Essential reference information
Begin with the OEM or manufacturer number from the existing starter, alternator, solenoid or relay. Include the complete number and any suffixes. If the label is damaged, send close, well-lit photos from several angles.
Equipment and engine information
- Equipment type, model and serial information when available.
- Engine manufacturer and exact engine model.
- System voltage.
- Any prior part number or supplier cross-reference.
Photos that help
Useful images include the full part, label, mounting face, electrical terminals, connector plugs and pinion or pulley area. Place the part on a neutral background and keep scale and orientation clear.
Why details matter
One equipment family can use different electrical components depending on production range, engine option or regional specification. Sharing complete information supports a more reliable comparison, but final installation should always follow the equipment manufacturer’s service guidance.
