I recently noticed that the electrical systems on my 1976 Cat 27 were becoming more and more ureliable. Finally the spreder light went out so I pulled the panel to find a bunch of corroded connectors. I've gotten everthing to work again but the spreader and anchor lights. For the life of me I can't figure out what is wrong. The wiring that I encountered was not factory original. From what i can tell, the yellow wire in the main trunk powers the spreader light. There is a light green wire which I think is the spreader ground wire but I'm not sure. Does anyone out there know how the spreader or anchor lights are grounded? Do you have any suggestions what to do if I can't salvage the original wiring and am force to replace it. Thanks for your help, Seth sethandeileen@home.com
