i shorted out my fuel gauge on my harley davidson

⚠️ Fuel Gauge Shorted Out – What to Check

1. Check the Fuse

• Start with the fuse box — most Harley-Davidsons have a fuse labeled “Instruments” or “Gauges.”
• If it’s blown, replace it with the same amp rating (usually 15A or 20A).

2. Inspect the Wiring

• Look for melted, frayed, or exposed wires around the fuel gauge, tank, and connector plugs.
• Common short point: where wires pass under the tank or near the gauge housing.

3. Check the Fuel Sending Unit

• If the short reached the fuel sending unit (inside the tank), it might have been damaged.
• Use a multimeter to test its resistance — it should change when the float moves.

4. Test the Fuel Gauge

• With ignition on, disconnect the sender wire and ground it.
• If the gauge moves to full, it's likely fine and the sender is the issue.
• If not, the gauge may be fried and needs replacing.

5. Replace Faulty Parts

• Blown fuse only? Easy fix.
• Damaged gauge or sender? Replace with OEM or aftermarket unit.
• Reconnect everything properly — no pinched wires or bare terminals!

⚠️ Tip: Add a fuse inline if one wasn’t protecting the circuit before — it’ll save you next time.
