Four electric WikiWiki shuttles at Honolulu International Airport were taken out of service today for inspection following a fire last night that destroyed one of the vehicles in the fleet, state Transportation Department officials said.

The fire was caused by a short circuit in the electrical generator wiring, DOT spokesman Scott Ishikawa said. Officials will inspect the other four vehicles to determine if there is a problem with the wiring.

The $165,000 electric shuttle destroyed was about five years old, said Ishikawa.

The state recently bought three clean-diesel powered shuttle buses that are already being used, added Ishikawa.
