First you are stuck in this thread until you get full membership read this ;https://www.kawasakiversys.com/forum...ber-intro.html
Couple places you need to check & clean, the engines ground and the frame ground, engine cn be accessed from the footbrake side of the bike, this is the 8 gauge wire coming from your negative post of the battery. A very common problem, my 07 was corroded, I have a post on this as to removing the aluminum oxide using a red scotch brite pad ( those sponges for dishwashing have them, actual scotch brite come in red ( prefered) , green, and white.) Use a copper based Kopr cote or really good dielectric grease https://www.canadiantire.ca/en/pdp/p...3747p.html#srp
Next you need a meter that reads volts DC, connect across the start solenoid contacts. Two things, 1st make sure the solenoid is pulling in. No time for pin outs today but the 2 lighter wires are the coil circuit the heavy wires , one is positive from the main fuse and the other goes to the starter.
What you want to do is connect across the start contacts, you will read the battery voltage or you should. This is what to look for, watch your meter, you should here the start relay click
which is under the gas tank, if nothing happens, connect across the small wires of the start solenoid
, try again this time you should hear the start relay
click under the tank and also get your battery voltage, again if no turning over and you got the voltage across the coil circuit. Next test, pushing the start button, feel if you are getting a clicking at the solenoid, this is to establish the coil circuit, it is possible to have the start solenoid coil open circuit , if this is the case you will not have a headlight as the headlight uses the start solenoid ground
Notice start relay and start solenoid , yes two devices, the solenoid carries the start current and is likely at fault.
Watched your video , money is on the solenoid, however I definitely would check the engine ground. The way it is is excellent for proving this, one further test to do, go from battery positive to the small wires, one should read slightly less the full battery volts, the other should read full battery volts ( the full volts is the coil ground)
If you get the coil circuit of the solenoid engaged 5 out of 5 tries, and read full battery volts across the solenoid load contacts, your solenoid is pooched. Again that engine ground is 100% important to check.
