Why has my JControl screen turned off?

The JControl receives power to run the monitor from the J35. If the J35 shuts power to the monitor, the JControl screen will turn off.

The J35 will shut power to the JControl if:

1. The load isolation switch connected to the J35 has been activated. This turns off power to all caravan loads and accessories connected to the J35 CAN bus, such as the JControl.
   Check that the switch has not been activated.
2. Battery voltage is very low. The J35 will enter Storage Mode to conserve remaining battery voltage, which will disable power to all caravan loads and accessories connected to the J35 CAN bus.
   Connect the J35 to a power source and begin battery charging. When the battery is sufficiently charged, the J35 will enable power to the JControl.
