Miniature Low Fuel Warning Light Module (for resistive senders)

This Low Fuel Warning Light Module is our own design.

• Works best with low resistance when empty senders
• It lights an LED when the fuel level falls to a set level
• it will work with both low resistance when empty and high resistance when empty senders

The Low Fuel Warning module has four connections, Power, Ground, Sensor, and LED.

Setting the switch point is by adjusting the 22 turn potentiometer with a small screwdriver.

full instructions are enclosed

• No case is provided as this module is designed to be mounted inside other equipment
• provided with double sided tape for mounting

The module has a deliberately slow response to changes in the input signal. This solves two problems found with simpler units

• when fuel sloshes around in the tank, the sender moves, but the light remains steady
• bimetallic panel regulators can pulse the supply to the sender, the indicator will ignore these fluctuations.

A  3mm water clear RED LED  is included with this module;

A 3mm mounting bezel is also included (although this may not be required)

• can be added to most vehicles with a resistive sender
• works in conjunction with a conventional gauge

When mounted inside a 52mm fuel gauge, no external connections are needed.

Made with surface mount components and multilayer ceramic capacitors for long life and stability

Maximum LED load 20mA

Note -  You do not need a low fuel sensor for this module to work
