Re-inspect harness routing after reassembly to verify there are no pinched wires or tension points that could cause intermittent faults during operation.
The glossary of terms included in this appendix consolidates key terminology used throughout the Montgomery Ward Gil1580j service materials. Terms related to engine and electrical systems, such as carburetor idle speed, ignition timing, compression ratio, and spark plug gap, should be understood in context with the associated diagrams and specifications. Maintenance terms like torque, clearance, and lubrication correspond to actions you perform during routine service or when addressing wear-related symptoms. Safety-related terms such as lockout-tagout, grounded, and isolation must be followed rigorously to protect yourself and others during repair procedures. Familiarize yourself with common measurement units, including inch-pound and Newton-meter torque values, to avoid misinterpretation of specifications. A solid grasp of the glossary will accelerate diagnostics and empower you to communicate clearly with technicians or support staff when seeking guidance. Keep a copy of this glossary accessible near your workbench for quick reference during field or shop maintenance tasks.
