Visible Symptoms of a Chevrolet C3500 Fuel Gauge Gone Bad
For most owners, the fuel gauge in the dashboard is a very important tool in taking care of their automobiles. This mechanism provides accurate information on the fuel level inside the fuel tank. It lets you know if you need to drive to a gas station and fill up your tank. Your fuel gauge is composed of two main parts: the sender unit and the actual fuel gauge. These two parts are known for showing signs when there is a defective dashboard voltage regulator, loss of ground, and bad wiring connections. With this, you need to be aware of these signs to better take care of your fuel gauge.
Your fuel gauge may hang up in one position before returning to normal function. This is caused by the sender unit's float in the fuel tank. This is a mechanical issue as the float sticks to a particular spot inside the fuel tank. A hung up fuel gauge may return to its normal position once the vehicle drives through a bump. However, the float may stick to a same point again after the tank is filled up.
When the needle of your Chevrolet C3500 fuel gauge is restless while indicating an empty fuel, it is a sign that your sender unit is experiencing total failure. This is caused by bad electrical connections. When you experience this issue, you should check the fuse or wires connecting your sender unit to your fuel gauge. You may also check the voltage regulator that controls the electric current inside your dashboard.
Fuel gauge at constant full
If your fuel gauge shows that your fuel tank is full even though it is empty, there may be a short circuit somewhere along the connections. Your sender unit and your fuel gauge work with electrical signals. Once the electrical signals are disrupted, there would be issues with the display of your fuel gauge. The short circuit may occur on either your sender unit and your fuel gauge, so you need to inspect further before taking necessary actions.
Fuel gauge moving up
A common issue with your Chevrolet C3500 fuel gauge is when its display increases even though you are not filling up your tank. This is an early sign that your fuel gauge resistor is already worn out. With this, you should replace your resistor as soon as possible.
