Bad news, and i though this might be the case since the mower/battery is only three years old..I put the new battery in, charge it, and the mower still doesn't start up. So it's something other than the battery. So I have an extra $65 battery.
DIY fail. I had originally called the closest B&D service center, but they were in Manassas and there was going to be a 24 day wait. Maybe you can take it to a place that's not a recognized service center and they'll do it? Anybody know? I think i've only had work done on a mower once in my lifetime and don't remember the details.
