Using a voltage pen with the process described in this article, you can more definitively determine where a failure is in a circuit, as compared to a static method of “ohming out” components. THIS BLOG IS INTENDED FOR APPLIANCE TECHNICIANS ONLY. ALWAYS USE APPROPRIATE SAFETY PRECAUTIONS WHEN WORKING WITH ELECTRICITY. Brute Force Voltage Pen Diagnostics […]
Instead of just “ohming” out components, get the “real” story by performing live brute-force point-to-point troubleshooting and force the failure to reveal itself. Please note that this guide is for qualified technicians familiar with the hazards of testing live mains circuits, and that employ adequate safety procedures. THIS BLOG IS INTENDED FOR APPLIANCE TECHNICIANS ONLY. […]

LoZ meters are valuable tools for identifying ghost voltages and compromised voltage sources that exhibit high impedance upstream. When troubleshooting AC mains circuits, it is generally recommended to use the LoZ mode. This mode introduces a load at the test point, which proves advantageous because the circuits being tested are typically of low impedance compared […]
