Auto-Electrician's Power Test Probe
This electronic tool will help you diagnose and narrow down electrical problems on all modern and old vehicles including cars, trucks, busses, tractors, etc, etc. The Probe also has long enough cable to ensure you can reach the front and back of the vehicle without reconnecting. It is also equipped with two super bright illumination LED's so you'll never work in the dark again..
Possible tests and Usage: (refer to below picture)
Measuring Polarity:
Check for existence of Positive or Negative Supply to a device.
Ensure the Battery Power Clips (3) are connected to the vehicle's
battery.
Place the Switch (7) in "Measure" mode - middle position marked with
'0'.
Connect the Test Tip (1) to the point of interest. Make sure the Test
Tip makes good connection with the wire or device pin or terminal you are
testing for voltage presence.
Observe the voltage polarity as indicated by the dual color Polarity LED (6).
Red = positive voltage supply is present
at this test point with respect to negative terminal of the vehicle's
battery.
Green = negative voltage supply is
present at this test point with respect to positive terminal of the
vehicle's battery.
No LED light = no voltage is present at the test point.
Inject (supply) Positive power:
Inject (supply) Positive power in to most circuits in order to check the
circuit continuity and/or it's attached device/s operation.
Ensure the Battery Power Clips (3) are connected to the vehicle's
battery.
Place the Switch (7) in "Inject Positive" mode - forward position
marked with 'I'.
At this point the Test Tip of the probe will be energized with positive
voltage and the Polarity Indicator will turn Red.
Connect the Test Tip (1) to the point of interest to inject positive
voltage directly from the battery positive terminal in to the device or
circuit you're testing. Make sure the Test Tip makes good connection with
the wire or device pin or terminal you are energizing. Take care not to
touch the test tip directly to earth/ground/negative supply lines or body.
Inject (supply) Negative power:
Inject (supply) Negative power in to most circuits in order to check the
circuit continuity and it's attached device/s operation.
Ensure the Battery Power Clips (3) are connected to the vehicle's
battery.
Place the Switch (7) in "Inject Negative" mode - backward position
marked with 'II'.
At this point the Test Tip of the probe will be energized with negative
voltage and the Polarity Indicator will turn Green.
Connect the Test Tip (1) to the point of interest to inject negative
voltage directly from the battery negative terminal in to the device or
circuit you're testing. Make sure the Test Tip makes good connection with
the wire or device pin or terminal you are energizing. Take care not to
touch the test tip directly to battery positive supply lines.
Extra Earth Link (2):
The extra Earth Link with the small black crocodile clip can be used to
provide negative supply close to the Test Tip area.
It is connected directly to the battery negative terminal. This extra earth
link can be useful when testing devices which are disconnected from the
vehicle system. To test an disconnected fuel pump use the negative
link and inject-positive as above.
Overload Protection:
The Power Test Probe is internally electronically protected against overload
conditions due to short circuits or reverse current.
When the Power Probe overload protection activates the Overload LED (5)
will illuminate Yellow. The probe can remain in this condition indefinitely
without sustaining damage. To continue normal operation remove the cause of
overload/short etc. etc.
When the overload or short circuit is removed, the probe will automatically
recover and after a short time be ready for work.
Maximum continuous current is 4Amp. Exceeding this will overload and trip
the probe. Trip current is 8Amp maximum.
Warnings:
When injecting power, do not use the probe's Switch (7) to
interrupt current flow as arching over the switch contacts can occur.
Physically remove the Tip from the load before returning the Switch (7)
to "Measure" position - marked with '0'.
Damage to electronic equipment can occur with improper use. Ensure that
injecting power directly in to the system under test will not damage any
electronic components. Most ECU's have negative outputs, thus injecting
positive directly in to them will probably damage them. If you are unsure
what you are testing a safer method is to use a small 5W globe connected
inline between the Tip and the device you're injecting power to.
Do Not use the Probe to test or inject power in to High Voltage
systems! This includes all Primary and Secondary Ignition circuits, HT Leads
etc. etc. Failure to do so will damage the probe in an unique way and any
warrantee will be voided.
Do Not use the Probe on any system that the probe was not designed to
operate including 220v AC or any system with power voltage over 36 volt DC.
Technical Data:
Operating Voltage: 6V to 36V DC
Maximum Current on Inject: 4 Amperes
Maximum Trip Current: 8 Amperes
Illumination Lights: 2 Super bright LED's
Power Cable length: 5m
