05 HONDA METROPOLITAN TRY TO START AND IT HAS A CONSTANT CLICKING SOUND COMEING FROM THE RELAY IVE TRACED ALL POWER AND IT READS BETWEEN 12.3 & 12.6 EVERYWHERE

Hi, Tiny before testing any electrical component in the Starter Circuit it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead-acid batteries. Depending on battery voltage starter relays and starter solenoids can make the same noise when you hit the starter button. You can easily determine which one is at fault by two simple tests:
STARTER RELAY- place your thumb and index finger on the starter relay and press the starter button, if you feel the click then the relay is faulty and needs to be replaced.
STARTER SOLENOID- bridge the positive and negative poles of the solenoid with a small screwdriver if you get a loud clunk then the solenoid needs to be rebuilt or replaced as necessary. If the engine turns over then replace the starter relay.
A motorcycle starter relay is an electronic mechanical switch that has a small coil winding around a piece of metal that requires low amperage and thin wires to be activated. When you turn on your ignition switch power 12 volts is sent to the relay coil which in turn becomes a magnetic contact point that pulls a spring-loaded contact point to itself completing an electrical circuit that allows more amperage necessary to be accessed by the starter solenoid which in turn acts in the same way as the relay but on a larger scale with its stronger heavier contacts making available the necessary amperage to turn the starter motor. If your battery has low voltage it, in turn, makes the magnetic contact point weak in trying to pull its counterpart to make a connection. These relays are usually encased in a plastic housing that is sealed, depending on the quality of the product. When activated they will produce a small amount of heat to their metal components which in turn can create the perfect environment for condensation to form depending on weather conditions and how careless you may be with a water hose or sprayer while washing your bike. After a period of time, several months to several years depending on the circumstances this condensation is the starter button for electrolysis and the slow build-up of corrosion which ends by preventing the magnetic contacts in making a solid connection and alerts you to this situation with the customary greeting "CLICK or BUZZ" if you get a single loud "CLUNK" then the starter solenoid is at fault and needs to be rebuilt or replaced as necessary. The relay is inexpensive and needs to be replaced however in a pinch they can be forcibly opened cleaned and resealed with silicone. In a nutshell, motorcycle starter relays take in low amperage and send out higher amperage when activated and for curious minds, the voltage remains constant at whatever your battery reads at the time.

You have a bad battery or disconnected something . Major disconnect. I own piaggio equipment many of.. the clicking is also a known issue with start relay being way underated it's 50A and should be 100 min. There's a recall or upfit look son A1 site out of Texas. . Clicking is start relay . Not getting enough juice . Battery is low . . Or no good usually. Get something in their besides a 12 Y battery try a 15 ETX DEKA

the starter solenoid is worn and gets hot from engine--replace it--get a repair book from fixya or online

Hi there.....
I was browzing around for the specs of my 05 CR-V in Singapore when i saw your problem.....The sound should sounds like a loud clicking noise of the rearwheels gear area I believe if the sound is coming from the rear. It could be your diff oil that needs to be changed.
Mine was like that & problem solved with the DIfferential Oil change.
