JD'ers please be judge and jury and tell me if I'm wrong. I had a customer come in on 3/17/2017 and buy a CDI for a Polaris Dragon. They asked me for a discount and I told them both we could not discount the new CDI but we would program it for them. They were so happy that we had the part! Now over 2 months later we get a stop payment. I contacted the customer and of course they tell me that the sled only made it 3 miles and the new CDI burnt up. I said I'm very sorry but we cannot warranty electrical parts once installed. They went on to tell me that we should've known there was something wrong. We informed them that they may want to replace the Voltage Regulator as this could be the cause of their problem which we also made them aware of that at the time of purchase but they did not feel the need to replace it. SO, are we to blame for their misfortune? I cannot understand these people and how they think. They paid for no service. They wanted to buy part only and we made that happen. Now they can just stop payment and that's that? This person is also the President of a snowmobile club in MN. Talk about tick a guy off!!!!! We did not service the sled, only sold a part for it!!
