I do, but since I have no idea what you have, I ain't gonna explain them all.
If you want to ask lots of questions, why don't you just put your type of engine, and drive along with SN and model numbers in your signature. Then we wouldn't have to ask.
Head up to the Adults only sticky at the top of this forum. Download the service manual for your drive. #6 is the one you want. It has all the info you need to troubleshoot and replace if needed.
Those senders go bad all the time.
Anyone know how to test these? Seems like the limit switch would be an on-off microswitch and the sender would be a potentiometer (variable resistor).
Any info is appreciated.
