I have an 89 Sea Nymph and I think the wiring is shot. Everything seems to work when it wants to. This winter I plan on rewiring it when I replace the wood and carpet. I bought some electrical contact cleaner but that does not seem to work. Everything is a dull gray. What should I clean it with or do you have any other suggestions? Trolling motor, fishfinder and navigation lights are working intermittently. Whats the best way to clean the fuses(glass) and fuse box?<br /><br />Thaks,<br /><br />Rick
