1985 40 Mainship Wiring Diagram

Hello fellow boaters; I purchsed my 1985 40 Mainship about mid summer and have the boat in heated storage (Canada) to make upgrades this winter. One of the issues is installing another set of house batteries. The documentation I received with the boat is incomplete and has no electrical diagrams. Does anyone have a copy they could send me. Thanks Max.

Real wiring diagrams are for the most part non existent for Mainships. There are some rudimentary drawings for each model but for the most part it is not of much help if you need to trace a real problem.

But adding house batteries should be a fairly simple item. All you will have to do is decide if they will be 6V or 12's and where the placement will not cause a list problem.

Join the Mainship Yahoo group and ask this same question and you will find folks that have done this project on your exact boat.

Working on a 2004 40' mainship trawler with Xantrex inverter. Cannot find the inverter on the boat. Suspect it might be behind the refrigerator. Also looking for wiring diagram of same boat.

Some one sent me a link to mainship manuals. I won't have access to that computer until Tuesday. If I find they are relevant I will send a link.
