I recently acquired a 1994 Hunter 40.5 and have been trying to figure out the electrical charging system and wiring in the engine compartment. There’s an alternator regulator (mfg by Cruising Equipment), a black box with a red button (fuse?)marked “135”, and a battery selector switch (1,2, all, off) , all just above the front of the engine. The box with the red button is marked "Leave in '1' position."And inside the engine compartment on the port side, there’s several round instruments (?) and a rectangular box—--all of which have heavy duty red wires connected, so I expect are part of the charging system. Is this a stock setup? What are these pieces of equipment and how do they operate together? The boat has a engine cranking battery and 2 X 8D house batteries. There’s also a Cruising Equipment 2 - battery bank monitor at the nav station. Which batteries do the “1” and “2” on the battery bank monitor refer to? And when the “low battery” flashes on the battery bank monitor, how do you know which battery its referring to? There’s also the main battery selector switch in the starboard lazarette. With three batteries on board, does the “2” on the battery switch refer to both the 8D house batteries, and the “1” refer to the engine cranking battery??

(HERE ARE SOME ANSWERS, ALAN.) I recently acquired a 1994 Hunter 40.5 and have been trying to figure out the electrical charging system and wiring in the engine compartment. There’s an alternator regulator (mfg by Cruising Equipment)(THIS IS AFTER-MARKET), a black box with a red button (fuse?)marked “135”,(THAT'S THE FUSE) and a battery selector switch (1,2, all, off)(MY SELCTOR IN THE ENGINE COMPARTMENT IS ON OFF ONLY. THE ONE, TWO, ALL, OFF IS IN THE STARBOARD WING COCKPIT LOCKER) , all just above the front of the engine. The box with the red button is marked "Leave in '1' position."And inside the engine compartment on the port side, there’s several round instruments (?) and a rectangular (THE RECTANGULAR BOX IS AN ISOLATOR ORIGINALLY TO CHARGE BOTH THE HOUSE AND START BATTERIES)box—--all of which have heavy duty red wires connected, so I expect are part of the charging system. Is this a stock setup? (THIS IS NOT A STOCK SETUP. I WOULD CALL AN ELECTRONICS GUY OUT TO GO OVER IT, OR CONTACT THE ORIGINAL OWNER TO FIND OUT WHO DID THAT INSTALLATION) What are these pieces of equipment and how do they operate together? The boat has a engine cranking battery and 2 X 8D house batteries. There’s also a Cruising Equipment 2 - battery bank monitor at the nav station. (AGAIN, THIS IS AFTERMARKET AND REQUIRES A TECH TO GO OVER IT OR A CONVERSATION WITH THE PRIOR OWNER) Which batteries do the “1” and “2” on the battery bank monitor refer to? And when the “low battery” flashes on the battery bank monitor, how do you know which battery its referring to? There’s also the main battery selector switch in the starboard lazarette. With three batteries on board, does the “2” on the battery switch refer to both the 8D house batteries, and the “1” refer to the engine cranking battery (GOOD LUCK, ALAN. YOU WILL NEED SOME LOCAL TALENT WITH THIS. RICK D.)
