I’m curious to see how your batteries are wired for 2 cranking and 1 house with 2 battery switches and 2 VSR’s. The new boats only have 1 VSR. I don’t think mine was ever right from the beginning.

Do you have one VSR or two?

2 of my batteries are wired to one switch for the engines and the other battery to the house switch. All batteries are wired in parallel for charging and isolation regulated by the VSR.

I am pretty sure mine is wired similar to this. Which allows the vsr to isolate batteries when needed for charging or if it detects discharging to protect the other batteries.  |

I have been looking at this diagram but mine is nothing like that. I think I have it figured out. Looking at the neeer 290 owners manual which has 1 VSR, it only has 1 battery charging the VSR. I just need to run a jumper from port starting switch to one VSR and a jumper from starboard switch to other VSR. And a jumper from the house switch to both VSR’s.

I’m just not positive where the jumper goes on the house switch for both VSR’s. I see where it goes for a one VSR system. I’m assuming they both go on the lug where the power comes in from house battery.

Yea, I can't help much since I only have one VSR. Sorry...

View AttachmentIn this set-up you really only need one VSR to charge your house battery. Having a second one just provides redundancy, which is never a bad thing on a boat. With one VSR, if you lose the engine that is connected to the VSR, you won't be charging the house battery when returning to port on one engine. So, you might drain your house battery when returning to port in an emergency. If you have two VSRs as pictured, you will always be charging the house, no matter which engine is running. |

That’s my understanding. I have it all working properly now.
