I changed out my ehc for the wire plus about two years ago. I am still not sure it was a bad ehc. In the near future, I plan on sending it to curtis to check out. I would check all your connections including the key switch before spending the money. Seems like someone on here switched to the "m" unit and had a bunch of trouble. might want to do a search.hello mr P. Have a few small issues, like starter getting stuck, sometimes ( maybe 2 times bike just shuts off). Plan on taking a few long trips this summer and just want to make sure no issues on the road by myself. I like the idea of removing the ehc since it seems to be an issue with so many.
