44. Complete the following statement about front and back probing using the following words?

Words: Cause, Circuits, Connector, Copper, Correct, Damage, Deform, Diagram, Fault, Measurements, Probing, Problem, Safety, Terminals, Wire

When making any checks with a meter, follow all __________ precautions. Try to take all measurements at a

connector. Because the terminals at the connector can be __________ by inserting a meter’s test leads into

the connector, always use the __________ adapter on the ends of the test leads. Adapters are available to match the size of the __________. Using too large of an adapter can __________ the terminals. When measurements are taken at the mating side (front) of a disconnected __________, this is called front probing. When measurements are taken at the back or wire side of a connected connector, this is called back __________. Front probing is the preferred way to take __________. At times, it may be necessary to make direct contact with a wire by piercing through the insulation. Make sure not to damage the __________ and cover the pierced area with electrical tape or clear fingernail polish. This will prevent the __________ wire from corroding.

The key to identifying the exact __________ of the problem is limiting all testing to the components and __________ that could be causing the problem. An understanding of the __________, coupled with an understanding of the circuit, will lead to the __________. A wiring diagram will serve as the map to the problem. Your understanding and knowledge will tell you where you want to go and the wiring __________ will tell you how to get there.

55. Explain what test is being carried out in the image below?

56. Complete the following statement about brushes and holder testing using the following words.

Words: Assembly, Brush, Commutator, Ground, Inspection, Lead, Negative, Springs

Brush __________ begins with an ohmmeter check of the brush holder. Connect one meter __________ to a positive brush and the other lead to a __________ brush. There should be no continuity between them. If there is, replace the __________ holder.

The length of the brushes should be checked, along with the surface of the __________. If the brushes are not within specs, replace the brush or the brush holder __________. The brush holders should also be checked for a short to __________. If they are shorted, they should be replaced. Likewise, if the brush __________ have lost their tension, the spring and brush holder should be replaced.

61. Complete the following statement about inspecting and tightening wiring and cables using the following words

Words: Cause, Checked, Corroded, Damage, Engine, Insulation, Tight

Check the wiring and cables for clean, __________ connections. Loose or dirty connections will __________ excessive voltage drops. Cables can be __________ by battery acid, and contact with __________ parts and other metal surfaces can fray the cable __________. Frayed insulation can cause a dead short that can seriously __________ some of the electrical units of the vehicle.

Cables should also be __________ to make sure they are not undersized or too long.
