There are owner manuals for four GB42s in the Manuals section of the GB owners website Grand Banks Owner's Resources
. They are for GB42-488, GB42-682, GB42-966, and GB42-1461. Like all GB owner manuals, they should all have AC and DC electrical schematics in them. The only one I looked at to make sure the manual is like ours from 1973 and has the schematics is GB42-966, but I assume the others have the same thing.
