It seems like you are experiencing an issue with the fuse for your temperature gauge and revolution counter (RPM). When a fuse keeps blowing continuously, it indicates that there is an underlying problem causing a short circuit or an overload in the electrical system.

Here are some common reasons why a fuse for these components may keep blowing:

1. **Short circuit**: This is when a wire or component in the circuit comes in contact with a ground or metal surface, causing a surge in electricity flow.

2. **Overload**: If the electrical components connected to the circuit draw more current than the fuse is designed to handle, it can cause the fuse to blow.

3. **Faulty components**: A faulty temperature gauge or revolution counter could be drawing too much current, causing the fuse to blow.

To diagnose and fix the issue, you can try the following steps:

1. **Inspect the wiring**: Check for any exposed wires, damaged insulation, or loose connections that may be causing a short circuit.

2. **Disconnect components**: Try disconnecting the temperature gauge and revolution counter to see if the fuse still blows. If the fuse holds, the issue may be with one of these components.

3. **Check the ground**: Ensure that the components are properly grounded to prevent any stray currents.

4. **Replace the fuse**: Use the correct rated fuse for your car's electrical system to avoid any potential damage.

If you are unable to identify or fix the issue yourself, it would be best to seek help from a professional mechanic to prevent any further damage to the electrical system of your car.
