Why does my Stack ST8100 speed reading stop working after a short time?

  If your Stack Monitor speed reading dies after a short time, the ambient temperature might be too high. Shield the sensor from radiated heat from brakes and bearings. Insulate the sensor from conducted heat with fibre washers, and duct cooling air around the sensor.

  Christopher ClarkAug 25, 2025
  If your Stack Monitor displays pressure values that are too low and temperature values that are too high, the cause might be low battery voltage. Try recharging the battery to resolve this issue.

  If your Stack Monitor display is dead, showing no backlight or any activity on the display, but the green dial lights are dimly lit, or if you see a !! LOW BATT !! warning, it indicates that the battery is almost dead. Recharge or replace the battery. Also, check the power connections to B- and B+ to ensure the power lead has continuity.

  If your Stack Monitor displays a fixed temperature reading of 999° C or 999° F, it is likely that the temperature sensor has failed and needs replacement. Another potential cause is faulty sensor connections, so check the continuity of the sensor leads.

Why are there no alarms for water, oil, or fuel on my Stack ST8100 Monitor?

  David RobertsSep 18, 2025
  If there are no alarms for water, oil, or fuel temperatures and pressures being displayed on your Stack Monitor, all the alarms may have been switched off; switch on the required alarms. Alternatively, the engine RPM gate value may be set too high; reset the RPM gate to a lower value.

Why are all sensors on my Stack ST8100 Monitor showing fixed high values?
- S
  Stacey HahnSep 3, 2025
  If all sensors on your Stack Monitor display fixed high values, the Switch 1 (Peaks) might be faulty and needs replacement. Also, check the switch wiring, as faulty wiring could be the cause.

Why does my Stack ST8100 Monitor show a constant pressure reading of 0 PSI?
- L
  Lauren MorrisSep 1, 2025
  If your Stack Monitor displays a fixed pressure reading of 0 PSI or 0.0 Bar, or you suspect a low/slow reading, the pressure sensor may have failed and needs to be replaced. Also, check the pressure connections, as faulty sensor connections could be the cause.
