well my four-wheelerr stopped working out of knowhere while i was riding it. before we had to jump it off but we thought it was the battery so we got a new battery and charged it and put it in but that was not it. we went to the store we bought it from and they said its either the main starter fuse blew or the SDI is fried they also said that its most likely the main starter fuse. so, if anyone could help me on how to fix my problem i would be grateful, thank you
