Car Audio and Electronics
Sponsored by: SKOB on itunes Discuss sub and speaker setups, GPS navigation, XM radio, and anything else related to car audio and electronics.
My bro-in-law has a conversion van that uses 2 batteries, but the auxilliary battery is missing. I assume the isolator is supposed to keep the two seperate, but I can meter 12v on the auxilliary side where the cables are supposed to connect to the 2nd battery. Which means that voltage can only be coming from the primary battery . . is this normal? I don't wanna hook up the 2nd battery and end up blowing them up

Yeah, deep cycle is used by most for secondary. These setups are recommended usually for massive stereo systems where a few farads of cap just isn't enough. I've always thought it was in vehicles used in sound competitions only.

1993 325iC Pure stock, uh, except for the MOMO Cobra shift knob.
are the two batteries parralell or in a series, or are they totally seperate? btw, a lot of times the meter that reads your voltage, its actually the voltage of the charging system, so if your alternator is working and you have a dead battery, it will read 12 volts....

the deep cycle batteries actually dont give up current as fast as a regular batteries. they are designed more for applications where you need a small draw for a long period of time. they also can be drained until dead and are able to be charged back up with less damage to it than a regular battery.
the isolaters are nice because you can totally drain your battery (parking lot, key off time) and start your car to go home.
Umnitza now provides a mechanic to install all parts ordered right in the box! It's their new "Total customer service program" that will eliminate all the haters and keep incompetents from breaking **** and blaming the vendor! When you are all set simply call INS and they will pick him up free of charge.
This isn't for my car; it's for my bro-in-law's conversion van, which has AC electrical outlets and a breaker box inside, for RV purposes. It was just missing the aux battery, and I wanted to make sure one battery wouldn't simply drain into the other . . guess I'll find out tomorrow
