My bobcat sat for a month or so and now the ACS light is on. It worked just fine last time I ran it. I do not get an error message though. The battery was completely dead when I tried to start recently, I charged the battery, then disconnected it, but no change. Sounds like this happens a lot and nobody seems to have an answer except to take it in to the dealer. Just curious why I dod not get an error message or code. ANy ideas from anyone?
