This information is applicable to the following products:
- Entire REDARC Gauge range
The centre black circle on gauge is flashing intermittently - what does this indicate?
If the black centre circle is flashing and the gauge sounds an alarm, the gauge may have been programmed to trigger a relay, but a relay is not detected. Check the relay connection or reprogram as required. If no relay output is required refer to setup mode 12 and select ‘nc’.
Do I need to purchase the optional sensor for my gauge to work?
No, the standard features of the gauge will still work. To purchase the optional sensors please visit redarcelectronics.com/gauges.
What is the P-clip used for?
Attaching the P-clip to the back of the gauge ensures that the connectors are strongly fixed to the gauge, thereby minimising the risk that they may come loose or damaged during installation and/or rough driving conditions.
Is the gauge compatible with my existing vehicle sensors or other sensors available in the market?
The gauge has only been designed to work with the sensors supplied with / sold by REDARC.
What is the best mounting solution for my gauge?
REDARC offers a range of mounting panels and a mounting cup for its gauge range. Please ensure that fitment of your gauge does not impede on your driving field of view or create a head impact hazard. The available range can be viewed at redarcelectronics.com/gauges.
Should I enclose the wiring harnesses in conduit?
REDARC recommends enclosing the supplied wiring harnesses in a suitable conduit that will protect the wiring against sharp edges and/or extreme temperatures.
Where should I install the black push button?
In most cases, once the gauge is set up and programmed the push button can be hidden behind the vehicle's instrument dash panel. However, if you believe that you may need to regularly change any of the modes or wish to use the peak hold feature you should mount the push button in an accessible area (e.g. at the back of the mounting cup).
Can I fit my gauge to a 24V vehicle circuit?
The gauge requires 12V to operate. A 24V to 12V adaptor is available for purchase (i.e. P/N GA-2412V). This can be purchased for all gauges. Please note the G52-VA and G52-VWA will only allow you to monitor the voltage of 12V sources.
My gauge is too bright when driving at night.
You will need to purchase an Enhanced Lighting Controller (i.e. GA-ELC). This module is to be used:
- When you do not have a dimming circuit you can connect your gauges to.
- If you are using REDARC Gauges for all of your instrumentation so require dimming
or - The dimming circuit in your vehicle does not dim the REDARC gauges to your liking.
The GA-ELC allows you to program the night time brightness and colour of your gauges, including dimming if connected to a dash dimmer (i.e. once programmed your gauge(s) will change colour when turning on your park lights and back to a day light colour when you turn them off). You only require one ELC for a complete set of gauges. It can be used in conjunction with the 24 volt adaptor (GA-2412V) for a 24 volt system (ELC module is 24v capable).
Two gauges installed in vehicle and both showing maximum readings.
Secondary harnesses may be connected to the incorrect gauges (e.g. EGT/Boost harness to the PWT gauge and vice versa).
Can the Alarm sound be turned off when the alert level activates?
No – the Alarm will always sound when the alert level is reached. Except for the voltage gauges, the alert level can be changed so the gauge does not alert so frequently.
What is the accuracy of the readings on my gauge?
The accuracy of the readings is approximately +/- one chaplet. For example, this means that the VA gauge has an accuracy of ±330mV at 16V (or ±2%).
Other variants:
- G52-VA: 0.2 Volts per Chaplet
- G52-EB: 20 °C per Chaplet
- G52-EU: 20 °C per Chaplet
- G52-PT: 3 psi per Chaplet
- G52-TA: 3 °C per Chaplet
- G52-WA: 0.03 Volts per Chaplet
- G52-BE1: 2 psi per Chaplet, 25 °C per Chaplet
- G52-BE2: 2 psi per Chaplet, 25 °C per Chaplet
- G52-BEP: 2 psi per Chaplet, 25 °C per Chaplet
- G52-BET: 2 psi per Chaplet, 25 °C per Chaplet
- G52-POT: 4 psi per Chaplet, 5 °C per Chaplet
- G52-PWT: 4 psi per Chaplet, 5 °C per Chaplet
- G52-TTT: 5 °C per Chaplet, 5 °C per Chaplet
What is the 'peak hold' (PH) feature?
NOTE: This is not applicable for G52-VA & G52-VWA
When the gauge's push button is pressed, the needle pointer(s) and/or digital display will show the highest/peak reading recorded for the function being monitored. The peak measurement will reset when the vehicle's ignition is turned off.
What is the relay output rating?
NOTE: This is not applicable for G52-VA & G52-VWA
Positive output internally limited to 1.3A, however a 1A max load is recommended.
Will the gauge relay output wire activate/deactivate when the alert level is reached?
NOTE: This is not applicable for G52-VA & G52-VWA
Except for the voltage gauges, all gauges have the relay function. The relay function is triggered by the programmed alert level upon installation. It will activate/deactivate when the programmed level is reached.
