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)

1ohm or less --> Short to Ground Circuit

1^Mohm 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 ohm and higher than 1^Mohm 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 following 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 1ohm or less. The short to ground circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).
