How does this look?

Hello all...I'm installing the battery in the trunk. I've done some research and this seems the way to go? I have a 69 camaro that should run 11's or 10's. I've read some people put a fuse or breaker between the (one wire) alt and battery? I 'll be using 1 gauge wire for this project. Thanks !!!!!!!!!!! A

Re: How does this look?

Looks good and with the circuit as drawn, when the kill switch is off, the engine and accessories quit - good point.

Only problem with this set-up, and you can't get away from it, is the double run of cables from the alt to the battery. You might want to increase wire gauge from 1 AWG to 00 AWG to reduce current losses. If you have 1 AWG on hand, go ahead and run the cables and do a voltage drop check of the cable itself and if less than 0.5 volt loss from one end to the other, you'll be fine. Otherwise, larger gauge may be needed if you don't charge battery in the pit between rounds.

I suggest fuse size of 80 amps.

Fuse type would be of the same style stereo stores install from the battery positive clamp.

Re: How does this look?

The schematic above leaves a lot to the imagination. If you're going with a rear-mounted battery, there are lots of details you'll want to be aware of. If you search the archives you'll see lots of discussions about rear mounted battery setups and recently someone posted a more complete schematic which was critiqued. Ventalation is important. Fire safety is number one and will dictate the location of parts, types of cables, connections, solenoids, etc. I advocate running a separate ground wire equal in size to the starter power wire all the way to the block. The starter is a huge current draw and will roast any inadequate ground. The separate ground will protect your car stereo amps and other accessories from being eaten by the starter. A starter solenoid will prevent a short circuit from shunting full battery voltage to ground. In fewer words -- keep looking for a better schematic and more details. Make a parts list.
