Asta ahora todo va bien, si alcanzo a percibir un poco las caídas de voltaje pero es algo muy leve, ya que tengo alrededor de 5k w rms corriendo en este alternador y valla que le suda, hay que aclarar que esto sería imposible en alternador de stock, pero como dije: asta ahora todo va bien con el y nada de problemas eléctricos. Antes de todo recuerden hacer big3 en el, recomiendan cable 0 pero yo me fui con 2/0
