Electrical Gremlins?
« on: December 09, 2015, 05:10:25 PM »
Recently I had one headlight not working.  Bulb was blown.
(yes its hard to replace with big hands)

Today I drove my TT SE in heavy rain. Last 2 miles under street lighting
All was ok.  Upon arrival at home I stopped, daughter off, me off to
open gate. Looked back at bike no headlight on just running light.
Engine is ticking over. Flicked to high beam, nothing.  Remembered
the dealer said last week when I lost throttle response, pull over
safely and switch off bike to reset, switch back on issue possibly
fixed.  SO, switched off.  Switched back on hit start, NOTHING.
Screen working, fuel priming, tail light and front running light
on, also instruments.  Switch off bike get help to push into my
garage, its up hill.  Go to the fuses.  Check every one.  The rear
fuse box position 1 20amp fuse is blown. It is Headlight fuse
Replace fuse, switch on bike started ok.  10 seconds later headlights
which had come on as they should go off.  Repeat switch off bike,
switch on no start. Now I have 2 fuses left.  Try one more, bike starts
lights working then off, fuse gone. 1 fuse left.  Its raining cats and dogs. 
The nearest garage for possible  fuse replenishment is 2 miles away, no
access to car.

What would YOU do.?

Regards.....

 Find the short.  I would think the headlight wiring is rubbing somewhere and have no insulation left and intermittently shorting out.

Hope its not a short John348,
I'll have another look at it tomorrow, maybe some magic wd40.

Beginning to loose confidence in it as an all weather bike

My last Triumph a 2008 Tiger 1050 had a problem that was like yours.
The turn signals quit working and once I shut the Tiger off it would not restart but if I did not shut it off it would keep running , the fuse was blown for the turn signals and once it blew the fuse for heated grips I did not have heated grips that was odd.
I had to replace the switch , if I did not use the turn signals it would run and restart with no problems.
The week before I had spent five days out of nine in heavy rain , if you have any dielectric grease I would pull the headlight switch apart and use that to try to see if the rain has shorted across the contacts.
Best of luck.

You can sometimes tell from the state of the fuse how it blew.  Clean break usually means sudden over current (short) or melted long term just over 20 amps current.

Does seem strange that the headlight blew and then this probably coincidence but is the new bulb taking too much current?  But 20amps is a lot (240 + watts) for headlights there again 2 100 watt bulbs with the extra light would probably be over.

Strange issues though

I'm guessing that your 2013 Trophy is now out of warranty ?

Even so it might be worth a call to your Dealer to see if they can help - just plugging it in
to their Diagnostics machine might identify the fault and save you Hours of investigation.

Depending on what t is, even if out of Warranty, ( by just a few months ? )
a call or Mail to Triumph After Sales / Customer Service might result
in a Goodwill contribution towards the repair cost ?

Yes coconut, out of warranty.

Is there any possibility that with headlights not working, the bike is designed NOT to start?
A sure test would be if someone pulled their headlights fuse and attempted a startup !

I definitely have a short on the lights issue, possibly infringing on startup electrics.  Bought a box of 20 amp fuses.  Too late now but first thing tomorrow I will have another look.  (floodwaters rising in my town, seriously) May check out the light switch cluster for water ingress.  Its a long recovery to take it to Dealer, 100km each way with no hope of a loan bike to go home if repairs are over one day.  Not sure I would attempt to ride it. 

Regards

I would think it very unlikely that it would be designed in to prevent the engine from starting
if the headlamp circuit is not functioning.

It is not illegal ( as such ) to ride during normal daylight without headlights,
but in these high tech electronic days, who knows ? !

Something I forgot to suggest previously is that you check to see if there are any DTC's
( Diagnostic Troubl Codes) stored on yoour Trophy.

Here's a link to instructions on how to display any DTC's on your Instrument Panel,
which also has a Word document atttached to explain the meaning of any codes that you have :
Servicing Data, Reference Info, and DTC ( Fault ) Codes
