2003 Suzuki VS800GL playing up

[Aluria2009]

Turn on ignition and headlight is very dull , no speedo light even though bulbs are not blown , and both back indicators light up , engine starts , horn , indicators , tail light all go , at a loss to what it could be , all fuses have been checked , all earth connections checked as well . Any advice would be greatly appreciated with thanks .

Hi Aluria
Have you changed the Bulb? and checked all the wiring connections for wear and corrosion etc ?
It could just be a poor contact or corrosion build up causing excessive resistance, or even a worn/crushed cable etc.
Best to use a volt meter to see what volts/current is actually reaching these systems.

Bloody hate chasing electrical faults lol....aways a mission! :facepalm:

[Aluria2009]

Checked all wires and bulb isn,t blown , it comes on very dim also on high beam its dull as well , if you do not start the bike and turn on the indicator switch , then the indicators will not blink , but if you start the bike and do the same then indicators blink and work fine , all bulbs within the whole bike are fine with none blown and no corrossion can be seen anywhere . you turn on ignition and all 4 indicators light up only the front ones should as they are double filament and back ones are single .

Best put that batterie on charge over night to eliminate that as a possible cause, and check it with a Volt meter to ensure it is supplying the right amount of juice is being supplied (could have a bad batterie!)
Other than that mate.....best of luck! :facepalm:....bloody sparky bits are the bain of most us lol

[Aluria2009]

Had Temp sensor replaced last month as well as new battery , running great until weekend , when fault showed , may have to take to motorcycle shop and get them to look at it .

[Aluria2009]

If I take out the headlight bulb everything returns to normal and speedo light comes back on , once bulb is replaced in socket everything goes haywire again .

[Katman]

Try another bulb.

[Aluria2009]

and still the same problem the xxxxxxxxx but as soon as bulb is removed everything is perfect .

[Katman]

Does the connector that plugs onto the bulb look ok?

No sign of heat or melting?

[Aluria2009]

as soon as bulb is placed into socket then everything goes stupid , and even the 2 front indicators change from one filament to the front filament and back indicators light up as well , and speedo light and high beam light go off , take bulb out and it all goes back to normal .

[DR650gary]

Sounds like another Taniwha :shutup:

Follow the wires to your headlight back as far as you can. Possibly a short to the frame from a positive lead.

[Katman]

As above.....

And pay particular attention to where the wires go through the rubber grommet into the headlight housing.

[Aluria2009]

Have noticed if I take the headlight bulb out and turn on indicators all 4 indicators flash and so does the high beam indicator and speedo light as well , if I place the bulb back in all this stops and back indicators stay illuminated , speedo and high beam light go out and headlight is like a flat torch on both beams .

Hmmm dosn't sound good mate (Bloody Odd to be quite honest), could be fused wires some where or an earthing issue.

Checked the net and could only find a VS800 92 wiring diagram...hope it helps
Will keep looking tho as theres nothing worse than chasing the demon electrical fault ay

[Aluria2009]

There goes both my arms LOL will be interesting to find out what the cause is

[Guided_monkey]

You'll need a multimeter and some luck.

Dis-connect plugs and check for a 'dead' short to earth.

Hopefully you won't find what I have in the past.... GN250 that melted all the wires in the headlight shroud. I suspected that the 'qualified' workshop put a bulb of too high rating and it melted the headlight wires and all wires adjacent.
