Short Circuit Test

• Continuity Check with Chassis Ground

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

Specification (Resistance) 

1Ω or less → Short to Ground Circuit

1MΩ or Higher → Normal Circuit

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

   If the measured resistances in lines 1 and 2 are "below 1 Ω" and "over 1 MΩ" respectively, line 1 has an open circuit. (Line 2 is normal.) To find the exact broken point, check the sub line of line 1 as described in the next step.

2. Disconnect connector (B), and measure the resistances 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).
