On a Yamaha you are going to have to break open the electrical box , yeah I know it sucks just do it , next unplug the positive wire coming off the starter relay that goes to the fuse , with the battery hooked up touch the bullet connector to the battery post on the solenoid , if it starts bad solenoid bad fuse or bad start stop switch.
Ok so now you need to know which is bad , fine where the start stop switch wires plug in at there are two connectors , one has a black and a white wire, one has a red and a brown wire, unplug both , now leave the red brown connector unplugged , plug the black white connector from the switch into the red brown connector from the electrical box , hit the stop button which is now your start button, if it starts bad bad start stop switch , it's most likely going to be the lanyard part of the switch.
Ok lets say it still does not start , find a set of jumper cables and go from battery negative post to somewhere on the engine that will make a good grounding point , hit the stop switch , what you are doing here is bypassing the negative cable , if it starts bad negative cable , if it doesn't go from the battery post on the starter solenoid to the battery positive post , now you are bypassing the positive battery cable , try it again, if it starts bad positive cable.
Lets say it still doesn't start unhook the jumper cable from the battery hook it to the starter post on the solenoid then barely touch it to the positive battery post, I said barely and make sure you follow this exactly because if you hook it to the battery first you are dealing with a high amperage live wire , you do not want to do that , what you just did is bypass the entire starter circuit taking the solenoid and start stop switch out of the equation..
If It tries to crank over when you touch the jumper cable to the positive battery post the starter solenoid is dead , if it doesn't try to crank when you touch the jumper cable to the battery positive the starter is toast .
Again and I cannot stress this enough ALWAYS hook to the solenoid post first then barely touch it to the positive battery post IN BOTH OF THOSE TESTING PROCEDURES..
I just did this on a Yamaha 1100 Waveventure a few weeks back ,SBT motor, whoever put it in put a jacked up bolt in where the ground cable hooks to the starter , the bolt tighetened up but it did not tighten the cable end against the starter , using this procedure I diagnosed that issue in just a few minutes.
Same method works on a Kawi , wire colors are of course different and you will be going in the e-box to check the start stop switch wires out . but not the starter solenoid .
One more side note , of course you can do the start stop switch test and the negative battery cable test both without going into the electrical box on a Yamaha only.
That's the quick and dirty, no multimeter needed.
