    Another second battery question

    Greetings -

    I've recently purchased a new for me '95 2002 FSLM and have a couple battery related questions - and as it relates to the stereo. First off - it has a single battery, and the stereo is wired such that it turns on both when the key switch is at the accessory position and on postition. Totally expected.

    The question becomes: When I add a second battery with either a Perko or Blue Sea switch and ACR - do I want to keep the stereo wired off the key switch - or do I want to add a bus underneath, wire all the stereo components to that (I want to add a sub, etc), eliminating the key switch and then run the stereo off the house battery and keep the other battery isolated as a starting battery.

    What are the advantages/disadvantages - I can see that by eliminating the key switch I get:

    1. The stereo stays on when going from having the engine on to off. It takes a few seconds for the sirius to kick back in when going from "on" to "acc".


    I've been out a couple times so far - but I'm excited about getting down to Lake Powell in June for a week.

    Thanks for your help - this has been a great resource so far.

    To start with, I would not want my stereo tied to the key, regardless of having a single or dual bank setup. The key is only applying switched 12V to the head-units red turn-on (if wired correctly) circuit, so the head-unit is not actually drawing amperage through that key, again, if wired correctly.

    next, if you plan to add an ACR to the scheme, do no go with the Perko brand switch. For that mater, I dont like the Perko brand any way, but more on that later if you want. The Blue Sea is a far better switch, but you will want the Dual-Circuit Plus switch

    ALL audio gear needs to be connected directly to the battery B- and battery B+ or switch, depending on the setup. No audio should be connected to the helm BUS's.

    Wired correctly, you can have the audio/house loads draw from one battery and keep the 2nd in reserve while at anchor. Theres a couple ways to do this, depending on what switch setup one goes with. The later can be driven by how the system will be used.
