I live at home with my folks and we rotate vehicles (My Accord one day, my Dad's Legend the next), and my Dad just HAD to use my car even with a charging system problem
Anyway, He comes to pick me up from yesterday night (3:00 AM), and I notice that the headlights seemed really dim.
I knew something wasnt right, and then my dad tells me that he has been driving it around at night with that light on (I know thats bad, but I checked the alternator/water pump belt, and it was fine).
Anyway, about a mile from home the turn signals stopped working, and the check engine light started flashing erratically (when that happened the car started running really rough), then the engine died.
Now IIRC when the battery is really low the check engine light will come on because there isnt enough power to run ECU (let alone the Injectors and the fuel pump), so it goes into backup mode.
Anyway, My Dad and I managed to get the Accord home today, and I check the battery water level. The cells were empty, so I put water in them (but I have no way to charge the battery right now, and I don't have any jumper cables at the moment).
Anyway, my question is:
Could there be any damage to the electrical system because of this?
