Someone helping my wife jump started the car with wrong polarity (Assumed due to current car behavior ). The car went fine for a mile then suddenly ABS light came on, then Battery light, then other random dash lights, speedometer started going crazy and then gears display went off and car stopped. after that it won't start . so jump started again and again same story.
Day 2
took the battery out assuming it not getting enough charge to crank the engine.charged it for 1 hour and then put it back again. car started fine and drove for longer this time but then after few mins same behavior as above. after reading some posts it was suggested that leave the car without battery for few hours and try with fully charged battery. So I took the battery out and charged it fully using a wall battery charger.
Day 3
I have put the fully charged battery in the car and drove for 15 mins (2 miles) and it behaving as normal so far.
I have checked the fuses. everything seems to be fine there.
Now the questions are
-is there a way to check if my ECU is fried
-is my fully charged battery is hiding the any potential problem ?
