Green live wire to one side of the gauge

There is a voltage stabiliser on the 885, I can't remember the colour of the wire between it and the gauge

The wire from the sender is green with a black trace

If it's a top mounted sender it's available as a replacement, if it's side mounted it's not available

That particular smiths gauge was only used on the non Q cab 885

Fuel gauge

Post by acs2703 » Mon Dec 28, 2015 7:17 pm

I have an 885 and when I bought it the fuel gauge just read full the whole time and after running dry one time and having a terrible time getting the resultant air lock out of the system I decided to fix the problem. In my case it was the sender unit that was broken. There isn't really much damping on the float arm on the sender and so the constant movement of the float arm means that the arm wiper blade just wears out the wires on the sender unit.

It turns out that open circuit between the feed and the gauge results in the gauge just going to full the whole time. It's quite easy to get the gauge, sender and battery all on a bench and just wire 12V to the input of the gauge, then the output of the gauge to one side of the sender, and then earth the sender body.

If you then move the float arm up and down the gauge should move accordingly. If not then chances are the sender is faulty - you should be able to see any break in the sender windings.

The ownder's manual (from the club shop) is great and has full wiring diagrams. The wiring should be Green/Black from the voltage stabiliser supply to the gauge, then another green /black to the tab on the centre of the gauge. The earth is simply through the body of the tank/sender.

I replaced my sender and it now works great - although a top mounted sender for the 885 is really hard to find.

I had exactly the same problem with my sender. I put a new top mounted sender in the tank of my 885, and within about a week it had worn through the resistance wires at the base of the sender unit. I have been racking my brain to try to find a way to dampen the float from sloshing up and down so much, but so far have not found a solution. If anyone knows of a way to fix this please let me know.
As far as bleeding my tractor after it has run out of fuel. I have never had much of a problem getting it started again. I just use the manual pump until fuel has reached the injector pump then crack an injector hose at the injector until fuel comes through while cranking the engine,and away she goes. I feel like I am lucky I have got an easy one.

There is a couple of things you can do to reduce the movement of the float. Keep the tank as full as possible and slow down on rough ground.
