First I bought a voltage regulator for my bike from this person who is a ebay seller. That regulator lasted only 1 week. I was told I needed to change the regulator and the stator at the same time. I then purchased both items from this seller, had them professionally installed and they lasted about 2 rides. In the first instance, not only did the regulator fail, my battery was fried as well. In the second instance, I bought insurance offered on the site of ebay at check out from a company called Square Trade. When the items from second purchase blew, I made a claim with Square Trade and Square denied my claim and told me to contact the manufacturer of the parts (like I knew who and where in China to call) and refused to honor the insurance contract I paid for. I contacted the seller, Caltric, explained that both parts failed, that it cost me 400. in labor to have the parts installed and that it will cost another 400. in labor to get the parts out. The seller, Caltric, was not helpful at all and besides his parts failing, my wiring harness and second new battery were damaged because of his junk faulty parts.
