The ET8626 is a professional battery and charging-system tester designed for fast, accurate assessment of all 12V automotive lead acid cranking batteries - including modern stop-start types, and for evaluating 12V and 24V alternator and starting system performance. This tester delivers clear, reliable diagnostics in seconds, and the built-in thermal printer allows you to produce instant test reports for customer records or workshop documentation.

• Compatible With All Major Battery Standards - accurately tests batteries across all common industry standards, ensuring reliable results whether you're working with automotive, commercial, marine, or deep cycle 12V batteries.
• High Load Voltage Testing for 12V & 24V Systems - maximum load voltage tests on both 12 volt and 24 volt electrical systems, making it suitable for cars, trucks, machinery, and mixed fleet applications.
• Built In Short Circuit & Reverse Polarity Protection - integrated safety features to prevent damage to the tester and the battery, even if connections are made incorrectly.
• Wide 100–2,000 CCA Testing Range - enabling accurate assessments of everything from small passenger batteries to heavy duty commercial units.

Remove guesswork from modern vehicle diagnostics by putting every OBDII circuit at your fingertips. This professional breakout box gives technicians instant access to every OBDII circuit for faster fault finding, ECU testing, and network diagnostics. Whether you're diagnosing communication faults, testing CAN bus systems, performing ECU bench testing, or verifying vehicle power and ground circuits, the ET3142 provides the visibility and control that standard scan tools simply can't offer.

Featuring a built-in LCD display with real-time True RMS voltage monitoring across all 16 OBD-II pins, the ET3142 allows technicians to instantly identify power supply issues, ground faults, CAN communication activity, and wiring problems without repeatedly probing connectors. Dynamic signal detection, audible voltage alarms, and ground status indicators help reduce diagnostic time and improve accuracy.

The integrated 120 CAN termination switches make the ET3142 an invaluable tool for ECU bench testing and module diagnostics. By providing proper CAN network termination, technicians can test modules off the vehicle with improved signal integrity and confidence. Compatible with both 12V and 24V systems, it is suitable for passenger vehicles, trucks, buses, and commercial equipment.

• Real Time VRMS Voltage Monitoring - displays real time True RMS voltage on all 16 OBDII pins
• Built In CAN Termination for Bench & ECU Testing - an onboard 120 ohm CAN termination switch is ideal for situations where termination is missing such as single ECU or small bench networks.
• Intelligent Voltage Protection & Audible Alarm System - reverse polarity protection, automatic alarms for over voltage and under voltage conditions, and support for currents up to 2A, ensures that both the vehicle and diagnostic tools stay protected during testing.

The Power Probe 3 with PowerFlowª Technology is built for technicians who need faster, more confident electrical diagnostics on 12V and 24V vehicle systems. It combines the trusted functionality of the Power Probe 3 with advanced circuit-loading capability, allowing technicians to measure voltage, apply battery power or ground, check resistance, activate components, and verify circuit integrity under real-world load conditions. With PowerFlowª, hidden faults such as high resistance, corrosion, weak grounds, and excessive voltage drop can be exposed quickly Ñ helping reduce guesswork, avoid unnecessary parts replacement, and speed up every diagnostic job.

• PowerFlowª Circuit Loading Technology - Actively load positive or negative circuits to test wiring under real operating conditions. PowerFlowª helps reveal voltage drop, high resistance, weak grounds, corrosion, damaged wiring, and poor connections that may not appear during standard no-load voltage testing.
• Apply Battery Power or Ground - Quickly supply 12V or 24V battery power or ground directly to components for fast functional testing. Ideal for checking motors, lights, relays and other electrical components.
• Resistance Measurement up to 25 k - Measure resistance to help verify component specifications, identify poor connections, and locate high-resistance faults caused by corrosion, damaged wiring, or component degradation.
• 10A Solid-State Circuit Breaker - The integrated 10-amp solid-state circuit breaker provides protection while supporting higher-load component testing. It allows technicians to power demanding loads with added confidence and automatic reset protection.
• Built-In Electronic Latch Function - Apply continuous power or ground without holding the actuator switch. This is especially useful for extended component activation, dynamic troubleshooting, and hands free testing.
• Quick-Connect Ground Lead - The ground connection uses a 4mm banana jack for improved flexibility and reliability. It allows the use of extensions, adapters, and test leads while maintaining a secure ground connection.
