A cranking current test on a diesel engine indicates low current draw.Which of the following faults would NOT be responsible for low current draw?
A) partially discharged batteries
B) low viscosity engine oil
C) high resistance in the ground circuit
D) high resistance in the insulated circuit
Low Current Draw
The condition of an electrical device consuming a relatively small amount of electrical current.
Viscosity
The sheer resistance of a liquid often used to mean oil thickness or resistance to flow.
Ground Circuit
An electrical circuit that uses the earth as a part of its conductive path, enhancing safety by preventing electric shock.
- Pinpoint and fix common difficulties in the operation of diesel engine starting systems.
- Learn about the implications of resistance in starter motor circuits and how to effectively diagnose these problems.

Final Answer :
B
Explanation :
Low viscosity engine oil would not be responsible for low current draw during a cranking current test on a diesel engine. In fact, lower viscosity oil would likely reduce the resistance to engine cranking, potentially reducing the current draw needed to crank the engine. High resistance in electrical circuits or partially discharged batteries would increase the current draw, while low viscosity oil would have the opposite effect.
