Weird Turn Signal failure - 1150 GS Adv

Just collected my 2003 1150 Adv from Scrimingers after having a custom geartbox fitted. Unfortunately by trailer - hey ho...

Got back to my mate Peter's garage and decided to fit the HIDs and Autoswitch I'd bought. Bike on ramp, tank off, headlights off. Decided to sort the autoswitch first, so disconnected the right hand handlebar switch main plug under the tank, before baring a section of the Brown/White wire on the 'bike' end of the connector. This is the 'Turn Signal Cancel' wire and should give a pulse to earth when the indicator cancel button is pressed.

Reconnected the plug and put the multimeter on the positive battery terminal and the bared wire, turned the ignition on - no reading. Pushed the cancel button - once again no reading. Hmmm. Tried the Turn Signals - they didn't work. Checked that the plug was correctly seated and all pins in good condition. Neither indicator worked.

Weirdly, though, the hazard lights worked as advertised from the switch, both on and off.

Work I have done affecting the Turn Signals recently:

Fitted rear LED Turn Signals with extra brake lamp LEDs - these worked as advertised after fitting and the brake light LEDs still work - as do the Turn Signals, but ony as hazards.

Fitted front LED Turn Signal and these also worked as advertised (and still do - but only as hazard lights).

I rode the bike 70ish miles to Sleaford last Saturday when all the Turn Signals were working OK. Steve Scriminger replaced the gearbox, the header studs in the heads, changed the final drive oil, fitted a new clutch slave cylinder and air filter. He also did a throttle body balance. None of this would, on the face of it, have any effect on the problem - I mention it for completeness.

I have a spare Turn Signal relay in the garage somewhere, so I'll be replacing that as a logical next step, but I'm pretty sure the same relay controls the hazard lights, so I'm not hopeful that this is the cause.

Any ideas?

Mike

Not a fused circuit.

All the fuses are intact though...

Did you try it without the Autoswitch?

All of this happened without fitting the Autoswitch - the wiring was normal except for the section of insulation removed from the Brown/White wire. I can't say for certain that the turn signals worked before we'd bared that wire (and which we kept protected - ie didn't let it ground or anything), by have no reason to think that was a factor...

Unlikely the mechanic caused the failure. He didn't mess with the electrical system, but you did; and the turn signals specifically. It's a good chance your LEDs have something to do with it. Start reversing everything you've done, check operation at each step.

I've got a Y2K 1150GS, when I installed my LED turn signals I got a "fast flash" when I turned them on, but the hazards worked normally. This is because the flashing is controlled by the motronic. You may find the problem lies therein.

I hope this helps, somehow.

Cheers!

Sir,

My hunch would be the turn signal cancel wire. If that wire is somehow connected all the time (=cancel switch is pressed), then the flasher relay can't work. The alarm flashing has its own on/off switch, ie is not influenced by the cancel switch.

This seems to make the most sense. The cancel switch has no effect on hazard lights (which you state are working). So if we take it to be true that the cancel switch grounds the flashers, then you have a grounding issue with the circuit.

I'd agree, but the circuit isn't connected to earth/ground when tested, whether the switch is operated or not...

Could there be a short to ground on the circuit that you aren't aware of? My apologies that I'm not familiar with the circuit in question, but am familiar with circuits in general.

Update:

I've now got the bike in the garage. When I disconnect the RH switchgear at the under-tank multi-pin plug, the left indicator now functions as normal.

It's tempting to point the finger at the right hand switchgear, but I guess the fault could also be anywhere where the circuits are 'made' when the switchgear is connected?

Please don't apologise - I need all the help I can get!

Please see my latest update above...

Does the right side work when you disconnect the left?

I'm still thinking there's a short and it seems the right side is culprit. I think if the answer to the question is false, I would focus on right-side.

Replacement switchgear fitted and problem cured.

I've got some spare switches in a drawer somewhere, so I'm going to remove the switchgear at the weekend and replace the turn signal cancel switch.

Many thanks for all the help...

Mike
