Dual battery set up - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I did a search on this subject and found some info but looking for more. I noticed some set ups have isolators and some have selinoids. Is one better than the other. Also in the earlier post someone had mentioned there is a good schematic in the factory assembly manual. Any way to post that? If you have dual batteries whats your set up?

I have a 63 C20 with 10' camper on the back. I run a isolator, that way I charge both batteries at the same time. A solenoid would allow you switch batteries, only one would be active at any time. Need more info as to your application in order to recommend one or the other.

I use an isolater and a solenoid. The isolater allows me to charge both batteries as well as run a wire to the trailer to charge that battery, too. The solenoid allows you to run your main battery dead; hit the solenoid switch and you have an automatic "jump". Also if you are jumping some one and hit the solenoid switch, you are effectively jumping them with two batteries.

Thanks for the info. I have a 72K5 and I basically want a dual set up for camping so I can power up accesories and still have a good battery for starting the Blazer
