OffshoreMig Posted January 31, 2021 Share Posted January 31, 2021 (edited) Hi. brother-in-law has a Honda Click 2012 and it is not starting Starter motor works. There is no spark We took the spark plug, spark plug lead and coil and tested it on another bike and spark is good and strong. Could CPU be problem? how can we test? Do not have a spare one to replace and test. New one costs 700THB ThAnks in advance Edited January 31, 2021 by OffshoreMig Link to comment Share on other sites More sharing options...
VocalNeal Posted January 31, 2021 Share Posted January 31, 2021 Does a Honda Click have a side-stand switch? Is the brake light system working. Brake lights on when the lever is pulled? 1 1 Link to comment Share on other sites More sharing options...

Brake lights on when the lever is pulled? I think the starter motor also wouldn't work if the kickstand switch would be faulty, so probably not. Just take it to some random motorbike mechanic, shouldn't take him too long to figure out what's wrong. 1 Link to comment Share on other sites More sharing options...
VocalNeal Posted January 31, 2021 Share Posted January 31, 2021 (edited) Is there a run/kill switch on the handlebars? Edit: Would appear that the brake circuit will stop the starter being operated so if the starter turns then it is not the brake circuits. Either the run/kill switch is in the "kill" postion or the side-stand switch is broken or not operating. As side-stand is under the bike and subject to water,road grime etc......

JayClay Posted January 31, 2021 Share Posted January 31, 2021 This happened to me once. What had happened was a rat had somehow gotten inside and chewed through the cable that connected the safety mechanism (that prevents the bike being started when the side stand was down) and the ignition. Long shot but worth checking. Link to comment Share on other sites More sharing options...
teacherclaire Posted January 31, 2021 Share Posted January 31, 2021 (edited) You can try and see if both wires at the kickstand are connected. If yes, you could connect/bypass the two wires of the kickstand and see if it starts. If that doesn't work, I'm afraid it's the CPU. We had to change the part on our little Yamaha 110 cc four times now. Edited January 31, 2021 by teacherclaire 1 Link to comment Share on other sites More sharing options...
ctxa Posted January 31, 2021 Share Posted January 31, 2021 The starter motor is controlled by a relay. That relay is at the same time controlled by the CPU. You have to find that relay, make sure the relay is not bad. Think of a relay as a switch, when the CPU tells it to close the starter motor cranks the engine, when CPU tells it to close it just cuts power to the starter. Find that relay, and check whether the CPU is giving the order for it to close. 1 Link to comment Share on other sites More sharing options...
cali4995 Posted January 31, 2021 Share Posted January 31, 2021 (edited) i just bought an older honda click last week that had been sitting . if it's actually " cranking" than your ign. switch, kickstnd safety switch, front brake lever swtc are all functioning. and obviously battery capable. the starter relay& motor working as well. migwelder seems to be scratching at cause as we speak. mine's a few years older has magneto& cdi pack but no cpu. let us know how you make out. try a known good piece your idea Edited January 31, 2021 by cali4995 1 Link to comment Share on other sites More sharing options...

The Starter motor turns over It (the problem) is intermittent. Some times it works and other times it does not. Starter motor kicks over - No Spark. We are gong to replace the CDI. A bad connection in the CDI can cause this fault. Other possible cause we think could be the stator We will run a multi meter over it Thanks Link to comment Share on other sites More sharing options...

How can I test? We will buy a new one as I read that the CDI can have a soldering connection problem. Sometimes heating it with a heat gun helps. This could be the cause of the intermittent loss of spark. I hope it is not the stator. But that is next on our list. Will do a wiring check again to make sure. but all looks good in the wiring front. Thanks in advance Edited February 1, 2021 by OffshoreMig Link to comment Share on other sites More sharing options...
cali4995 Posted February 2, 2021 Share Posted February 2, 2021 (edited) don't think there is a multimeter test for cdi . having said that , found one on my mio , one of the wires leading into it was cut and bare-spliced back together golly gee rotor-stator-rectifier issues do seem unlikely but maybe it has 100k on it who knows. wear a white lab coat & spectacles that seems to teach the beast who's boss Edited February 2, 2021 by cali4995 1 Link to comment Share on other sites More sharing options...

I read tat dry solder joints is an common fault You can heat the CDI box with a heat gun and this can fix intermittent problems. If the fault come back I will post and update Thanks all for your advice and comments. I am pleased it was not the stator Link to comment Share on other sites More sharing options...
NCC1701A Posted February 4, 2021 Share Posted February 4, 2021 does anybody know what year Click started using CPU? Link to comment Share on other sites More sharing options...

A new bike will usually have more than one processing unit. If a bike has fuel injection it will at least have some kind of CPU. The Click comes with fuel injection since 2011 according to Google.

cali4995 Posted February 4, 2021 Share Posted February 4, 2021 (edited) my 2006 click 3,500฿ project bike just fired up. no keyset. 1/2 L fresh petrol . home 220v on-off switch. crusty brake and starter switches. im immensely pleased getting seat open biggest ache in head think click went fuel inj about 2011 , like you said. yamaha mio same. they sell diagnostic plug in tool. for some reason scoopy had fuel inj few yrs earlier. and had probs with that. you hear them crank & crank , sensors bad i guess Edited February 4, 2021 by cali4995 Link to comment Share on other sites More sharing options...
