the Gen Light is wired to. You would not believe how many parasitic leads are involved. The one brown wire from the regulator is tied to Gen Light which has roots in the Brake Light, Temp Light, Oil Light, Fuel Gauge, Fuel Sender, Ignition switch and Fuse Panel......Which feeds............
I did some testing on LED's (see LED Post) that I am going to use in the Instrument Cluster.
I am now learning about Fuel Guages and Fuel Senders as it is tied to the +12v the Gen Light is on.
