JRH Posted February 11, 2016 Share Posted February 11, 2016 I think there are 3 wires on the back of the gauge, brown + , Black/ yell - , and yellow/white to the float. Through the float to the (-)Link yel/white gauge read full. Disconnect link gauge read empty. Do not link wires for long.HTH.If you do not have a manual there are several on internet to down load.

iangaryprice Posted February 11, 2016 Share Posted February 11, 2016 Now you have a multimeter you can use it to check the wiring. Use the meter on the resistance range like you did to check the float.Good wiring will give resistance close to 0ohms. Also use it on voltage (use a range that is greater than 12v usually 20v).With the ignition on one of the terminals on the gauge should be 12v.

Phooey Posted February 12, 2016 Author Share Posted February 12, 2016 Got a feeling it's the sender unit. Took the float assembly back out and tested it in the sink. Floats no problem. Connected it all up and gauge read empty. Moved the float to other side and gauge read full. Held float in different places between empty and full and gauge read all over the place including empty when should be half full etc.Kawasaki want £120 Fleabay don't have any and I need the gauge ... can't be doing with all this guessing and trip business. Gauge was pretty accurate too. Quote Link to comment Share on other sites More sharing options...
JRH Posted February 12, 2016 Share Posted February 12, 2016 Right, the sender is a coil of wire on a former and this is connected to one of the wires. The floaty bit is a wiper that rub up and down the coil(quick nurse the screens). The other wire is connected to this wiper. So as the wiper moves up and down the resistance changes. It is possible that some muck or something has got Into that area and sat the wiper moves it is touching different areas. Hope that makes spence, it does in my head. So it may be possible to clean the wiped area of the coil and hopefully restore the operation. If if don't you haven't lost anything by trying. Unless any one else has ideas.

eastanglianbiker Posted February 12, 2016 Share Posted February 12, 2016 look for a tatty tank then might find one cheap with both tap and sender in it Quote Link to comment Share on other sites More sharing options...

Possibly an old tank for £30 swop out the sender and re-sell the tank to recover something back.http://www.ebay.co.uk/itm/172078042886? ... EBIDX%3AITFew option.
