OK, so this is telling you that the flasher module is working, the pins are making contact with the plug OK, the wiring is not too badly messed up and switches are operational.  You need to check grounds again, especially under the tank.  Also, check the all of the fuses for continuity.  ATO fuses are NOTORIOUS for looking intact but electrically open.  Pull each and use a multimeter to verify each fuse even though you trust your eyes.
replaced all the fuses with new ones. no effect

Turning hazards on and off activates left indicators. So the left is stealing earth from the hazards (blue/brown from yellow/violet; tl from w)  therefore normal brightness. It doesn't take long to put the test probe in five sockets and reduces the guesswork, also check for touching wires, probably in or near the relay box.

On the left hand side of the bike,  there is a spot where the loom rubs on the edge of a panel, at least it does on mine. 

Unplug the hazards,  temporarily you don't need them.  This will simplify the problem.

Whatchya got.

are you talking about these sockets under the tank or under the flasher module. am I using a meter or test lamp, I'm no electrical genius, I need more specific directions. sorry

It only occurred to me today that there is a high wear spot on the loom at the left side where it rubs on a panel,  this could be an easy solution.

 The hazard plug is under the tank on the left,  just poking out of the loom. Unplug it then see how your indicators work.  It connects brown,  yellow/violet and sometimes white/blue. You can also trace it back from the switch.

Last, if no luck,  you can use a test light to check the looms socket for the flasher relay. Make sure you don't put the probe in the wrong socket.

There is a good chance the loom is simply worn on its underside, on the left, rubbing on a part of the k75s panel,  from memory.

pulled the tank
thought i found the problem as the hazard wires were mashed under a bolt. freed them and cut the black protecting plastic but the wires looked unbroken .The ground tested good and I get continuity from the switch to the plug   when i disconnect the hazard wire plug [brn/yel violet], The turn signals do not work, I get nothing from the right,on the left I hear a slight click at the flasher and a faint flash from the spedo indicator.

Check power on the relay Pin 15 (Green/Black)
Check power on the relay Pin 58E (Grey/White)
If power is present and in spec on these wires, then another thing to try is to open the flasher module and reheat the solder joints where the pins join the PCB.  Sometimes the solder joints go cold and don't make a good connection.
got power and Inspec on the green black got power and Inspec on the green black  donít have a gray white and no marking for a 58E on my flasher module

Daveson, where is the looms socket, is it one of those under the clear plastic protectors, and how do you get them apart without cutting the plastic? mine are not flexible anymore, and exactly how do you test it?
update: got them apart and tested the grounds, tested fine

Has rbm's suggestion in Reply #5 of heating likely cold solder joints within the flasher unit been undertaken yet? If not, why not? I don't see that checked off in the list.
no
the joints look good, no movement , no cracks. I don't have a good soldier iron and am afraid of messing up a possibly good and expensive part. I will see if I can borrow/buy a better iron and get to this if nothing else fixes the issue.

So the indicators are stealing earth because they have none of their own. The clear plastic cylinder thing on the left is stuck to its loom.  Prise something thin in between,  very carefully,  then wd40 or something, then slide it back.  Disconnect the plug, give it a good clean.

I use electrical circuit board cleaner,  but deoxit seems to be the go. Whenever I ask for it in a shop,  I get looked at funny,  I say don't look at me,  l don't know what I'm talking about either.

Clean it as best you can,  then dry it,  put it back together.  Now test your indicators, horn and light  switches. Then do the right side,  then test your switches again, especially on your right handlebar.

On the frames central bar,  on the left,  you will see a bunch of brown wires bolted to it. Doesn't matter if they look good, scrub them, spray cleaner on them, dry them,  clean them real good. Clean each one separately. Test your switches again.

If lucky,  your indicators will now work properly. Look for any exposed wires and wear spots. Then clean all the other plugs. Look on the left,  for the wear spot mentioned earlier. There should be a rubber grommet to protect wires exiting the relay box.

With your fingernail flat on the horn relay and a short press on the left indicator, you might feel a vibration, then that is where the noise is coming from. The left indicator is trying to steal earth from the horn,  but failing, good.

Tried all that, I was not lucky. I'm ready to put the tank back on and see if I can source a not so expensive flasher module. at least I may be able to eliminate that as the problem.

greetings...

check all yourn fuses... they all gonna checks good... right...

replace all of them with new unused fuses...

try it... you gotts flashing... then remove fuse 3 and try it... you gotts nothing or flashing... what is it...

j o
when I remove 3 I gots nada

Before you put the tank back on,  a couple of quick,  easy questions.

How do the indicators work with the turn cancel switch unplugged? It's brown white,  with its own plug,  goes into the plastic cylinder on the right hand side.

How do the indicators work with the instrument cluster unplugged?

Do these tests with the hazards unplugged.

About one inch in front of the normal tank position,  on the front,  left hand side, the loom may be rubbing against the vertical black infil panel,  which surrounds the area where the forks pass through. There could be some exposed wires there.

When the indicators worked like hazards,  were both indicator warning lights on the instrument cluster working, or just the side that you pressed?

too late. put the tank back on. tried to start. no start. did I remember to connect fuel pump plug. no. connected it. still no start. don't heat the fuel pump charging. good grief. I did pull the relays to clean the contacts and they might not have gotten in the same places, but the 3 look the same and have the same part #. I guess I'll be pulling the tank off tomorrow and will get to your questions. how /where do I unplug the hazards and inst cluster?

When I turn the hazards on , then off , the left stays flashing until I turn the hazards off or depress either r or l turn switch.

Actually leave the cluster plug till last, I was about to delete that as it is not quick.

The hazard plug under the tank, towards the front and left side. You unplugged it before with the result that the indicators stopped working.

Did you reconnect the hazard plug?

So you have cleaned all the items on RBM's list except the indicator switches.

I think if you clean the left indicator and horn connections, your left indicator will then work.

Then clean the right, and the cancel switch.

You gotta do it in a bucket or something, so you don't loose springs and stuff that might fly out.

so do you take them apart by loosening the small philips screw inside once you take it off the bar? then clean

I havn't had to do it yet.

You could read up on it first or just go for it and see how it goes.

Try this shortcut before dismantling the left switch. With the switch removed you will see where the blue/brown wire has been soldered  at the back. With a test light clip connected well to the battery negative post, touch the probe to the blue/brown soldered spot.  Scratch it well for a good contact, or with the probe flat for a longer contact area. The left indicators might now work, then you know that the left switch has failed to provide earth and you need to dismantle it. The help of the probe might even shake things up a bit for the switch. Try with the probe and pressing the switch. No luck first time,  give it a few goes. Or even better, a jumper wire with a fuse.

The first thing that I do on a non starting bike is check the spark plugs. Are they wet or dry???
