Power

The fuse on the red power cable might have the wrong rating, open up the waterproof case, and check the rating. If the fuse has blown simply replace the fuse with a new 5 x 20 mm 12A fuse.

There may be issues with the fuses, breakers, or connections. Check each of these for any problems and replace them if needed to keep everything running smoothly.

If the fuse keeps blowing, take a moment to check for any cable damage, broken connector pins, or incorrect wiring. Addressing these issues can help prevent further problems.

There may be damage or corrosion on the cables or connectors, be sure to replace any cables or connectors that show signs of damage.

While the unit is turned on, gently flex the power cable to see if it causes the unit to reboot or lose power. If it does, replace the cable.

Check the vessel’s battery voltage and inspect the condition of the battery terminals and power supply cables. Ensure all connections are secure, clean, and free of corrosion. If you find any issues, replace parts as necessary to maintain reliable power.

Some components may not be performing at their best. While transmitting at 25W, use a multimeter to check for any significant voltage drops across all connectors. If you find any, replace the affected components to ensure everything functions smoothly.
