9. Troubleshooting and Support
Consult this chapter in case of unexpected behaviour or if you suspect a product fault.
The correct troubleshooting and support process is to first consult the common issues as described in this chapter.
Should this fail to resolve the issue, contact the point of purchase for technical support. If the point of purchase is unknown, refer
to the
Victron Energy Support webpage

9.1. Cabling issues
Cables heat up
This can be caused by a wiring or connection issue. Check the following:
• Check if all cable connections are tightened with a torque moment of 14Nm.
• Check if all fuse connections are tightened with a torque moment of 14Nm.
• Check if the surface area of the cable core is large enough for the current through that cable.
• Check if all cable lugs have been crimped correctly and are tight enough.
Other cabling issues
For additional information about issues that can arise from bad or incorrect cabling, cable connections or wiring of battery banks
refer to the

9.2. Fuse issues
.
Red fuse LED on
This is caused by a blown or a missing fuse. It can also be caused by a malfunctioning fuse or if the fuse connections are loose.
The Lynx Distributor measures the voltage over each fuse. As soon as it is more than 0.5V the fuse is marked as blown and if the
voltage is less than 0.3V it is marked as ok.
• In case of a blown or malfunction fuse – replace the fuse.
• In case of a missing fuse because the circuit is unused - place a dummy fuse in the unused fuse space.
• In case of a loose connection - check if both fuse connections have been tightened with a torque moment of 14Nm.
Red fuse LED intermittent on
This is most likely caused by a loose fuse or a bad fuse. Refer to previous paragraph.
Fuse is missing in the VictronConnect list
Check the fuse name with the VictronConnect App. When the fuse name field is empty, the fuse will be disabled from monitoring
and ignored.
Fuse blows as soon as a new fuse is installed
Check the DC circuit that is attached to the fuse for the following:
• Check if there is a short circuit.
• Check if there is a malfunctioning load.
• Check if the current in the circuit is not larger than the fuse rating.
Blown battery fuse not being detected straight away
When batteries are connected to multiple Lynx Distributor circuits and if one of the battery fuses blows, the fuse monitor will not
measure a high enough voltage over the fuse to trigger a broken fuse alarm, until the battery is being charged or discharged.
Blown battery fuse not being detected
The fuse monitors in Lynx Distributor modules with older firmware (pre HQ1909) cannot detect a blown fuse when batteries are
connected to multiple Lynx Distributor circuits.
9.3. Lynx Distributor operational issues
Does not power up (No LEDs)
The electronics that drive the fuse detection circuits and the Lynx Distributor receives its power from a Lynx Smart BMS or from a
Lynx VE.Can via the RJ10 cable. When correctly powered up, the power LED should illuminate either green yellow or red. If no
LEDs are illuminated at all check the following:
