Battery Isolater Help

[tcullen1]

I have a couple ?'s with installation of a pac-200. I have stock battery and 2 batteries going in rear. 1st can I use the remote turn on lead as the "accessory/12v on"? 2nd the rear line is fused with a 200 amp anl going back, now the other line going to front battery, does this also need fused? It is a very short distance from Isolater and stock battery. If I cannot use remote turn on lead, would the "RED" wire of my head unit work, as yellow is constant? Sorry guess that's 3 ?'s lol thanks for any input out there

Are you planning on running your system for extended periods of time with the car off?

If not I'd stay away from isolators.

If you're set on using one then use a relay between your HU remote turn-on lead.

Remote turn ons don't' have much for current capacity so to protect the HU, use a relay.

What gauge cable are you running to the back?

The red wire should be constant power. The yellow is usually switched with the ignition switch.

I used an isolator in the beginning of my build. It really messed up voltage so i wouldnt use one. My back batteries sat at 15v with the car off and 12.2 car running

Wow did not know that about voltage, it was purchased with a box of goodies. So I thought it would help. I never play my system without car on. Just when I am driving. Damn I spent 2 hours re-soldering 0 gauge wire in sections, re-running shit ughhh. Oh well rather have it done right lol Thanks for info everyone!!!!

This is the one I used. Im not saying all isolators do that, but mine did.

I had the same one you are looking at and i had the voltage problem too.. it stole about 1 volt from my system and half of the time it didn't connect the front and back.. causing my back batteries to eventually die.. i wouldn't recommend them at all

i have a pac-200 that is kinda set up weird. i have one in line from my alternator to my rear batteries. reason being is i have a wet cell in the front and two agm in the rear so i ran thru an isolator so when i turn the truck off the rear batteries dont level off with my main battery. but i havent had any problems YET my setup is still new, so im just putting in my experience in. oh and i used the relay from my cig lighter to power the iso.

Thanks for your input, I actually have a wet cell up front and was adding a kinetik hc2000 to an existing spv70 stinger so 2 dry cells in rear. I got the isolater in a box of goodies when a guy on local CL was selling all his wiring (stinger 0g, dist blocks, etc..) He was done with huge systems. So I had no manual and got dif ways to hook it up online. So I posted this thread. I have already removed it and just ran my set up like this, batt....fuse.............fuse....kinetik....spv70.....ground. Now my question is am i in danger of running a wet, and 2 dry w/o an isolater??????

[Ratski]

The danger you will be in is that wet cells and Agm charge and discharge differently. You may suck down your rear battery and your front wet battery may not have been sucked down as hard so your Agm will pull from the wet cell and drain it trying to recharge itself.

This is my understanding I could be totally off but I have heard both ways w/iso and w/o iso but without they always have the same family battery

i have that pac200 and i had to take it out because the loud clicking all the time didn't like it
