Power up troubleshooting

Blown fuse / tripped breaker:

1. Check condition of relevant fuses and breakers and connections, replace if necessary. (Refer to the Power Connections section of your product’s Installation Instructions for fuse ratings.)

2. If fuse keeps blowing, check for cable damage, broken connector pins, or incorrect wiring.

Poor / damaged / insecure power supply cable / connections:

1. Check that the power cable connector is correctly orientated and fully inserted into the product’s Power connector, and locked in position.

2. Check the power supply cable and connectors for signs of damage or corrosion, and replace if necessary.

3. With the product switched on, try carefully flexing the power cable near to the product’s Power connector to see if this causes the unit to restart or lose power. Replace if necessary.

4. Check the vessel’s battery voltage and the condition of the battery terminals and power supply cables, ensuring connections are secure, clean and free from corrosion. Replace if necessary.

5. With the product under load, using a multi-meter, check for high voltage drop across all connectors / fuses etc, and replace if necessary.

Incorrect power connection:

The vessel’s power supply may be wired incorrectly. Ensure that the product’s Installation Instructions have been followed completely.

Power supply and connection:

See possible solutions from the table above, entitled ‘Product does not power up, or keeps switching off’.

Software corruption:

1. In the unlikely event that the product’s software has become corrupted, try downloading and installing the latest software from: www.bit.ly/rym-software

2. If your product includes a display: as a last resort, attempt to perform a ‘Power on Reset’. Be aware that this will delete all settings / presets and user data, and revert the unit back to factory default settings.
