MODENAS CT100: FUSE NEAR THE BATTERY ALWAYS BLOW. WHY?

Several month ago, i am facing one major problem where fuse for my modenas ct100 keep blowing whenever I replace new fuse.
Figure: fuse location is marked with arrow
with broken fuse, brake system lighting, signal and horn will not work. plus, the battery will not charge. So, my motocycle operate using magnet coil. So, only headlamp work.

 Common problem with blowing fuse is due to the short circuit somewhere in the wiring system. So, troubleshooting the problem might take some time and will need to trace all the wiring from battery to every end circuit.

 refer to electrical wiring diagram shown in the link here:
modenas ct100 electrical diagram

Figure: troubleshoot the problem require removing all the cover

in the end, it was just due to the wiring insulation damage that touch metal body..thus, causing short circuit, which lead to high current passing through the fuse. then blow it. fixing the cable insulation help it. in my case, cable is cut, then, insert heatshrink tube and resolder the cable. 

hope this help. Thank you

      Hi wan, in my case, wire supply touch the body near the tail lamp..this was due to the metal structure movement from the storage box weight.

HONDA RS150 TPS: RPM TAK STABIL BILA NOT ON THROTTLE DAN PENYELESAIANNYA

Assalamualaikum dan salam sejahtera Isu TPS ni berlaku pada tahun lepas, Ogos 2020 (milage dalam 24000km, baru dua tahun pakai) sewaktu saya on the way ke KL Masa tu tunggang motor full throttle yang menyebabkan RPM nya selalu mencecah ke CUT-OFF (utk makluman, honda RS150 saya ni tak guna ECU custom, masih guna yang standard). Jadi saya perasan, bila selalu tunggang pada RPM yang sampai CUTT-OFF, ini menyebabkan kesan tak baik pada TPS..jadi utk yang belum jadi problem TPS ni..boleh la cepat ganti ECU ke ECU yang tanpa cutoff. APA TU TPS? TPS bermaksud Throttle positioning sensor..bahasa mudahnya alat ni bertujuan untuk mengesan kedudukan throttle body valve dimana udara masuk ke enjin untuk pembakaran. Dengan itu, baru la ECU tahu berapa banyak bahan bakar yang perlu utk pembakaran berdasarkan bukaan valve tu.  Bila TPS dah problem, TPS akan memberi maklumat yang salah pada ECU berkenaan besar mana valve tu buka, jadi nisbah bahan api dan udara jadi tak betul la. maka, tu yang ja...

HONDA RS150 IACV: IACV PROBLEM? RPM NAIK TINGGI BILA HIDUPKAN ENJIN?

 Hi semua, Salam sejahtera Masalah IACV saya berlaku selepas isu TPS wujud di milage 24000+km..kemungkinan kedua2nya ini saling berkait. Masalah IACV hadir ketika saya on the way balik semula ke Johor, ketika bahan bakar berkurang dari tangki moto. SIMPTOM  ? bila hidupkan enjin honda RS150 saya, RPM akan naik tinggi dan kadang2 sukar dikawal. tengah jalan pun, jika stop di trafik light, rpm akan naik tinggi dan mengaum bising..so, isu ni biasanya disebabkan IACV IACV APA TU IACV? IACV bermaksud Idle Air Control Valve. bahasa mudahnya nak control udara masuk ke ruang pembakaran sewaktu motosikal kita idle (tanpa pulas pendikit atau throttle) iaitu semasa tak bergerak. FUngsi dia mcm choke la pada motor lama yg guna karburator supaya moto mudah di hidupkan dan dalam masa sama injap dikawal dan dikecilkan bila enjin motosikal telah panas. IACV idling control valve (anak panah, lubang udara yang dikawal) APA FUNGSI IACV? Jika kita dah pulas throttle, IACV dah tak digunakan dan va...

KENWOOD PROSPERO KM280 NOT WORKING..WHY?

Hi, Peace upon you all. This afternoon, my wife's food processor Kenwood km280 suddenly dead..she planned to prepare Dorayaki for us all, to eat in the evening. Fig 1: Kenwood KM280 mixer/food processor Unfortunately, after pours mix all the ingredient into the bowl, switch On the main plug and adjust switch knob to no 1 speed, nothing happens. After many tried, after referring to the manual that comes with this food processor (KM280), she gives up and asks me to do something about it. The first step to troubleshoot the problem is to check the power from the main plug and also the fuse. The outcomes are all well and working fine. Second, check the internal connection and gearing, visually. the reason is to make sure no visible damage to the cable and gearing. This will require disassembly of the top cover. It can be done by removing six screws under. after top cover is removed, internal circuits, motor, and gears (figure below) can be observed for any damage. Fortunate...
