Not for me. The JY I use has them off and they are tested. I have had reman go south too. IMO this starter is as close to bullet proof as they come. Over the years I have used many of them and only had 2 go out and one was a drive after many years and miles of short drive that is prone to going out on other starters with the same short drive frequent start ups and the other was a contact set that is a low buck easy repair and they go out on others as well. Do your own thing. Do what ever makes you feel good. Only trying to pass on a $$ saving info. For me I JY when I can and save a buck spend it else where.
