Initial Inspection and Diagnostic Overview
How to Troubleshoot Circuits at the ECMSpecial Tools Required
- Digital multimeter KS-AHM-32-00:3 (1) or a commercially available digital multimeter
- Backprobe Set 07SAZ-001000A (2)
1. Connect the backprobe adapters (A) to the stacking patch cords (B), and connect the cords to a multimeter (C).
2. Using the wire insulation as a guide for the contoured tip of the backprobe adapter, gently slide the tip into the connector from the wire side until it touches the end of the wire terminal.
3. If you cannot get to the wire side of the connector or the wire side is sealed (A), disconnect the connector and touch the tester probe (B) to terminals (C) from the terminal side. Do not force the probe into the connector.
NOTE: Do not puncture the insulation on a wire. Punctures can cause poor or intermittent electrical connections.
