If not I'd go buy one from the auto store (assuming this is a ka24) plug it in run on it and see if it fixes your power issue. If not just make up some BS tell em it isn't fitting or something or that it isn't working and you want your money back cause you just got one from your friend. Or before you buy it get the persons name who's helping you and ask him whether it's okay to return it if it doesn't fix your problem.
