JEREZ, Spain, Feb 5 (Reuters) - Mercedes called a halt to their first day of Formula One testing on Tuesday after Nico Rosberg stopped on track with flames flaring briefly around the back of his car.
The team blamed an electrical fault.
"After identifying the cause of the problem, we will not be running again today whilst parts are modified ready for tomorrow," Mercedes said on their Twitter feed.
"The part which requires modification is the wiring loom where the electrical fault originated this morning."
