Electrical Circuit Inspection Procedure

  • Check Open Circuit
  1. Procedures for Open Circuit
    • Continuity Check
    • Voltage Check

      If an open circuit occurs (as seen in [Fig 1]), it can be found by performing Step 2 (Continuity Check Method) or Step  3 (Voltage Check Method) as shown below.

  2. Continuity Check Method
    NOTE: When measuring resistance, lightly shake the wire harness vertically or horizontally.

    Specification (Resistance) 

    1Ω or less → Normal Circuit

    1MΩ or Higher → Open Circuit

    1. Disconnect connectors (A), (C) and measure resistance between connector (A) and (C) as shown in [Fig 2].

      In [Fig 2], the measured resistance of line 1 and 2 are higher than 1MΩ and below 1 Ω respectively. Specifically, the open circuit is line 1. (Line 2 is normal.) To find exact break point, check sub line of line 1 as described in next step.

    2. Disconnect connector (B), and measure the resistance between connector (C) and (B1) and between (B2) and (A) as shown in [Fig 3].

      In this case, the measured resistance between connector (C) and (B1) is higher than 1MΩ and the open circuit is between terminal 1 of connector (C) and terminal 1 of connector (B1).

  3. Voltage Check Method
    1. With each connector still connected, measure the voltage between the chassis ground and terminal 1 of each connectors (A), (B) and (C) as shown in [Fig 4].

      The measured voltage of each connector is 5V, 5V and 0V respectively. So the open circuit is between connector (C) and (B).

  • Check Short Circuit 
    1. How to Test Short to Ground Circuit
      • Continuity Check with Chassis Ground

      If short to ground circuit occurs as shown in [Fig 5], the broken point can be found by performing Step 2 (Continuity Check Method with Chassis Ground) as shown below.

    2. How to Check Continuity (with Chassis Ground)
      NOTE: Lightly shake the wire harness vertically or horizontally when measuring the resistance.

      Specification (Resistance) 

      1Ω or less → Short to Ground Circuit

      1MΩ or Higher → Normal Circuit

      1. Disconnect connectors (A), (C) and measure the resistance between connector (A) and Chassis Ground as shown in [Fig 6].

        The measured resistance of line 1 and 2 in this example is below 1 Ω and higher than 1MΩ respectively. Specifically, the short to ground circuit is on 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 7].

        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).

  • Voltage Drop Test 

    This test checks for voltage drop along a wire, or through a connection or switch.

    1. Connect the positive lead of a voltmeter to the end of the wire (or to the side of the connector or switch) closest to the battery.
    2. Connect the negative lead to the other end of the wire (or the other side of the connector or switch).
    3. Operate the circuit.
    4. The voltmeter will show the difference in voltage between the two points. A difference or drop of more than 0.1 volts (50 mV in 5 V circuits), may indicate a problem. Check the circuit for loose or dirty connections.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
