Sure, the flashing trouble light on your SDi Bedrock BTB65 indicates that there’s a problem with the system. To troubleshoot this, first, check the user manual for specific trouble code meanings. Typically, common issues include low battery voltage, communication faults, or device malfunctions. Start by checking the battery voltage and ensuring it’s within the acceptable range. Next, inspect the wiring and connections for any signs of damage or looseness. If the issue persists, try resetting the system by power cycling it. If none of these steps resolve the problem, it might be necessary to contact a certified technician for further diagnosis and repair.
