A small, wireless transmitter may simplify electrical diagnosis in your service department. Here's why this method may become a more-common test technique.
Voltage is electrical pressure; current is electrical volume. Measuring these values with the appropriate meter is the foundation of effective electrical diagnosis.
However, field experience has shown that poor access to electrical connections and components often discourages — or completely thwarts — these vital measurements.
The result is costly guesswork and mistakes. Simply put, the harder it is to reach, the less likely it is to be tested and tested thoroughly.
Equipping a meter with extra-long test leads is one way to access hard-to-reach electrical connections and components.
A regular supplier may have these products. If not, then one potential source is Automotive Electronics Services.
This company has been making custom leads for me for more than 20 years. Thanks to these extra-long leads,
I have been able to make many electrical measurements safely from the driver's seat — especially during road tests.
Another option is a meter with a wireless, remote display. Here, a technician connects the meter to the circuit or component — but leaves the meter resting in place near the test point's location.
Then the meter transmits its measurements to a detachable, palm-size display. A tech can carry this remote display to the driver's seat or some other spot in or near the vehicle.
