Solved - Indicators/Blinkers stopped working suddenly!

If your turn signals have stopped working, it'll be doing one of these things: blinking rapidly, coming on without blinking, or nothing at all. The good news is that all of these symptoms point to two possible issues, a bad turn signal relay or a dead bulb.

Thanks for getting back on this. I need to clarify something here. When you refer to 'relay', are you referring to the flasher unit (under right side cover)? Or is there an actual relay located somewhere else that I have missed?

Also, can a single blown bulb actually shut down the whole indicator 'network' in these?

Re-check that fuse. Take it out and replace it with another one to verify good or not. I personally advocate replacing all fuses with the EZ-ID or Smart-Glo kind that light up when they go bad. Only negligibly more $ than the regular ones. Makes finding a problem so much faster. And have spares! If you buy a 'master' fuse assortment, around $30, you will have all you need. Cheaper that way.

Firstly, check if your turn lights work properly. · If one of your signal lights doesn't come on, then you check the bulb; check the bulb socket ...

Hi folks, I realised on my ride today that all my indicators/blinkers are not working (1800C,30K kms). Have been faultless up until now.

I've cleaned out the switch on the bars (which seemed to be working ok previously, and not that dirty). No change.

I've checked the fuse,which is fine. No luck there.

I've multimeter tested the turn signal relay (I have the 9pin block with only 5 wires going in). No sign of life there (when indicator switch is activated either side). Completely dead.

I've removed my turn signal beeper kit (with hazards option) in case there was an issue there, and checked the remaining wiring. No luck.

I've checked the connectors in the light bucket in case loose etc. No luck there either.

There's no life in the green turn indicator on the 'dash' (on the tank).

All other electrics are working fine (incl. hi/lo beam, brake light (foot and hand).

So.....what am I missing?

If you are testing for power at the relay, the white/blue wire in the corner of the connector should have battery voltage with the ignition switch on. I am confused as to why you only have 5 wires going to the 9 pin relay. The nine pin connector should have 7 wires going to it on the C model.

All fixed. It was the fuse.
What I didn't pick up on was that there's an extra fuse box along side the main one. This was the one with the indicator fuse. Funnily enough, the labelling on the main fuse box (which made reference to the indicator fuse) send to match with the main fuse box layout, but there appeared to be a 10 amp fuse in its place. Which on the end was for something else.

Appreciate the input, thankyou.

As for the 5 input wires to the 9 pin relay. That's got me stumped. I saw another post with a photo of the same setup. Perhaps somewhere in the loom the indicators are paired together and share a common point on the relay, instead of 2 separate ones. If they were individually wired in, they'd occupy a total of 7 pins which correlates with the workshop manual. Alternatively, pairing the lights would occupy 5, as is in my case.

Appreciate the input, thankyou.

See response in next post reply - it was the fuse, but I had not seen the extra fuse box hidden next to the main one!

Thanks everyone, solved. It was the fuse, and likely the original one, putting it at 17 years old.

I'm going to check all the indicator bulbs in case they triggered the surge.

The whole exercise did show up 2 things to note.

1. There's an additional, narrow fuse holder (with cover) which sits next to the main fuse box, which can easily be overlooked. The labels on the lid of the main fuse box include the positions of the 2 additional fuses in the extra box (which sits on the battery-side of the main fuse box) but look like they refer to fuse positions in the main box.
2. The flasher relay is a 9 pin unit. The workshop manual shows 7 pins are used (05 2800C). However, mine and others apparently, only have 5 pins in use. I expect this may be because the indicators are paired, and share a pin, which mean only 5 pins are used.

I've not bothered testing the individual pins to see if that's the case - for another day perhaps.

This happened maybe because your flasher wire is faulty or not connected or its fuse. This mostly happens when the relay connection or bad turn signal relay is not working properly. As result, the indicators stopped working. The other reason for this is a broken or faulty wire in the indicator circuit can interrupt the current between the indicator or hazard light bulb which caused damage to the indicators.
