Here at Mecc Alte we only make one kind of product, this gives us a clear focus and vision.
As the world’s leading manufacturer of alternators we recognise our customer’s success is our success. We work hard to ensure we provide pre and post sales support through our dedicated support website.
Winding Resistance Reference Database
The section below provides instant access to comprehensive resistance specifications for all MeccAlte alternator windings. This technical resource has been developed to support service professionals during diagnostic procedures, quality inspections, and maintenance operations.
You can use this database to:
- Verify winding integrity – Compare measured resistance values against factory specifications;
- Diagnose winding faults – Identify open circuits, short circuits, or insulation degradation;
- Validate repair work – Confirm that rewound or replaced coils meet OEM standards;
- Support predictive maintenance – Monitor resistance drift over time to anticipate failures;
- Ensure measurement accuracy – Access reference data under standardized temperature conditions (20°C).
All resistance values listed are derived from MeccAlte's official technical documentation and quality control records, ensuring maximum reliability for field diagnostics and workshop testing.
For optimal accuracy, always perform measurements with the alternator at ambient temperature and compare results against the tolerance ranges provided.
Sales Support Tool
Select alternators for engines, engine kWm for alternators, or custom selections based on specific load sequencing and load type.
This support tool considers motor starting (DOL, SD, VSD, soft start etc), load balance and also non-linear load content (UPS, VSD etc).
