Wiring Question

[ScottM]

To all 23' Sceptre/Tsunami owners,
On my '82 there is a nav/anchor light mounted to the top of the windshield and the wiring runs through the frame to a point where it passes through the deck and into the cabin to the wiring panel. The wiring is corroded and looks as if it shorted out and some point. Does anyone know how to re-wire through the windshield the way the factory did it? I fear that it requires pulling the windshield apart, but perhaps one of you has a suggestion. Maybe Mr. Potter knows even though this is a CSY-era hull?

Thanks,
ScottM
