hi all..
my old car (datsun 120y) got problem need help.

ok i traveling...
then i notice something strange. when i press brake or put signal,
the light will dim for a moment, then back to normal..
(seem like battery not conencted? when need electric, the alternator cannot giv that much
usually the battery will 'stablelize' so we not see the 'dim')

then i wan to go toilet.. i stop by a petrol station
then there is few bump on the road, and just when i turn into the station
whole car die! everything electric not functioning
(lucky if not on the road,.. if not i cant even turn on the hazard light)


ok then i try to start.. cannot
even the 'battery' light on the dashboard not lid
then cabin light also no light.
just like everything electric just down.


so i go to toilet lar..
then after i 'do small business'
i come out open the bonet
and touch here touch there the wire
then can start again! (but seriously i not do anything.
cause i dono what to do)

now the car can move, but no air cond (no wind)
then after i drive a while.. air cond back..
then after few minute, air cond down again.

then later on the air cond back
then i use until today also no problem

so anyone know what have been wrong?
how can i check? anyone can help?
