New to 2010 Sh150i

[tmtran73]

Hello everyone, I am new to this forum and have no mechanical experience so please bare with me.

I just bought a 2010 sh150i with only 100 miles. It has two issues; fuel tank and fuel gauge.

Replaced the fuel with a used one which is in good condition. The old one was dirty (a lot of dust like clay) and rusty. clean the pump, pump housing and the floater. put it back together and filled it with gas in full. The gauge is still not working.

does anyone has the schematic (wire diagram) and pictures to troubleshoot the fuel gauge?

Here is a little to start with (from the Service Manual).......

"Disconnect the fuel pump 5P connector.
Check for continuity between the Green/black (ground) wire terminal of the wire harness side 5P connector and ground.
There should be continuity.

Remove the front handlebar cover.
Check the Gray/black and yellow/white wires for continuity between the fuel gauge and level sensor.
There should be continuity.

If wires are normal, check the fuel level sensor:
Remove the fuel pump assembly.
Measure the resistance between the connector terminals.
Green/black + Yellow/white = 25 - 45 ohms (float position UP) 400 - 700 ohms (down)
Yellow/white + Gray/black = 450 - 750 ohms.

I hope this helps to get you started and good Luck.......

does anyone have instruction how to remove the handle cover to check the gauge level?

Do i need to remove the pump assembly from fuel tank or just leave it in there to do the check at the connector?

To remove the handlebar cover:
remove the mirrors. Caution: the mirrors and adapters are not 'threaded' the same on both sides. The adapter on the right side is 'reverse' threaded.
remove the two socket bolts (the two large screws on either side of the instrument panel) and remove the 'garishes' by releasing their tabs and snap fit clips from the front handlebar cover.
Remove the 4 screws from the front of the handlebar cover.
Disconnect the headlight connector to remove the front handlebar cover....

You do not have remove the fuel pump in order to make resistance measurements at the connector.

I highly recommend that you obtain a factory service manual.
The instructions above are only a small portion of the information and explicit photographs/diagrams that are available in the manual.
Some things are difficult to put into words without a pictorial diagram.

Good Luck.
