Fuel Management - Starcom Systems Helios Installationsanleitung

Fuel Management

The fuel tank in passenger vehicles it is generally located under the passenger back
seats. Typically, it has three or four wires, as follows:

Fuel Pump – When the engine is running, you can measure 12V on this wire.

Ground.

Fuel Gauge – Analog wire. When the engine is running, you can measure 0 – 8V
depending on the fuel level. This voltage may vary between different vehicles and
requires calibration.

Fuel Warning LED – Digital wire. Not present in all vehicles. When the fuel level
falls below a critical level, this wire lights a warning lamp on the dash board.
Connecting your testing lamp to this wire also causes the warning lamp on the
dash board to light.
Gas Tank Level
To connect the gas tank level pin:
1. Identify the fuel gauge wire analog wire. To verify that you have found the correct
wire, turn off the main electrical switch and cut the wire. If this is the fuel gauge
wire, the fuel gauge on the dash board will show a maximum fuel level.
2. Connect the fuel gauge wire to the Gas Tank Level pin (#11) – Analog 1 Input.
Warning: Do not connect a negative voltage to the fuel pump as this
may cause damage.
