Kalau belting longgar,belting yg mana tu bro???? Rolling Eyes

u said when ur driving suddenly slip to neutral? Clutch slipping? just a guess. When was the last time u changed the clutch?

Kalau kereta susah nak start, alternator kena check tengok. Its time for 90A alternator.huahahaha

My 2 cents

Yeah,it's slip to neutral & battery indicator menyala tapi masih dlm gear,selalunya bila jadi camtu OFF enjin (still tekan clutch coz masih dlm gear & keta sedang bergerak) & start semula & bergerak spt biasa....sambil konfius seketika Rolling Eyes

Last changed clutch about 3years ago...

How to check alternator it's ok or not????

if im not mistaken, try starting the car up. Then unplug the battery. let the engine run, if the engine dies off. The alternator kong. Im not very sure la, i read it sometime ago.

Regarding the clutch, i think if it slips, the clutch system have to be changed le. LUK clutch set. Should be around Rm6++ full set.

I stand corrected. Maybe other members can chip in
My 2 cents

belting alternator tengok ada tension tak....kalau tak boleh slipping...jadi alternator mcm tak pusing...hence the batt indicator on kat dash...esp kalau suden change of engine speed

This is unique problem on which i never face before maybe mine is automatic. sorry bro, i cant help on this.

to ensure the alternator whether working or not, it is advisable to check alternator using amphere meter. kat kedai battery selalu ada. what they do is 'ON' all electrical ie: hazard lights, both lights (high and low beam), radio, aircond. Then they check the power in and out. if in less than out that mean your alternator is gonna kong.

trouble starting also contributes to fuel pump or electrical. Fuel pump relay located together with aircond compressor relay at left side shocks tower beside afm. (not in fuse box). OR starter module located at firewall.

mmmm...... hope it is not ECU.

or u can try this.dari alternator, ada wire positive yg supply power to the car.wire ni jalan masuk kat fusebox sebelum masuk bateri balik.macam wiring meter api rumah. kadag kadang,conection kat dalam fusebox tu longgar.the terminal boleh cair sebab panas and longgar.cuba check.lampu batt on sebab the system detects takde current from alternator,padahal alternator ok.cuba try. mana tau boleh. btw, benda ni dalam fusebox bawah fuse,so kena bukak fusebox tu. insyaallah.....

salam bro... my ride mengalami masalah lebih kurang macam hang la. cuma bezanya prob E30 aku... bila nak tarik or tengah speed tiba2 enjin macam CUTT-OFF dan kadang2 mati terus. penah sekali saya tengah speed kat hiway tetiba enjin mati. so, gelabah biawak jugak la nak lari dari lane kanan ke emergency lane. pastu kena tunggu dalam 10 - 15 minit baru bleh hidup. agak2 sama ka dengan problem bro shul kita ni? memang bikin hati runsing...

yours motronic or Ljet?
If L Jet, check your distributor rotor arm... mungkin haus ALSO please get new Fuel Pump Relay... This relay kekadang dah lama, so the current supply tak mencukupi. Cost new RM75

mine is motronic bro. rasanya... maybe la ada kaitan dengan ECU pasal saya punya alarm auto-lock. tiba2 satu hari tu enjin mati... alarm dengan central lock tiba2 out. terpaksa pakai kunci untuk bukak pintu. dah tu kena buka 1 per satu plak tu (kanan, kiri dan bonet). ada jalan untuk saya selesaikan masalah ni dak?

p/s: sori shul... terhijack thread. kebetulan prob lebih kurang.

Takpa line kelia chaq,sekurangnya aku tau jgk apa puncanya...problem kita lebih kurang sama chaq,cuma aku punya kes enjin mati time masuk/drop gear....bila time nak potong jadi camni mmg gelabah gila la,mmg dangerous!!!
Enjin aku Ljet,byk kemungkinan kalu jadi kes camni,kena check 1per1 yg mana disyorkan oleh sifu2 kita, takut jadi lbh kronik....lgpun membahayakan kita semasa memandu...

Hmm...bleh gak tu,klu ecu motoronic ngam bleh masuk dgn Ljet punya socket bleh la aku try....alternator dh check OK,skrg aku tgh test run after setting idle bg tinggi skit,sbb sblm ni idling agak low,klu still jadi jgk penyakit ni aku akn check another source plak,bila jd camni bkn senang nk detect apa punca sbnr,perlukan masa & kesabaran sbb penyakit misteri aku nih jarang berlaku....tp bila sekali berlaku sendiri mau ingat la!!!

bro dah settle ke blum?
kereta aku pun ada masalah camtu gak...lepas check check ada wire sudah terbakar dekat kawasan mounting absober right side(driver side)
it's not actually a wire, but something like copper(kuprum) connector...
so,,copper tu dah terbakar skit... tinggal halus jer...
aku pun sambung kan terus (by pass) copper tu.. skang dah ok dah..
