I have a Kubota L5740, I received an ERROR-82 / HST NG (swash plate position sensor fault) this morning. I'm not very mechanically inclined, but is this something I could initially troubleshoot myself (e.g. check the wires and the connectors going to the two HST position sensors for damage) without having to get it to the dealership? If so, any diagrams / pictures / videos available? Thanks.
