Hello from Michigan. My problem is for someone that knows a little about motorcycle(scooter really) circuits, and a little electronics.

I've got a scooter that runs a standard 12V system, ~14V when running. My fuel sender provides a 1705ohm(empty), and 472ohm(full) signal.

My gas gauge runs either 510 or 100 ohms. I'm not sure what this means?

Is there a way to convert the signal to one that works with my new gauge? Voltage divider?

 

That means ur gauge wont be accurate or even close for that matter.
you have to check the power applied to the gas gauge by manually varying the resistance using a pot, so you can check the limits, only then you can implement the fuel sender.

 

Hello Estudent. Welcome to AAC.

Have a look at this project:

It's pretty similar to what you need to do. Just change the numbers to what yours are, and re-calculate.

If you don't understand it, please post back in this thread, not the project thread.

 

Yeah, this looks familiar from my Op Amps class. I've built the circuit before, but that was in class. Never for a real life project. I guess I failed to make the real world connection.

Thanks for the replies, I'm sure I'll post back with more questions.
