My 02 Cat 305CR engine quits when machine bumps hard. Seems it has to do with some kind of relay below left hand control under seat. If I throw a chain next to seat engine stops, if I rap the seat frame by hour meter it stops. Black square relay looking box that seems effected. Parts manual doesn't show what it is. Any ideas?
Give us a clue. Post a photo of what you're looking at. A machine Serial Number would also help ...........
Probably the safety switch attached to the safety lever. You can bypass the relay behind the battery.
I guess we will never know...
