Hi, I am a proud owner of a K reg pajero 2.5 and after taking to a mechanic have learned that my baby needs a new alternator. after waiting for a week for the mechanic to get bk to me with a price ive decided to buy my own and get my dad to fit it, the only problem when looking for a new alternator ive noticed theres heaps with different amps. how do i know what one i need? thanks in advance, hope to get my baby back on the road asap!!
