System Startup

The Bolt control system will perform a self-test on power up. 

During the self-test, the system will check for the presence of a 

working Bolt Actuator connected to both the Port and Starboard 

outputs of the relay module.  If the system does not detect an 

actuator, the upper yellow LED will flash on the side that the error 

was detected.

If either of the upper yellow LEDs is flashing, try to move the 

actuator using the control to confirm that there is a problem. 

Check the electrical connections at the actuator and at the relay 

module if an extension cable is used. Verify that the plug and 

receptacle at each connection is properly seated.

Turn off power to the system and then repower to cause the 

system to go back through a self-test on power up. If the problem 

remains, switch the port and starboard output cables at the relay 

module.  Power the system down and then repower to again cause 

the system to go through a self-test.  If the problem switches sides 

and the opposite Yellow LED is now flashing on the BCI Display, 

then the problem is with the actuators. Disconnect the actuator 

and inspect the wire terminals. If one of the contacts has been 

pushed back in the connector, remove the wedge lock and push 

the connector forward until it clicks. Re-install the wedge lock 

and retest.  For help with connectors visit BennettTrimTabs.com/

. Repeat this process for the connection at the relay 

module if an extension cable is used. 

If the unit continues to fail after checking the connections and the 

unit consistently fails on both Port and Starboard connections, 

then the problem is likely with the actuator.  If the failure remains 

with the same LED on the same side (Port or Starboard) after the 

actuator connections are changed, then the failure is likely with 

the relay module. Contact Bennett Marine Technical Support for
