I mowed for the first time this year (front yard only). I put the battery back on the charger and decided later in the day to do the back. When I held the security key in I noticed there was little resistance, and the mower would not start. There was a post by user "Steve" here (https://community.egopowerplus.com/ego/topics/mower-wont-start) that matched my symptoms exactly, and I found the same thing when I removed the back cover. The problem I'm having is there is a longer spring than the one that returns the security key, but I can't figure out where that spring should go (it basically fell out when I removed the back cover. Either a simple image of what the internals SHOULD look like with the back cover removed, or some basic instructions would be very helpful here. Thanks everyone.
