Anyone added a second battery?

yeah, that's a simple diagram missing the alternator wire that I showed in the scanned in diagram i got with the kit. All makes sense now though.
 
Glockit4...Is that the system you have.. The Blue Sea Add a Battery? I just ordered one for my 220 SD. If so, I would like to know details of your installation, if possible. Also, does this let you "set it and forget it" or do you have to manually set your switch so that the starting battery is only used for starting?
 
Hmmmm, maybe you should take the boat to a local shop or MM.

See my post after this. Turns out that wire on the schematic was the alternator wire. Didn't realize that. Got it almost finishsed. Just need a few more lug connectors and I'll be ready to finish it up next weekend.

My thoughts exactly. For the few $ of installation costs, to me it was a no brainer to let someone else do it right and save me some time to do something else enjoyable. I was also afraid of...

I just feel if the guy cannot understand the schematic, how in the hell is he going to be successful doing this project without a headache. BTW I am still lmao at the pic.

I'll admit I am poorly educated in the way of electronics/electrical work. Although the battery install seems easy, I know enough of myself to just let a pro do it. Same in my home. I can pretty much build a home from top to bottom, but electrical and most plumbing I leave to the pros.

Both the above can cause a wicked amount of damage if you dont know how to do it.

I know what you mean. I replaced every light switch and receptacle in my house because my wife wanted to change to white. I thought....no problem. it took me a full day to do it.

Well... while you may think I don't know how to read a schematic due to my misunderstanding of their graphics, I have no problem reading this one now that I understand what their picture is supposed to represent. My dad is an Electrical Engineer, and I've consulted with him on my plans, so I am not worried about my install. Blue Sea should have labeled their schematic a little better or I wouldn't have had any question as to what it was saying. The second the Blue Sea tech said that the solid wire was the alt, I figured out what their picture was supposed to be.

Haha yeah. I replaced every socket in my old house. It was built in the 60's I think and anything you plugged into one just fell out. Thought it was going to take me about a half day but ended up taking a full one without many breaks! Also reaffirmed that you can't trust the way houses are wired up after getting shocked... always keep my elec meter handy now!

yeah, i understand the risk and have seen boats on fire, but I also enjoy doing things like this on my own. Not doing anything I'm not entirely confident about. That's why i'm here to get more info :).

Yes, that's the system I bought and am hooking up. I am following this schematic (top right page). Note that the image in the bottom right of the diagram is the entire motor and not just the starter as I thought it was. The bottom wire going from battery directly to the picture is the alternator wire.

Totally. Our wiring was done in a very odd way as well, though built in '79. I have a good friend who is an electrician, so I call on him for pretty much everything (except ya know, little stuff like I put my own lighting fixtures up and stuff).

I am just dumb when it comes to that stuff.

Whatever ya want to do is fine with me. :smt001

Just double check everything, not worth a fire or burning out other electronics. Tell ya what, even if I knew what to do, id be afraid to do it! lol. I will rebuild anything mechanized, but for some reason, any little thing on the boat besides the basic maint of oill changes and drive fluid, Im bringing it in!

:). I trailer the boat so I have plenty of time to work on it in my drive way and test it all out. Adding an extra battery and stereo really is no more risky to me than doing the same to a car. Test it all out before you take it out on the water and all should be fine. Understand that fire on boat is more dangerous than in a car though since you're isolated to water. Proper testing should be fine though.

The best way to do it is with a combiner and a Off/On/Combine battery switch. You will need one of these switches from Blue Sea http://bluesea.com/category/1/products/5511e
and you will need a battery combiner. Blue Sea sells an "add-a-battery" kit that includes a combiner but their combiner is not too reliable. We use the Blue Sea 5511E switch with a Yandina combiner. Here is a link to it http://www.yandina.com/c100Info.htm

Jim can you elaborate on the reliability of the Blue Sea Combiner? I like the whole kit idea and now you have me thinking.....Can you Pm me some prices? Also including wires? only need a few feet:thumbsup:
 
Well I am almost ready to hook all of this up. I'm just waiting for my two inline 4gauge fuses holders to come in so that I can hook up the relay.

Question on installing this. I am planning to drill holes through the starboard (i think) that separates the engine from the left and right sides of the engine compartment. My only concern doing so is that this stuff doesn't seem to be the strongest stuff. I'm not going to screw it in, going to drill all the way through and use a pretty good sized washer with nuts and bolts.

Anyone see a problem with that?
