Operation modes
The ThunderBox can operate in three different modes. Depending of the connection of the
WHITE control wire the following modes can be acquired:
› Automatic mode:
The White control wire is left disconnected/unused.
When the engine is started and runs evenly, the TB switches the power outputs ON.
When the engine is stopped, after a few seconds the TB switches the outputs OFF.
› Ignition-controlled mode:
The White control wire must be connected to an ignition key sw12V power source,
e.g. to the hot wire of the number plate light.
The TB will switch the outputs ON/OFF (with a few seconds delay) following the ignition
key switch position.
› Stay-off mode:
The White control wire must be connected to the TB’s Black wire terminal block.
The TB will not turn the outputs ON even when a battery charger is connected. This is
useful during winter storage as a trickle charger won’t activate the TB.

Power management
› Delayed ON
When the power-up conditions are met, the TB delays power output for about two seconds.
Indicated with a rapidly flashing green light.
› Delayed OFF
When the ignition key is turned off, the TB turns the outputs OFF after about five seconds.
Indicated with the green light blinking slowly.
› Overload management
The intelligent overload management allows inductive loads such as halogen bulbs to be
lit/turned on. The TB allows overloading its circuit(s) for 200 milliseconds.
If the overload (greater than 16A) duration exceeds 200 milliseconds, the TB will turn the
power output OFF.
The TB attempts to restore power to the output three times. If the overload persists, that
circuit will remain switched-off/disabled until the TB has been reset by disconnecting the
