Looks good from what I can tell, my last chassis was setup like this.

 

Thank you

 

Is it necessary to use a fuse between the alternator and battery?

At the moment I have mine setup with a direct line, have I done this wrong?

 

If you wire the switch this way the car will continue to run with the switch turned off...You need to run the alt wire direct to the battery. Do a quick search theres a few threads on this already.

 

This should help

 

i have the same question

 

Joel,

Appreciate the wiring schematic above. If you could add the amperage of the two fuses and awg size for the wiring, It would be even more appreciated.

 

That will depend on the circuits of the car - but I will typically recommend a 150A circuit breaker for the battery.

The starter motor can draw 125A+ with enough compression, the starter solenoid generally draws 10-15A. Depending on the type of cable used, 4AWG is normally just fine for the BAT +, BAT -, and starter motor. If the car is still on an alternator and has say (2) fuel pumps, water pump, larger fan, etc - 8AWG may be used.

 

Thanks for the help. I have to make some adjustments.

 

Heres my final draft before i start cutting wiring. Look correct?

Battery to alt*
Battery to 1 side of cutoff

Starter to other side of cutoff
Fuse/switchpanel to same side as starter on cutoff

 

I'm not sure what indicates a 4 post cut off with a relay or the 2 post moroso style? What makes one better than the other

 

Thats exactly how mines wired.
