i dont know..
i just bought a brand new battery.. an optima yellow top actually. my old battery wasnt completely dead, just getting there. i figured i might as well fix it before im stuck on the road somewhere. so whenever i installed this battery, i tested the alternator the same day and it tested good. cool. 2 weeks later my brand new optima is on the verge of death. i kept my old battery just in case.. i went ahead and put it in so i can get to work tomorrow. the battery light is still on... i dont know what to do. i was researching relays in the catalog at work and saw some relay called a batt charge relay... never heard of it but apparently its there. think this could be the source of my wows????
