Check Short Circuit

• Continuity Check with Chassis Ground

If short to ground circuit occurs as shown in Fig 1, the broken point can be found by performing below Step 2 (Continuity Check Method with Chassis Ground) as shown below.

Specification (Resistance)

1Ω or less --> Short to Ground Circuit

1^MΩ or Higher --> Normal Circuit

1. Disconnect connectors (A), (C) and measure for resistance between connector (A) and Chassis Ground as shown in Fig 2.

   The measured resistance of line 1 and 2 in this example is below 1 Ω and higher than 1^MΩ respectively. Specifically the short to ground circuit is line 1 (Line 2 is normal). To find exact broken point, check the sub line of line 1 as described in the flowing step.

2. Disconnect connector (B), and measure the resistance between connector (A) and chassis ground, and between (B1) and chassis ground as shown in Fig 3.

   The measured resistance between connector (B1) and chassis ground is 1Ω or less. The short to ground circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).
