While doing some electrical work on my '98 H240 I noticed there is no main fuse on the battery- I checked the positive wire as far as it was exposed, including inside the flexible plastic conduit. The wiring diagram in the manual indicates a 40 amp fuse should be there- and my battery location and wiring appear original. I plan to add a terminal fuse block (Blue Seas 5191), but was wondering if other 240's were missing this safety device? Will probably go with a 40 amp fuse, but considering dropping to 30 amp due to my limited electric load.
