AR195s new battery switch

[FattyMatty]

So question. I am putting the dual battery switch in my 195s. I have a wire labeled battery switch, bilge, C, and one unmarked that goes to the engine I believe. Currently I have the “C” wire that comes from battery one to the battery one post on the switch along with the bilge and the one red wire that goes to the engine. Battery two post will have positive from battery 2. The output is where I currently have the wire labeled battery switch. And that wire runs into a harness and fuse I believe. Does this sound correct as far as wiring goes so far? I want to put another red line out for positive from the output post to run to a bus bar.

Can you make us a drawing?

Here ya go.

Thanks.

Can you make a drawing of the stock wiring?

Do you have a service manual? If not you should get one. You need to know what C is.

The bilge pump usually has two feeds, the auto side is fused and is wired directly to your battery this way the bilge pump is always active in the auto mode. The other feed to the bilge pump is the manually actuated one and has its own feed and ckt protection.

I’d also think you’d want the positive from the engine to be connected to the common so no matter which battery is selected it is tied to the engine.

On second thought leave the engine tied to one battery. That way the charging system will always be connected to a battery.

If the switch is a break before make type then you could disconnect the engine while it’s running and this will destroy your regulator rectifier.

Speaking of switches, which switch exactly do you have? We need more information to be able to answer your question.

Did the switch come with wiring instructions? M

Is this a 1 2 or 1+2 type of switch?

C is labeled on one end and house on the other end of the cable. I had a BEP simple on off switch. Now I have a new switch that is 1. 1+2, and 2. All I’m trying to do is move the wires from the original switch to the new switch. The bilge cable was on battery 1 on the old switch so I put it on the same way on the new one. The cable labeled battery switch was on the common post on the old switch so I put it there on the new switch. I put a new cable from the positive battery post on battery 2 to the battery 2 post on the switch. So I don’t have answers to all these other questions about rectifiers and is the switch a break etc. I sent the picture just like I have them wired. I don’t have two positives running from the bilge that are hooked to the switch just the one like it was on the old switch. I’m simply just trying to add a second battery and want to make sure the cables I have are in the right place on the switch. Thanks for your help.

So it looks like you’ve already completed the switch install and wired it up per your drawing and are asking if the way you have it wired is correct.

Then the answer is no, you do not have it wired correctly.

Ok thank you. I will go back to the drawing board to see what I did wrong.
