Black & Decker CM 1936 -- "kill bar" doesn't work. Put key in starts up immediately.
Hi All, My 10 yr old and I just took apart the control box of our CM 1936, Black and Decker cordless 36V. We were trying to figure out why the "kill bar" isn't working. Usually you have to push an orange button and pull down the "kill bar"/lever to start this mower. We just changed out the battery, and when we did, this new issue happened. You put in the key and the mower starts up immediately. No more orange push button, no more hand lever needed. To stop the mower you have to take the key out. The "kill bar", or hand lever, no longer works. So we took the control box apart and adjusted the springs attached to the hand lever and orange push button. Looked at the wires, couldn't see any obvious issue. The mower's about 4 yrs old, been pretty much problem free. Once it had an issue that, apparently, riding in our car fixed (jiggling it?). My son was mowing when the last battery died -- not sure why it died after just a year (the seller replaced it gratis). I wonder if he hit a rock and blew a circuit. There's something that my kid thinks looks like a relay in the wire box. Maybe it blew when the battery died. Also, just after the battery died, my son shook the mower around some, (though he's 10 and not that big/strong), thinking that might be the issue (like what happened when the jiggling of a car ride seemed to fix a problem). I wonder if he shook something loose this time. Anyone have any ideas? I'll post a picture next time we open the control box. Thanks very much in advance.:biggrin:
