Terengganu's maiden victory came after a 2-0 win over Perak at the Sultan Ismail Nasiruddin Shah Stadium, Terengganu.
After two draws and three losses, Elavasaran's men finally found their rhythm to dispatch the high-flying Perak team.
Ashaari, fresh from international duty, scored the opener for the turtles in the 14th minute after escaping two defenders.
Perak tried hard to fashion an equaliser but it was Terengganu who found the second goal with an effort from Effa Owona. It was created following a strong run from midfield by G.Puaneswaran, who then fed Owona to blast home a shot from outside the penalty box to give Terengganu a comfortable lead.
However, the game ended badly as Terengganu's Ismail Faruqi and Perak's Mohd Nazmi were sent off after a quarrel just two minutes before the final whistle.
