Obviously yours is not exactly like this but this is the basic schematic you are looking for. Thanks Tiger! Question: Looking at your diagram, the left engine switch has a short jumper wire from line 1 to B2 on the house switch. Does that wire connect all the batteries only when the switches are in the "emergency" position?

It would connect 1 Boat battery to the house when the house switch is in parallel, or if both were in parallel, all 3 would be connected.

Obviously yours is not exactly like this but this is the basic schematic you are looking for. Here's a drawing I made of my system yesterday. It was made looking at the back side of my panel while still connected, so the bottom of the drawing is actually the top of the panel when installed in the box. I hope this make sense. When I compare it to you drawing you posted above, I can see a difference: Engine Battery 1 has a wire going to House #2. Please feel free to add you comments or questions. Here's a diagram I found that shows how to incorporate 2 VRS+2 switches for a three battery system. Is this a better way to go since my system seems to be slowly drawing down the House battery when it is sitting for a long time without a charger connected?

You have answered your question. Find the difference between your drawing and my drawing and fix it. Sailfish specifically told me your drawing would draw down the house battery. Its odd you are having issues with the engine batteries. I suspect there is something else going on somewhere else. Check for connections directly to those batteries. Also, you could just have a bad battery. It happens.

Hi Tiger, I inherited some cable mess in the battery compartment and trying to sort it out. I have the 2008 23 express with 2 starter batteries (crank) and one house (deep cycle). Two on/off switches and two VSRs. You posted a diagram of your setup in this previous post but it is not visible. Is there a way how you can repost your setup? I need to verify and correct some of my current cabling and do not understand what really happened here... Any visual help is greatly appreciated. My current setup: Pictures show battery compartment with starter battery 1 on left, starter battery 2 middle and house battery on right. (I am not sure if the battery types (crank or deep cycle) have been placed and used correctly, since a positive cable from starter battery 1 on the left side goes to the breaker (house load) and then the cable goes towards the helm. Battery starter 1 was connected to battery house with a pos to pos pole cable and a neg to neg pole cable. (not sure why but this setup might be to support my windlass). Both outboard positive engine cables go to port/star switch. Then from this switch two positive cables go to started battery 2 positive pole. The negative engine cables from the outboards go to battery 2 and battery 3. any insight and correct setup highly appreciated thank you Attachments:

Talked to Bluesea and had a very pleasant and helpful conversation about my concerns. They provided the drawing below and recommended looking at this below diagram as a starting point. assets.bluesea.com/files/resources/instructions/6346.pdfThis is a very good starting point and can be used as is if you do not let your boat sit for months since the VSRs or ACRs may drain the batteries to a certain degree. If you have the boat sitting for month (i.e. mooring) and want to avoid the draw from the VSR or ACR you want to connect the wires VSR to the load side of the engine side switch.

debating the option to skip or disable the VSR functionality altogether since the outboards each have a charging cable and an additional isolator cable. With this setup you may charge all 3 or 4 batteries when running the engines and there is no need for voltage check and VSR functionality. Would simplify the cabling and the switches wiring.
Any concerns about this?
thanks

My stuff is nothing like yours as mine is all in the console. I see no reason to use the VSR if you can wire the aux to your hours battery. Also if you use a multi-bank charger at home while the boat sits, that will charge them all individually. I went back and looked through the posts and my pictures are up. No idea why YOU can’t see them. You should always post a new thread. Someone would have answered you a long time ago.

Following up on my original post about the wiring of the factory battery control panel with one VSR. I found last summer that while slow trolling with only one outboard running, the house battery was only charging while the port motor was running. After talking with BEP, this winter I removed the factory panel and installed a BEP 717-140A-DVSR. It is designed for twin outboard boats with three batteries (house+port engine start+stbd engine start). It charges the house battery from either (or both) motors. I used the factory box, but had to fabricate a new face panel (template included) with holes for the switches and VSRs. The unit came prewired with easy to follow instructions, so all I needed to do was connect the engine and battery wires. Check the BEP website for details and specs on the unit. Here's a view of the finished installation. As a side note I have a shore powered battery charger with individual charging circuits for each battery while the boat is at the dock.

This is not a VSR related issue. I think what you have is an error in wiring at the back of the switch. My thought is that the starboard engine wire is on the same post as the battery lead. A quick test to confirm this is to pull the positive cable off of the battery for the starboard engine. If that solves the problem then all you need to do is move the engine wire to the switched side of the switch. I wasn't able to pull the switch part number off of the photo, but I believe it is similar to the Blue Seas 5511e. I've attached a pdf for this switch. Good luck with the new boat. This is old, team ruby a great guy he just up and went missing one day no explanation. View Attachmentt
