Getting closer to getting my car on the road after 2 years of restoration. Encountered first bump on the road of proably many. While preparing to start the engine, noticed a live feed thgrough wires wven with key on off. After testing wires from front harness, I found terminal 4(brown wire) on regulator is grounding.... is this an issue? Wiring diagram show this brown going straight to fuse panel so I'm not sure its supposed to be grounded.
