I'm working on a detailed schematic of the wiring system for our newly purchased '88 Pearson 31-2. Everything on the boat works well and it is in mint condition - previous owner took excellent care of the boat. Here's the problem - battery switch appears to be wired wrong. Just want to make sure I'm not missing something obvious before I change it as things do seem to work just fine. Battery #1 positive is connected to switch position #1, Battery #2 is connected to switch's "both" position and switch position #2 seems to be the output from the switch. Also - when I totally disconnect battery #1 from the switch NOTHING works. Battery voltage levels are fine. Everything else seems normal; connections from batteries to engine and battery charger, etc. Can anyone think of a reason why one would wire a battery switch this way? Thanks!
