Fuel Gauge Check

1. Remove the power supply tightening screw.
2. Use an ohmmeter to measure the resistance value between the terminals.

CAUTION: When Inserting the testing probe into the power supply terminal, be careful not to touch the printed board.

Standard value:
Power supply - Ground 249 +/- 30 ohms
Power supply - Fuel gauge 127 +/- 25 ohms
Fuel gauge - Ground 122 +/- 10 ohms

3. If within the standard value, the fuel gauge is OK. If not within the standard value, replace the fuel gauge.
