12V Switched Fused DC Motor Circuit Simulation - Switch Closed Multimeter Test

This document is a screenshot of a simple simulated electrical circuit (drawn in circuit-simulation software such as Multisim) rather than a factory wiring diagram. It shows a basic series circuit representing a switched, fused DC motor circuit like those found in a vehicle. The circuit consists of: a 12-volt DC source labeled V2 (12 V); a switch labeled J1 with the annotation 'Key = A' (meaning the 'A' key toggles the switch in the simulator); a fuse labeled U1 rated at 15_AMP; a load labeled S1, identified as DC_MOTOR_ARMATURE; and a multimeter instrument labeled XMM1 connected across the switch J1. Circuit nodes/nets are numbered 1, 2, 3, and 4. The filename 'SWTCH CLSD.jpg' and companion files in the album (AMP, FUSE, SRCVLT, SWTCH OP, TestVLT2, tstvlt1) suggest this is one frame of a training/demonstration series measuring voltage across a switch in closed versus open states. A reader can learn the basic topology of a fused, switched 12 V motor circuit and where a meter is placed to test voltage drop across the switch. The document contains no vehicle-specific information, part numbers, wire colors, or year/model applicability.
