Red Bull Racing are determined to get to the bottom of the team's mechanical problems in the wake of Sunday's disappointment in Italy.

Reigning champion Sebastian Vettel endured problems with his alternator throughout the weekend at the Italian Grand Prix and was he was forced to reture, while team-mate Mark Webber was also unable to finish the race.

Vettel, who claimed second place in Belgium, fell 39 points adrift of championship leader Fernando Alonso as a result of Sunday's failure with seven races remaining.

And having experienced similar problems at the Valencia Grand Prix, which ultimately cost Vettel victory, Red Bull and engine partner Renault are aware the problem needs to be rectified immediately if the German is to defend his title.

"It was a hugely disappointing race – our first non-scoring race since Korea 2010," team principal Christian Horner said.

"It was a repeat failure with the alternator on Sebastian's car and we need to look into and work with Renault to ensure it doesn't happen again.

"It's already cost us a victory in Valencia and now a points finish again here in Monza. It's important we address it for the remaining seven races."

Webber, meanwhile, is confident the team will return to winning ways sooner rather than later.

The Australian had no engine troubles but flat-spotted all four tyres with just two laps remaining in the final European-based race of 2012.

Despite falling 47 points behind in his bid for an elusive drivers championship, Webber is staying positive."It's been a frustrating weekend," he said.

"With Seb (Vettel) retiring as well, this was a poor day for the team. It was our first double retirement for 34 races (Korean GP 2010), so clearly there's work to be done.

"But we're a very strong team and we've got some great people in it, and we'll fight back. "The company philosophy is win or nothing, we've had a few good wins this year and we need to get back to winning ways as soon as possible."
