What style battery switch is in your boat?

Recommended Posts

Do most of u have a 1/2/1+2 switch or just a 1/1+2 ?

I had an ACR installed although when on bat 1 it's not charging and the battery runs down, if I leave it on combined they both charge.. 

Seems like this is backwards.. 

Also I would think it's a terrible idea to combine in the event bat 1 goes dead... Combining may draw the. Good battery down and bad up to a level u still may not be able to start a boat.. similar like a tiny jump start battery where you sometimes SOL unless u disconnect the battery and jump only from jump pack as not to draw down the jump pack/battery.. 

Seems like the switches should be 1 or 2 or combined? Not 1 or combined

I may have a bad ACR also as it doesn't seem to be working. Had it installed just seems odd..  Also wondering if my bat 1 is on wrong battery? I would think bat 1 should be on alternator, instead I have to run combined now.. led on ACR I can't seem to get it to work.. so I think it's bad if this is possible? And surely Bat one should be on alternator.. maybe the selector terminals are flipped?

In reality, its ON and COMBINE. When ON, both banks are in use and connected to their perspective loads, not just bank 1.

Regardless of which switch style you have, if an ACR was added (should have already had an ACR if the have the OFF/ON/COMBINE switch), both banks should get charged. There are many way to incorrectly wire both switch types, when incorporating an ACR.  

I would start by ignoring what ever switch you DONT have, and focus on the style you have and how its wired and diagnose why both banks are not charging.

I have an ACR only. No switch. In the rare event that the starter battery goes dead (never happened) there's a small Crescent wrench in the glove box to switch the pos terminals.

No thinking, nothing to remember.

Draw a picture of how it is wired.  No led sounds like the ground is not installed to the acr. 

I checked this briefly it fwas not connected.then I did it flashed then no longer does.. and does not charge when on bat 1 only.. will make diagram when I look closer
