next issue....fuel gauge not working...ugh

boatman37

So to pump my tank out I pulled the sending unit. There are 2 wires attached to it. After pulling it the fuel gauge is now not working. It is reading about 1/4" below E. The tank is about 90% full. The sender was installed at the correct orientation. It's a Crownline but I would think the system would be similar. Any ideas? Can't find any fuses anywhere on the boat. I checked the voltage between the 2 wires with the key on and got 9.7 volts so seems like there is power at the sending unit unless I should be checking ohms?

Could it be possible the float mechanism got flipped around and it is actually upside down inside the tank?

It never ends, sorry. Check ohms. Also make sure the ground is complete with ohm meter

Yeah. This problem was caused by us pulling the sending unit to have access to siphon bad gas out.

I figure I'll have to get a long wire to run to the engine for a ground and check the ground at the sending unit. If it's good then likely the sender wire?

Is your tank aluminum? That will be grounded.

boatman37

no. plastic tank
