Big 3/Battery Relocate Problem/Questions.

[91burb]

So I have upgraded my big 3 with Knu CCA 0 gauge in my suburban.

Battery is in the back of the truck behind rear seats. 2 optima redtops are the batteries. So I have 1 run from the + on the battery to a anl 200amp fuse on the core support and then to the alternator. 1 run from the frame to the engine. And 1 run from the frame to battery. I have the stock wire for the starter attached to the + wire with the alt at the anl fuse.

So when I first attempted to start the truck it turned over 1-2 times and popped the fuse. So I played with it and made sure all grounds were ground clean, shiny metal, good tight connects etc.... and even redid the battery ground and tried again, the truck turned over several more times this try until the fuse blew.

Any ideas what I've screwed up here?

Should I add a run of 0gauge from the starter to the battery behind seat??

Should I just mount 1 battery up front with the starter wire attached here as well as the alt wire(after the fuse) and hook my long run to the back of the truck to the positive reconnecting the 2nd battery? Id rather keep the batteries in the rear if possible just to help the engine compartment look cleaner....

Thanks for the help in advance

when you move the bat that far you need to up the fuse to 300a. Hot rodders make this mistake all the time. And I would run 1/0 fused the same to the starter.
