Question 2
Fig. 1 is a typical starting system.
- Identify the parts labeled; (i)P (ii)Q (iii)R (iv)S (v)T (vi)U
- List three methods of determining battery terminals.
- State the function of the following in a starting system; (i)Ignition switch; (ii)Starter motor; (iii)Starter relay.
Observation
The expected answers were;
- Parts of a starting system (i) P; battery (ii)Q; fuse (iii)R; ignition switch (iv)S; starter relay (v)T; starter motor (vi)U; earth
- Methods of differentiating battery terminals (i)Size (big; positive, small; negative) (ii)Colour (red; positive, blue/black; negative) (iii)Signs (+; positive, - ; negative)
- Function of starting system parts
The candidates were required to identify six parts of starting system, list three methods of differentiating battery terminals and state the function of three components of a starting system; ignition switch, starter motor, starter relay.
The performance was reported to be below average.
