Dash warning lights

[DaveB916]

Hi,

My 1150GS has started to do some unusual things with the warning lights.

The oil light does not come on, the neutral light brings on the battery light both dimly and I only have one flashing abs light, should I have 2 ?

I think the petrol warning lamp is ok, and so are the indicator warning lamps.

I have checked all the bulbs, all are fine.

I suspect these are all common earthed lamps and the earth is suspect, but where is the earth actually located, anyone know, save me chasing wires round and round ?

Thanks in advance for any help.

It does indeed sound like one of the earth junctions.

Remove the tank and find the loom section that runs up the right hand side of the headstock to the clocks. Split the covering sleeve and have a look inside. There are a few earth junctions in there which are prone to corrosion as that section of the loom fills with water - you'll probably find a broken wire(s) and / or green fur.

Remove the tank.

You will see a "mini-loom" which runs from the connector blocks under the tank, along the offside of the headstock and up to the instruments.

Carefully cut the outer sheath of this "mini-loom" and you should find at least a couple of corroded or broken earth wire connections in there.

Solder and heatshrink any broken connections and you should be good to go again.

You're fast on the draw today Matt.

Just happened to be looking at the right time

Thanks chaps.

Being a newbie to Gs's, does the tank simply lift off and fuel lines have some form of connection on them ?

I have had a quick look and can see connections on the overflows but not fuel lines.

A manual will be useful for this, but basically:

There are two high pressure fuel lines, a breather, the filler neck drain and an electrical connector block.

Remove the seats and the black side panel below the right hand side of the tank.

The fuel lines are the fat hoses which join onto the hard plastic lines by the right hand throttle body. If you don't have quick releases, you'll have to clamp the rubber lines off , separate them from the hard plastic lines and plug them (unless you want to de-pressurise the fuel system which is a pain in the bum). An M8 screw fits nicely into the rubber line and you can use the original hose clamp to hold the screw into the line. Put a washer on one of the M8 screws to remind you which is which (they aren't interchangeable).

The thin breather and filler neck drain can just be parted at the plastic connectors by the frame rail.

Undo the screw which holds the back of the tank down (rear right), lift the tank up about 6" or so (prop it with a piece of wood or something), locate and disconnect the electrical connector, then pull the tank backwards and up to remove it. Have somewhere ready to put it down when you've got it off.

Before any of this, syphon as much fuel out of it as you can as it's bloody heavy when full

The gubbins looks like this (my plastic 1100 tank but yours will be the same):

You could also check the connections to the back of your fuse board... Fuse 1 ( the one nearest to the sidestand side of the bike) played up with me... all sorts of wierd combinations ...

Brake light worked the ign light, one abs light, neutral stayed on dimly.....

Just shoved the connector in better from the back and all was well

Thanks guys, I have just ordered some quick disconnect jobbies, I'll have a look at this later in the week. Thought my bloody Ducati was a pain with electrics .......... lolol

Must say tho' had a ride out yesterday and was quite impressed, pulls really hard and handles quite well.

Might risk a lap of Nurburg on it later in the year.

Ideal opportunity to fit QD's

If you're going to fit QD's, make sure you're getting the ones that self seal on both halves when split (not all do) and fit them in different directions on the high pressure lines so you can't mix them up when reconnecting.

 

[DaveB916]

Nice tip, yes ordered the 'bi-directional' sealing type.

Was wondering how to mark the pipes, but like your idea better.

Thats the way to go, get a couple of spare O rings as well just in case ne day you undo them and they don't seal to well happens, so be prepared.

Well, removed tank and headlight and a rumage around with a meter. All earths appear to be present and correct but no supplies to neutral, oil warning, charging and lower ABS lights.

Managed to borrow a Haynes manual and have a root through the wiring diagrams, appears these are all commonly fed by a green wire from fuse 1. So will now have to go chasing that one, seem to remember it was present on the fuse side of the multiplug under the tank, right hand side.

The plug was a pig to split and had some corrosion in there, so will give it a good clean and chase it forward of that.

Problem solved.

There is a green/brown wire that feeds all the lights, this wire is a single wire from the plug that then splits into 2 wires and then 4 wires o feed the warning lights.

This is a horrible crimp joint that has obviously corroded, some time and a soldering iron and now I have a dash like Blackpool illuminations.

I am now confident there is oil pressure .........lol..........and the battery is charging, and a neutral light to boot !
