If the machine has any interlock switches by–passed, they must be reconnected for proper troubleshooting and safety. Starting Problems Problem Starter solenoid clicks, but starter will not crank (if solenoid clicks, problem is not in safety interlock system). Possible Causes Battery charge is low. Battery cables are loose or corroded. Battery ground to frame is loose or corroded. Wiring at starter is faulty. Starter solenoid is faulty. Starter mounting bolts are loose or not supplying a sufficient ground for solenoid. Starter is faulty. Nothing happens when start attempt is made. Battery cables are loose or corroded. Battery ground cable to frame is loose or corroded. Battery is dead. Main fuse (20 amp) is open. Wiring to start circuit components is loose, corroded, or damaged (see Chapter 8 – Electrical Diagrams). Neutral switch is out of adjustment or faulty. Ignition switch is faulty.
