Dual battery kit chosen enough?

[tdonoughue]

Glad you got it done with some good results. Looks like quite a list you have ahead. Wait. Let's see how we can add to it... Need a boat lift? Sea Deck? Refrigerator drawer?

I'm here to help.

The joys of boat ownership got everything hooked up put fuses on the ACR to the batteries ran all the new electrical to the new amp and stereo system everything works great hooray.

I did not clean up my wiring yet just in case of these issues

Go to turn the engines on ....engines fire right up!!? go to turn the engines off starbord engine will not turn off when I turn the key to off position. I didn't have that problem with the old on/off switch, what the covid heck!!!???? No problems last year. maybe it needs a different switch? Help? completely confused, pretty tired and defeated. In the words of Forrest Gump I think I'll take my ping-pong paddle and go home now.

 

[tdonoughue]

Wow. That is a good one. I was going to say you have two wires swapped on the switch.... but I can't figure out which two would produce that result.

So I am going with a short. My bet is that you have one of the wires shorted out on the switch (bent it to touch off the switch or something), so that 'off' is always 'on'.

Grrr..ok..start digging tomorrow..i.did pretty big audio installs in stadiums to.pay for college. I'm pretty anal on my wiring....but. I'll.start diff ng tomorrow. Do these boats keyed on off switches ever go bad? It is a 2006 boat..that last season. Worked flawlessley for me

 

[tdonoughue]

It's possible, I suppose. But I have never heard of one yet going bad.

Plus, I have learned that when something like that goes wrong right after I was just working in the same area, it is possible that the 2nd thing just died, but much more likely that I killed it with something I did...

 

[marcham]

Most likely what changed last caused the problem... did you use the ignition override for the acr? If so, start by unplugging that one.

hey guys thanks for the advice boy that's almost philosophical on both of your part it was the last thing I touched and had nothing to do with the key switch. just like all things in life some of the things we touch impact the things right after it.

So what I did on the four posts there are two ones and two twos and what I did was put the accessory on the same bolt as the engines. I put a secondary accessory for the stereo on number two assuming that it would follow the same way that my on/off switch would.

Well I read what both of you wrote looked at it again looked at the diagram again and realized my own ignorance... fixed it boat turns right on, boat turns right off life is a happy place.

so the new stereo systems installed the new amps are installed the new wake tower speakers installed with remote access the new add a batteries installed next up I'm going to tackle the perfect pass that showed up a couple days ago.

This forum is so great to help each other out I've been able to help a few other people and now a new lesson learned. Glad to be done with this project that looked pretty simple but took me a couple nights of thinking it through

@tdonoughue and @Milwmarc - do the red/positive wires from the ACR go to the Blue sea switch or do they go to the batteries? The install instructions on-line show them going to the batteries but I think I have read ACR positive to Blue sea switch. Then, blue sea switch positives to positive on each of the batteries (with fuses).

Thank you

 

[tdonoughue]

I have mine wired as the second diagram on: Battery Management Wiring Schematics for Typical Applications - Blue Sea Systems

The ACR should be wired to the positives of the two batteries. But note that those two positives are wired directly to the switch, so you can connect there as well and it does the same thing. So electrically they will both work the same way. Make sense?

That makes sense and I’ll do that since that is what I see in the diagram.

@tdonoughue - I have black cables from the engine that in my OEM, single battery setup has both (2 engines) cables connected to the negative of my battery. Where do these cables get connected with the blue sea setup? Thank you

 

[tdonoughue]

Same place. They don't move or change. The ACR and switch are only messing with the positive side. The only part with which you deal with the negative is to add that black wire from the ACR to the negative (either battery--they should be tied together on the negative side).

 

[Milwmarc]

Just a follow up..all the advice I gave is great and all working perfect. So much so I may not be charging my batteries as the house anymore ..as I just bought a lake lot and now have to reconfigure , figure out battery mainatanance on the slip tillminget shore power.

Great thread and discussion very helpful
