'94 Yamaha 150txrs

I have a '94 Yamaha 150 txrs and need the wiring diagram for both the tach and speed/fuel gauge. Fuel and speedo not working. Fuel level flashies briefly when you turn the key then disappears? Any ideas? Please email them to bricekincaid@msn.com. Thanks in advance.

Test fuel tank sender and pink wire from sender is connected to white wire on speedo. Make sure tank sender has a good ground.
