Alonso hit with electrical issues in Indy 500 practice

Fernando Alonso's mission of winning the Indy 500 started on the wrong foot in practice after his McLaren Chevrolet suffered an undiagnosed electrical issue during opening practice.

The problem forced the Spaniard to spend much of his time on the track massively down on power. He ended the session 32nd of 39 runners.

His top speed on the opening day was just 224.162 miles per hour, massively down on defending Indy 500 winner Will Power's 229.745 mph benchmark.

McLaren could not solve the problems during the day leaving team principal Gil de Ferran frustrated for his team and driver.

“I think the plan here was to run more than we did,” de Ferran told NBC Sports.com.
