Hello! I did some searching here on the dual batteries setup, and most questions were related to running auxiliary electronics (sound systems, motor home appliances etc.).
My car's problem was always related to starting the engine. I am running a HEI, ministarter with a Delco 75Amp alternator (new from Napa). The battery is a 700 crank. amps, the biggest I could find at WalMart. I can turn the engine a few times just fine, then just click. So if the car sat a week, there is no fuel in the carb, I am most guaranteed to be stuck. A few revolutions to get fuel from the tank, then not enough juice to fire it up. I am running thick cables from the battery positive terminal directly to the starter, and a few cables for the ground (same gauge). There is no heat soaking issues
I have a Dodge diesel truck (1994) with a dual battery setup and it fires up just fine even after 5-10 minutes of cranking. So I would like to install a smaller battery in the engine compartment (I have room in the front) with the voltage sensing isolator for the sole purpose of starting the darn car. As you can tell, I am really fed up with it - I'd like it to be reliable.
Would this setup work for my purpose?

I want to use both batteries to crank the engine. Is this doable? Does the Dodge system work in tandem or one battery at a time to crank?
Your input is much appreciated. Merry Christmas to all of you!
Thanks,
Denis
