Question

11.) the starter motor in the illustrated circuit cranks the engine slower than normal. a load test indicates that the battery is good. which of these could be the cause? (a) a blown fuse at w (b) an open relay coil at x (c) high resistance at y (d) a short to ground at z

Explanation:

Step1: Analyze a blown fuse

A blown fuse at W (A) would prevent current flow and likely stop the starter from working at all rather than just making it slow.

Step2: Analyze an open relay coil

An open relay - coil at X (B) would also disrupt the circuit and may prevent the starter from functioning, not just cause it to be slow.

Step3: Analyze high resistance

High resistance at Y (C) would impede the flow of current. According to Ohm's law \(V = IR\), when resistance \(R\) increases and voltage \(V\) is constant, current \(I\) decreases. A lower - than - normal current to the starter motor can cause it to crank the engine slower than normal.

Step4: Analyze short to ground

A short to ground at Z (D) can cause electrical problems, but it is more likely to cause erratic behavior or a non - functioning starter rather than just a slow cranking.

Answer:

C. High resistance at Y
