The Singapore Flyer, the world's largest ferris wheel, was being closed for a thorough safety check following a breakdown the previous day, which left 173 people stranded in its capsules, operators said, dpa reported.
A short circuit in one of the drive motors of the 24-capsule wheel occurred at around 5 pm (0900 GMT) Tuesday and lasted for about six hours.
About 10 passengers had to be evacuated from the capsules by the civil defence force team using rope harnesses.
According to a report in the Straits Times newspaper, the flyer had experienced three technical failures since it started operations in February.
One incident was in July when the flyer stopped turning for 30 minutes due to a fault in its braking system. On December 4, it was stuck with 70 passengers when bad weather forced it to stop turning.
The 240-million-Singapore-dollars (171-million-US-dollar) wheel, Singapore's latest leisure attraction, is the world's largest ferris wheel with a height of 165 metres. Its takes about 30 minutes to complete a round.
