I hope I am not rehashing a previous thread. My tachometer on my Kubota L245DT doesn't work. I disconnected the tach cable from the controller on the engine. Used a drill to verify that the cable and actual tachometer works. Don't know about the hour meter. Started the engine and the controller doesn't move. I take this to mean I have issues with the controller. I believe my next step is to remove the controller. Doesn't look too bad (famous last words). Not sure if oil will seep out when I remove the controller. So, are these controllers serviceable or am I looking for a new or used part? Anyone have a part number?
