Dual Battery Installation

[jmvotto]

If you want something foolproof then get a vsr with a switch. I used a bep and loved it, lots on here used the blue seas with an acr slightly different but get the job done the same.

The isolator is super easy because you don't have to do anything once it's installed. There's a little more to the setup because you have to re-wire your accessories to use the standby battery, once installed you don't have to mess with switches. You can combine an isolator and the switch for the best of both..

I have figure 1 setup..

I think I found this one or one like it for about $35 by searching the net:

Easy to install yourself and comes with directions based on the set up you want. I put everything from the positive terminal on the switch so depending on which battery I'm running everything works. Others like to run a separate battery for the stereo. I just wanted a second battery in case I run dead so I can just switch over. I keep them both charged and ready but you never know.

The biggest difficulty with the install is removing your battery cable connector from the end of the long cable that goes back to the starter. You have to remove the cable connector and install a ring connector so it will go on the terminal on the new switch. I found a part at Home Depot to do this job. Otherwise you have to crimp or solder (or both) the new connector on there. (BTW, there was a huge debate not long ago on what the best way to make this connection is.) Good luck! Oh yeah, I would go to the Perko site and see if you can get the .pdf of the directions. Might make it easier for you.

Sorry I'm not that technical with this stuff so I appreciate all of the information. If my stereo is hooked to my primary battery and that goes dead. Would the stereo work if the secondary battery was on?
