I have a Peg Perego Thomas the tank ride on. It was working a couple of weeks ago but seems to have stopped! When you press the button to go, it does nothing and when you press the sound button it makes a click sound and nothing. I have givn it a really long charge although the charger light is still on orange (so telling me it's not fully charged). So wondering wether it could be that or....the buttons on the front werew stiff after being in strorage for a long time so I lifted the roof slightly and sparyed some wd40 inside. I know rather silly maybe, but do you think this could have disturbed the contacts inside?? Thankyou xx
