Hey, My indicators started going dodgy, like would work sometimes and sometimes wouldn’t, then if I cut out the engine and restarted they would work. now they don’t work at all, except… I have the shitty annoying triumph alarm and when I click it on or off all four indicators will either blink once if on or two if off so they seem to be working perfect in that aspect. It’s 2009 bike with LED indicators and ‘triumph flasher unit’ instead of normal relay. Fitted them about 3-4 years ago and not had any issues until now. Seen this flasher plug play units for £15 ish on eBay, thought about picking one of them up and trying it. any ideas? Anyone else had this?
@MartinDaytona Do you have a tail tidy fitted or other changes to the wiring? I gave a friend a hand with his a couple of years back whereby sometimes all or one side stopped working. We found exposed connectors with corrosion. Once repaired....all good as new. Hope that's your issue. Very easy fix if it is. Most likely to be the rears as the cables are more exposed
Hi mate thanks! Do you think if I take out all of the connectors from the rear LED and clean it all it might fix ? Interesting
It was corrosion in the connector to the rear LHS indicator that caused his issue. The circuit is simple so easy to trouble shoot but you might we'll find one or more crusty connector. Interestingly, his all worked when the alarm was activated also! Hope you get sorted. Intermittent problems are often the worst.
Imho that sounds like a good call from SW73 MartinDaytona, the back wheel chucks a lot of detritus along with the water at the tail-tidy, so if the connections from the indicators to the loom isn't exceptionally well protected they are going to be liable to corrosion. Your symptoms do sound rather like the sort of intermittent faults that would result.
Thanks! I’ll take a look today and clean it all up. Hopefully will sort it just by saying the circuit is easy to troubleshoot, do I have to look at actual wiring? Not just the connectors to the indicators where i unplugged the standard and plugged in the led? I didn’t fit the tail tidy so no idea how it was before, I did fit the leds though
I meant it's a straightforward circuit, compared to some. The Haynes manual or the workshop manual has a wiring diagram. I'd start though just by cleaning all the connectors. Good luck
All cleaned up and no fix I don’t understand because they flash for the alarm haha such a blag. Might buy one of them relays and see if they fixes it and if not send it back haha I have no idea what else to do. I cleaned all four indicators. I unplugged them all and plugged them in one by one to see if any one would on their own and that didn’t work. None would light up using the turn signal, but again would with the alarm. I guess if no luck with the relay I might have to take it in
Flasher unit is probably favourite, if they all work from the alarm which won't use the flasher "relay", it'll drive them directly. The connectors in the picture probably look worse than they are, triumph seem to use very sticky "grease" and that picks up any dirt on the outside, the contact pins could still be relatively clean.
I wonder if it could be the handlebar switch itself then (or the sub-harness that feeds it, and is therefore subject to the movement as bars are moved). I'm thinking that, if the lights themselves work from a source that is not the handlebar switch ( i.e. the alarm) then it seems a possible candidate. There have been reports (a long time ago) of the cables in that sub-harness becoming broken, causing problems. The live wire comes from the flasher relay into the handlebar switch as ( I think,striped light green & brown ) wire. There is is diverted as you select with the indicator button to left (Green striped red) or right (green striped white ) indicator lights. Because you say both sides are erratic, that striped light green & brown may no longer be terminated , or be perhaps broken somewhere along it's length. The easiest way to confirm this may be to bypass between the above cables at the plug from the handlebar sub-harness. Hope that makes sense.??
Thanks for both ur suggestions. Definitely makes sense that it could be either. I’ll buy a flasher unit / bypass thing you can pick them up for like £12 and if that’s no fix I’ll have a look into the wires. Hopefully it’s the relay, everytime someone on any forum had problems with the indicators it seems to be the issue. It just confused me because they flash for the alarm but if that drives it directly then that makes sense Amazon do the flasher bypass things so can send it back easily enough if it doesn’t fix anything.
I should have added, flasher unit would be my choice only if you're just changing things to eliminate them, but ideally you'd use a multimeter or even test lamp to check the signals to & from the flasher, as St Marks pointed out there are more possibilities, but it didn't sound like you were going down the testing route. Coincidentally I nearly had an issue with the wiring from the LH switchgear on my bike, caught it before there was any broken cables but the protective sheath split as it was continually bending in the same spot, maybe another thing to check.
Sorry forgot just to close this… got £6 flasher relay off eBay and that fixed it haha. Thanks for all the recommendations and help though at least my connectors are nice and clean now too
