Applications; Electrical Systems - Spectronics Marksman II Série Mode D'emploi

APPLICATIONS

VACUUM LEAKS: Place the hollow air probe on the unit and listen
and watch the LEDs. You can pinpoint the location of vacuum
leaks quickly and easily. Use the hollow air probe or use the
receiver alone.
FIND THAT ENGINE NOISE. The Marksman II will locate those
engine noises and let you find where they are truly coming from.
Ultrasound does not transfer within engine components due to the
directional characteristics of ultrasound. Use the solid contact
probe.
ELECTRICAL SYSTEMS: Separations in high-tension spark plug
wire conductors can be quickly identified from the corona
discharge "snapping" sound emitted. The same applies to arcing
within electrical motors and accessories. Also, listen to connection
points for the "snapping" or "frying bacon" sound; this is a sound a
poor connection makes under electrical load. Circuits are best
tested under operation and full load.
The Marksman II is also great at locating short circuits. Shorts give
off a "frying" or "snapping" sound also. As you are checking for
shorts or connection problems, do not forget to wiggle the
wiring! Those electrical problems will now call out to you. Save
time! Use the hollow air probe or use the receiver alone.
IGNITION SYSTEMS: Listen to today's ignition systems. You can
hear the coils and plugs firing. This is by far the best and quickest
method for diagnosing Coil Over Plug (COP) systems. It also works
great on Distributorless Ignition Systems (DIS). You will hear the
snapping of the plugs firing in the headset. After some experience
testing ignition systems, you will be able to tell if you have a plug or
wire problem by the sound alone. When checking DIS systems,
make sure you listen at both ends of the wire if you can. Use the
solid contact probe or use the receiver alone.
