WebParasitic draw can be tested with a multimeter to measure current in a wire through which no current is expected to flow. The multimeter is set to the ohm setting and two probes are placed on each end of the wire being tested. If the resistance is greater than zero ohms, current will flow through the wire. WebThe same is true for induced signals inside a harness, especially a harness that has been modified. Always look for “previous work” and damaged wiring or connections. Maybe it has corrosion or broken wires that affect all or part of the electrical system. Sometimes that is the cause of the parasitic draw and the diagnosis is done.
