The MS016A tester shows where the problem is on the car; the MS005A bench finds the exact cause in the removed alternator. The two complement each other.
Modern alternators use electronic regulators, LIN/COM control and start-stop algorithms, making accurate diagnosis hard without professional equipment. MSG Equipment compares the roles of its MS016A tester and MS005A test bench.
The tester works on the vehicle and shows whether the fault lies in the alternator or in the control signal from the car, preventing needless replacement of a good unit. The bench then pinpoints the exact cause in the removed alternator:
- Driving at set speeds, smart regulator control via LIN and CAN
- Support for 12 V and 48 V start-stop alternators with adjustable load
- Ripple, output current and real-time thermal analysis
Recommended workflow: tester on the car, bench after removal, and the bench again to verify after repair.
