1 pointThere's your problem right there..
1 pointIt's mounted to the front of the battery box into the footwell... It's a 3002 HD switch. Rated at 500a continuous, 700a for 5min, 1150a for 1min and 2750a for 5sec. I'm imagining things will melt/catch fire long before the switch gives up! I used a 92mm holesaw for the cutout. https://www.bluesea.com/products/category/11/35/Manual_Battery_Switches/HD-Series It was the highest continuous rated I could find at the time.
