Take Control of BS6 Two-Wheeler Diagnostics with the M601 Scanner
Relays are critical electromagnetic switches that control high-current components—like starter motors, fuel injectors, headlights, and radiator fans—using low-current trigger signals from the ECU or ignition switch. When a headlight fails to turn on, a fuel pump won’t prime, or an engine won’t crank, a faulty relay is often the culprit.
Traditionally, testing a relay required setting up manual wiring jigs, connecting an external power supply to trigger the coil, and using a digital multimeter to measure contact resistance. This process is slow, tedious, and prone to error.
The Relay Tester with Voltage Digital Meter automates this entire procedure into a single handheld click.
By plugging a 12V relay into the tester and connecting the alligator clamps to the vehicle’s battery, the device automatically triggers the relay coil multiple times. It measures contact resistance, mechanical latency, and coil health under load, giving you an instant, foolproof diagnosis.
Key Features & Benefits:
- Integrated Digital Voltmeter: Monitors and displays the vehicle’s battery voltage. This helps identify if an electrical malfunction is caused by a drained battery (e.g., drops below 10.5V under load) or a failed relay.
- Rapid Cycle Testing: The device automatically runs cyclic switching tests (usually 10 consecutive pulses) to detect intermittent sticking or high contact resistance that causes intermittent starting faults.
- Safe and Protected Operation: Built-in protection circuitry prevents damage to the tool, the vehicle, or the relay in case of reverse connection (swapping red and black clamps) or short circuits.
- Insulated Heavy-Duty Clamps: Supplied with a 1-meter long cable and high-tension rubber-insulated alligator clips that connect securely to battery terminals.
- Handheld Workshop Grade Housing: Lightweight and compact casing built from impact-resistant plastic designed to withstand drops, oil spills, and daily workshop wear.
