IMPORTANT: In an usual electric circuit, the battery supplies switch which then supplies the electric componentTherefore the switch opens and closes the positive side of the circuitIn circuits controlled by the ECM, the battery supplies the electric component and the ECM works as switch to complete the circuit to the groundTake thi into account when troubleshooting the electrical system
Pay attention to ground wires
Checking for Shorts Between Wires
When checking continuity of wire in circuit, wires should be checked for short circuit as followsMake sure to isolate circuit by unplugging connectorsLet's suppose that the circuit to be checked has RED and BLA CK wireUsing an ohmmeter, measure the resistance between the RED and the BLACK wireThe resistance should be infinite (O.UOth erwise, there is short circuit between both wires We must therefore identify and correct th fa Itvmo200EHl07-l1"
