Gold Member Username: OlegSanta Monica, CA USA Post Number: 1287 Registered: Nov-04 | He should. I also heard it's best to use a solenoid to isolate the battery to descrease voltage drop as opposed to using something else. Anyone know about this in depth? Can help S.P.D also. |

Gold Member Username: Nd4spd18Southeast PA Post Number: 2137 Registered: Jul-06 | An isolated battery dedicated to the audio system is the best way to set up an electrical system, short of installing two alternators (often not an option). A real battery isolator (diode based) is the way to go. It will allow current to flow from alt to battery 1, and alt to battery 2, but current cannot flow between the two batteries. Diodes have resistance though, and resistance causes voltage loss, usually about 3/4 volt with these isolators. That's not enough to cause any problems though, the batteries will still charge ok. When using a solenoid/relay, it is installed in-line between the two batteries. The current can always flow from the alt to the front battery. It can flow between the two batteries when the relay is activated. This is not a good setup for a few reasons, one is that a solenoid/relay is not as reliable as a diode based isolator. Other problems (that I don't really want to explain in detail) can be caused by the fact that current flows between the batteries when the relay is activated, depending on the method used to activate the relay. |
