Digital circuit tester

" indicates a continuity of electric-

ity which means a closed circuit at the

respective switch position.

When checking the peak voltage, do not

touch any of the connections of the digital

tester lead wires.

• When checking the condition of the

ignition system, it is useful to know the

peak voltage.

• Cranking speed is dependant on many

factors (e.g., fouled or weak spark

plugs, a weak battery). If one of three is

defective, the peak voltage will be

lower than specification.

• If the peak voltage measurement is not

within specification, the engine will not

operate properly.

The peak voltage adapter should be used

with the digital circuit tester.
