Today way back to home Charging(Battery) light started blinking along with Lights(parking) light, turned car on/off several times but it didnt go. when i got to home, i tried to tighten ECU connections/no then i tighten connections on engine (connectors) and it went off!
didnt get it. i was like 'man, i havent touched any wires regarding this' dont know why it happened. engine seemed heavy then,lesser pick.
Secondaly, i took the meter out today and it was like this:
checked that you were right about purple wire, point i found was going right into it!
purple wire was going into this dark room, i first checked with OHM meter that if wire is completed circuit with any other connector of old disel wiring/other meter connectors/earth it did not show any sign, did same with Voltmeter by putting the ignition to 'on' state , still no sign of connection.
Which meant that the wire you were pointing to, is not connected with any other thing
So, i disconnected the wire and connected it with new wire to ECU SPD. is that Okay?
