ANCEL PB100 12v Power Circuit Probe with FX2000 Automotive ABS SRS Transmission Diagnostic Scan Tool

🌍【What is a PB100 Circuit Tester?  】With the PB100 circuit tester, you can check voltage and ground signals in a typical DC circuit.   However, the kicker is that you can also use it to send voltage and ground signals.   It works like a test light that can power circuits or provide a good known ground.   This way, you can effectively test components and circuits without having to break out the old alligator clips and jumper wires.   You can power or ground a circuit directly through the top of the device.
🌍【What can an ANCEL PB100 do?  】In fact, this is a very handy tool for many functional circuit tests.   For example, you can use it to turn on a blower motor.   You can run power window motors, windshield wipers, and even rear window defrosters.   But be careful when turning on anything with a motor, especially something with a motor-driven linkage.
🌍【Voltage indicator】The LED indicator on the front of the unit will show you the battery voltage when it is connected.   You can use it to determine a whole range of things.   You can even do a quick check of the alternator by plugging it in and starting the car.   The voltage should go from about 12.6 volts to 14.0 volts.   This is also useful if you have a situation where a power supply has a large voltage drop, if you notice low voltage on certain branches when checking fuses, etc.
🌍【Circuit Protection】The PB100 has a built-in 8-amp circuit breaker to prevent circuit overload and overheating.   Unlike a normal test lamp, this device can conduct direct battery current into the circuit you touch with it.   Any time you backfeed a circuit, you need to know what you are doing.   The breaker will protect the circuit, but 8 amps is still enough to do a lot of damage with the wrong wire.
🌍【Trailer Wiring】A recurring source of frustration for technicians across the country, especially those who service trailers exposed to road salt or salt water.   The PB100 Circuit Tester features a long 20-foot cable that allows you to make the initial connection directly to the vehicle's battery, while providing easy access to connect the trailer harness at the rear of the vehicle.
