🔌 Function

The gauge converts resistance from the tank sender into an EMPTY-to-FULL indication. Accurate operation depends on sender resistance, float movement, stable power and a clean tank ground.

⚠️ Common Signs of Failure

• Gauge remains permanently on EMPTY or FULL
• Reading changes because the sender float binds
• Corroded sender wiring causes an intermittent reading
• Incorrect sender resistance produces false fuel levels
• Backlighting or internal gauge movement fails
