Situation Possible causes and solutions
Missing, unstable or
inaccurate current/voltage
readings.
1. Loose connection to the monitored battery. Check
the connections, apply contact cleaner spray where necessary.
2. Improper wiring.
Double check all connections to the battery,
in particular, for having a common ground wire connected to the Device’s
black wire (see VI.1).
3. Too long or thin cables. Inaccurate readings may occur because
of excessive voltage drop in cables. Make sure to use appropriate wire
gauge (see Figure 1 in section VI.1).
4. Wrong shunt settings. Check and correct your shunt settings.
Negative current values are
displayed upon charging
the battery, positive upon
discharging.
1. Improper wiring to the shunt. Double check all connections
to the shunt.
No current/voltage data
on the chartplotter
1. Incompatible chartplotter. Your chartplotter does not support
PGN 127506 nor PGN 127508. Check your MFD manufacturer’s website
for a firmware update.
Missing, unstable or
inaccurate temperature
readings.
1. Battery temperature measuring device fails to supply data.
The device may go offline, or malfunction. Check its NMEA 2000
connection, and refer to its User Manual if necessary.
No temperature data on a
chartplotter
1. Incompatible chartplotter. Your MFD does not support displaying
battery temperature. As a workaround, you can set data type supported
by MFD in the settings of your temperature sensor.
