User Manual for Sealey PP100.V2 Automotive Probe

Quick guide from the manual

The Sealey PP100.V2 is an advanced automotive probe designed for diagnostics, including short circuit finding, voltage testing, and component activation. Before use, ensure you are working with 2V-24V DC systems only. Always check vehicle service manuals before disconnecting any electrical sub-systems, especially those sensitive to voltage pulses like airbags or electronic control modules. The tool features a built-in circuit breaker (8A max) to protect against overloads.

Device overview

The probe consists of several key components:

• Probe Tip: Contacts the circuit or component to be tested.
• Work Lights: Illuminate the work area.
• Red/Green Polarity Indicator: Identifies positive (red) or negative (green) circuits.
• LCD Display: Shows voltage, frequency, duty cycle, or resistance.
• Power Switch: Used to activate components with positive or negative battery current.
• Mode Button: Selects between DC voltage, scope, resistance, and audible indicator modes.
• Auxiliary Ground Lead: Used for continuity testing and component activation.

Basic connections and self-test

To connect the tool, unroll the probe cable and connect the red battery clip to the positive terminal and the black clip to the negative terminal of the vehicle battery. Alternatively, use the 12V vehicle accessory socket adaptor. Upon connection, the probe enters voltage mode and the work lights switch on. Perform a quick self-test by pressing the power switch forward (positive voltage, red LED) and rearward (negative voltage, green LED). If the tool fails to operate, press the circuit breaker reset button on the side of the housing.

Operating modes

The tool offers several modes accessible via the Mode Button:

• Voltage: Displays circuit voltage to the nearest 0.1V.
• Scope: Displays maximum/minimum voltage, frequency, and duty cycle. The display automatically adjusts the Y-axis scale.
• Resistance: Measures resistance between the probe tip and the auxiliary ground lead.
• Audible Indicator: Can be toggled on or off by pressing and holding the mode button.

Testing procedures

The probe is versatile for various automotive tasks:

• Voltage and Polarity Test: Contacts a positive circuit (red LED) or negative circuit (green LED).
• Continuity Testing: Use resistance mode. A reading of 0.0Ω indicates continuity.
• Signal Circuit Testing: Use scope mode to test sensors or components where a Diagnostic Trouble Code (DTC) has been detected.
• Activating Components: Connect the auxiliary earth lead to the component's negative terminal and touch the probe to the positive terminal. Use the power switch to energize the component.
• Trailer Lights: Connect to the trailer battery, clip the auxiliary earth to the chassis, and probe the trailer socket contacts while using the power switch.
• Short Circuits: Remove the blown fuse and probe the fuse contacts. The contact that trips the circuit breaker identifies the shorted circuit.

Maintenance

The power switch may deteriorate over time. Replacement switches are available through Sealey stockists. To replace, carefully prise the worn switch from the main casing and press the new one into place until it locks. Always test the switch functionality after replacement.
