I have a circuit for a motorcycle fuel gauge that needs adjusting. The fuel sender in the gas tank varies from 250 down to 35 ohms, depending on the fuel level. The gauge only reads resistance from 5 ohms to 100 ohms. I need to connect something that will change the resistance coming from the tank to match the specifications for the gauge input. Example...when empty of fuel, the tank resistance is 250 ohms...it should be 100 ohms. When it is full, the tank resistance is 35 ohms, should be 10 ohms. Can you help me with this? Thanks so much.
