IF something doesn't light up

• Check power wires connected to the device

IF Krakens flash red

• Check all of the CAN wire connections
• Make sure to put and check the resistor on the end of the CAN bus

IF none of that works

• Check all of the components one-by-one
• You will know the problematic area 
• Try to replace the wires (might be burned or cut)
• Replace the resistor to check if it works
