車發電機

我架車萬事得323,99年,去原廠話架車的「發電機輸出不穩定」,有時13.9w,有時13w,換新發電機要8000元!甚麼是發電機?是否「打南毛」?generator?有無需要換?

Re: 車發電機

Yes, 「打南毛」or generator, 99年都差唔多要換, 買二手或翻新應該千幾蚊搞掂, 買全新約二千幾.

原廠行過打聲招呼無問題, 維修就搵外面相熟車房啦.

Re: 車發電機

打南毛一般都好come, 行好多年先會壞, 買翻新得啦, 分分鐘用到你換車都唔會再壞.

唔好番廠呀, 斬到你一頸血, 去車房整啦, 換打南磨唔係好貴既o者!

Re: 車發電機

直流發電機 dynamo 的直譯就是"打南毛"。

原廠話個 dynamo 輸出不穩, 咁有無影響架車呢? "差池" - charge 又夠不夠呢?

$8,000 回廠換唔係咁值, 除非你好喜歡架車就另計。 搵相熟車房 check o下睇o下駛唔駛整。 就算要換都肯定平過原廠好多。

Re: 車發電機

謝謝。再問一個在萬事得做過的人,他話不用全個「打南毛」換,只換打南毛的「炭芯」,幾百元就搞掂,各位車主有何意見。

Re: 車發電機

Unstable output can be a combination of one or more of the followings. Obviously, changing the whole dynamo(the old term, now call generator) will make sure you won't be falling into the trap of treating the head and then the toe needs treatment soon afterwards.

OK, here you go:
carbon brush failure
voltage stabilser failure
magnet/coil failure
bad contact
slipping drive belt

Hope the above help. :-P

Two options:

(1)Buy a new OEM alternator for your car


(2)Re-build your existing alternator (replace
the inside parts) for your car

If the re-build cost (labour and parts) is similar
a new OEM one,then buy a new one is better for
future using)


Ask your car's technician for final decision.


I am facing your same problem!
(I'll rebuild it, the different price is HKD500 in
compare with HKD4K)

Re: 車發電機

有時13.9w,有時13w,無問題的
只要充到電就得
電壓多少同你有冇用冷氣,行夜車.....有關
無需要換無啦啦8000元唔系哇
行到壞錶板會出電池或引擎燈到時換都得

最壞打算都系比$300拖車

$300 VS $8000你點睇

I think it's worth a try. BTW, as battery output is just 12V, and as long as the dynamo can output higher than 12V, your battery will be charged up, only a matter of time. As long as you can start the car I do not think there is a urgent need for repair. To monitor if the dynamo is dead, buy a LED indicator (less than $100) and plug into the cigarette lighter to check the voltage.
