So my dad took my T/A to the track and after he was done the left headlight won't move. It doesn't make any grinding sound like it would if the gear were stripped. I was just wondering if this is usually a bad connection or if the motor just burnt out.

After he took it down the track he turned the lights on and both came up but when he tried to turn them off onlt the right one went back down.

Thanks for the help.
