So I'm new to this hybrid cars thing and I bought a 2000 insight for a mph car. Everything worked correctly when I bought it,phenomenal mileage and all. one day the ima light came on and I never thought anything about it,what is this telling me? Are the batteries bad? Could it be the grid charger? Because it no longer charges my 12v up front and causes that to die, which causes no spark. Therefore non driveable... Any help is greatly appreciated on diagnostics or the best route to fix, Thanks!!
