I've been slowly working on my Dad's old boat. It has been a long and arduous process but I think finally after some touching up I am ready to move on to phase II. So Phase II is the electrical and have to admit I'm clueless. IS it recommended running new everything? I have a lot of the old stock parts and a book on it but no wiring diagram for the actual boat. I read some other forums and they suggested I do a homemade wiring diagram first while leaving everything in stock. Any advice and expert knowledge would be greatly appreciated.
