Huntington hasn't won in this series since the 1993 team led by Tony Gonzalez edged Edison, 10-7.
The scoreboard was out of commission at Cap Sheue Field and the teams had to rely on the game announcer and officiating crew for time remaining in each quarter. It cost Edison a scoring opportunity late in the first half.
"It's a big win for us," Edison Coach Dave White said after his team improved to 6-2 overall and won its third-straight. All three wins in the streak have come against Sunset competition and puts the Chargers alone in first place at 3-0 with two games to play.
Huntington saw its five-game win streak snapped and fell to 6-2 overall and 2-1 in league.
"They're a good team and we knew this would be a tough one," White continued. "We tried to give it away again, though. We almost gave it away to Los Al (a 10-7 Edison win) and we did give it away a few weeks back to Mater Dei. Tonight, we stopped them late and held on.
"Like I said, this is a big win and it puts us in the driver's seat."
Neither team scored in the second half after Edison, ranked No. 10 in the CIF Pac-5 Division, had taken a 20-14 halftime lead. Both the Chargers and Oilers had scoring opportunities in the final 24 minutes but squandered those chances. Huntington turned the ball over on downs midway through the fourth quarter, and turned over the ball twice in the final five minutes.
"We had our chances, that's for sure," Huntington Coach Eric Lo said. "I thought we played hard and they played hard, and I thought that there were some questionable calls. But we're not going to hang our heads. We still have two more league games left, starting next week with Los Al."
