today it happens again!
when i turn on my headlight
the car actually jerks

and when i stop my car (when the headlight is lid and engine running),
when i press my brake, the headlight will dim a while :(
sae thing when i open small lamp, then when i turn on headlight, everything will dim a while.


than i use multimeter to check

at first reading is 13.1 volt (engine not running).

than when i turn on the engine, and test again, shows 12.7 volt. (strange..)

than when i switch of the engine after about 1 minute. the reading shows 12.6 volt


very strange...
