On the 8th, on the second day of the 2nd Barcelona test, Honda launched a new spec. According to Hasegawa Yusuke, general manager, "It was originally designed to introduce this to Melbourne" and was scheduled to be used from the first day of the second test.
However, due to the trouble that occurred on the second day of the first test (February 28), although the cause has not been identified yet, arrival was delayed because we had taken countermeasures. In other words, the electrical problem that occurred on the second test day (March 7) was old (exactly the same as the first test) spec.
"Electric trouble of Stelle (occurred on March 7th) caused insulation failure, and a symptom occurred suspected of a ground fault (electricity flowing in contact with the ground). The F1 machine of the F1 machine is equipped with a regeneration system and high voltage current flows, so both plus and minus are completely floating from the car.When it contacts the ground either way, it becomes a ground fault, but now F1 Even if the high voltage terminal is covered with insulation material such as rubber, it will become ground fault when it comes into contact with the ground.The trouble this time was also completely short-circuited There was only a warning because the insulation resistance fell below a certain level. "
"Because this kind of trouble happens even with a slight insulation failure, restoring is not so difficult, but since it is a hard work to find where insulation failure is occurring, replace each power unit "Hasegawa General Manager said.
Well, Honda's new spec was introduced on March 8, but Fernando Alonso took 46 laps this day, and it was no trouble about the power unit. According to the team officials, according to the team officials, 27 laps in the morning, although he did not reveal "Why can not I tell from my mouth" why the power unit did not have problems with laps? It was said that there was a problem of water leak on the side of the car where I ran.
Of course, even as a Honda, I can not be relieved yet just by saying 46 laps trouble. But it is certain that he has advanced forward one step at a time.
"It is undecided whether to use this in Melbourne at this moment. If the cause (of the trouble of February 28) is clarified in the future, based on this (the new specs used on March
, the opening race I will do whatever I can do to improve reliability up to the point. "
