Renault Laguna 2004 - car ignition/dashboard light not on - ayo
I have a Renault Laguna 2004, 1.8 16V engine, 5.40 litres, mileage: 90,000km
The battery was flat, tried to start with another car battery using a lead, I made a mistake in connection which I correct immediately the battery sparks, so I started d car, allow to run then move got to my destnatio, switch off, remove the card, parked for about 5 hours, then by the time I got to the car I insert the card, but the card reader will not read the card, so ignition light did not come on, car refuse to start.
I changed the battery terminals, tried another battery all other lights in d car come up, but is like d car is not reading the card so the car cannot do self check, crank the engine or start the car
