About this product
Description
The MS012 COM tester is a professional tool for diagnosing 12V and 24V alternator voltage regulators without requiring an alternator. It precisely simulates key alternator functions, including:
- Rotor winding coil resistance
- Alternator rotor speed
- Alternator load
- Engine control unit signals (for digital and controlled voltage regulators)
This enables an accurate assessment of a voltage regulator’s performance and helps in selecting a compatible replacement.
Key features
- Comprehensive diagnostics – Evaluates voltage regulators under load conditions.
- Easy connectivity – Wire color coding simplifies setup.
- User-friendly operation – Touchscreen interface for convenient control.
- Future-proof – Cost-free software updates.
- Damage protection – Built-in safeguards prevent harm from incorrect connections.
