Power Probe Tip of the Day!

If you need to reset the HOOK's settings for any reason you can:

  1. Press the “SELECT” button in the center of the directional pad.
  2. Wait for the “CIR BREAKR” screen to appear.
  3. Press Up (the “+” symbol) twice or until you reach the “SAVE PREF” screen.

Then, how do you use a power probe?

How to Use a Power Probe

  1. Insert the battery clips into the Power Probe. Put the clamp with the red cord on the positive terminal of your battery and the clamp with the black cord on the negative terminal of your battery or on a ground.
  2. Test polarity by placing the Power Probe tip (the point coming out of the unit) on the circuit.

Subsequently, question is, how do you use the power probe ect3000?

  1. Trace Out a Short Circuit to Chassis Ground.
  2. Tracing Out a Battery Drain or Current Draw.
  3. Isolate your Circuit.
  4. Verify the Short Circuit to Ground.
  5. Verify an Open Circuit.
  6. Short Circuit inside a wire harness.
  7. Reception Distance from 1 inch to 8 inches.

Herein, what's the difference between Power Probe 3 and 4?

The Power Probe 3 is our most popular Circuit Tester. The Power Probe 4 adds more multi-meter functions like Resistance testing, Frequency, AC Voltage, and special test modes like Injector Testing and a Driver Circuit Tester, dramatically increasing the testing capabilities.

What is a Power Probe 3?

The Power Probe 3 is a Digital Voltmeter designed to work on 12-24 Volt sources, with the ability to apply Power and Ground. Using an Auxiliary Ground cable, the user can simultaneously supply Battery Voltage, and ground to test components or to simply test for continuity.

What does P mean on power probe?

First, the voltmeter function on the PP3, is obvious because it is the default test mode of the PP3. So, besides the normal DC voltmeter mode, the PP3 also has “Min” mode, “Max” mode, “P” mode (meaning pulse), and an AC threshold setting.

What is a power probe?

When it comes to diagnosing and testing electronic circuit, Power Probe, Inc. is the leader in manufacturing of electronic circuit testers for automotive industry. Once you connect a Power Probe to the vehicles battery you'll have a Multitude of Testers right at your fingertips.

What can a power probe do?

POWER PROBE BASIC. If there is any ONE electrical tool that gives you the best value in automotive electrical troubleshooting, it's the Power Probe BASIC. It easily activates electrical components, detects circuit polarity and continuity, tests wires for BAD ground connections and resistive Power Feeds.

Is Power Probe 3 computer safe?

Using the meter portion of the powerprobe 3 is perfectly safe, even on CAN bus lines. There is a difference between using a powerprobe to check for the presence of voltage and using it to apply power or ground.

Which side of fuse is hot?

because the answer is, “the hot side is the side that can power the accessory while the fuse is removed.” The hot side turns out to have 14 volts, and the other side for reasons I won't begin to guess at, has about 10 volts.

Which side of a car fuse is positive?

In all vehicles where the chassis is at ground potential (almost all cars) then the fuse should always be on the positive lead and as close to battery as possible. This way if any part of the positive lead after the fuse comes in contact with the grounded body the fuse will blow and protect the circuit.

How do you check a fuse panel?

One place to check is at the connections in the fuse boxes, using a 12-volt test light.
  1. Open the panel on the front of the fuse box by prying back its latch with your hand.
  2. Turn the vehicle's ignition to the “power on” position without starting the engine.

How do you check voltage in a fuse?

To check if the fuse is broken or not while the voltage is applied, we can measure the voltage bitween one fuse's end to ground, and one other end to ground. The voltage should be equal, if not then the fuse is broken or the connection is bad. You can also measure the voltage between fuse's end-to-end voltage.

How do you check fuses in a fuse box?

Checking and changing a fuse can be accomplished without tools.
  1. Find the fuse box.
  2. Lay the rubber mat on the floor in front of the fuse box and stand on it.
  3. Look closely at each fuse.
  4. Identify the circuit affected by the blown fuse.
  5. Turn off house power at the main switch.
