Hey guys, I am having some tough times with my electrical system on my 87 z28 I am concidering using 2 batteries and an isolator, which leads me to my question , Has anyone used them before and how well do they work?

 

I had them in one of my boats. Worked fine for me.

 

ok well here's what i had planned for it . YOu might have done this on the boat not sure but I was going to use one Battery for the engine systems, and the other for the accesories.

 

im kinda newbish at this. but wouldnt that be a bit of stress on the stock alternator?

 

Stock 105 amp alternator works fine for my set-up with two batteries and isolator. Second is for stereo which includes a 1400 watt amplifier. With the car running, I almost always have over 14 volts at the stereo battery, car battery is normally just under 14 volts (I have digital meters hooked to each). You may find more info in the car audio board on the two battery set-up.
