Good Video 👍 I would like to see a video performing a megger test or insulation test on wires and the reading we should get, that's another tool used a lot when troubleshooting wires. Thanks

Absolutely. You mean using a megger to trace leaks to ground or to test static wick bonds?

@@AvionicsEducation both are perfect, the more info out there the better. Sometimes we use the megger to ck the coax on the Radio Altimeters, or to ck wires insulation for leaks.

11:40 For Rule #4 I have a application specific suggestion. I do a lot of shutdown current testing for automotive (dead battery in the morning). I realized that using a DMM with a 10A port for testing wasn't precise enough to test individual fuses to see which circuit was pulling 8-10 mA. The problem was that it flowed close to 1.8A in the beginning of the shut down then down to 9.8 mA after. Yet on the display it would show 0.00A, the fuse of the little 400 mA of the mA port had blown of the DMM. I found the UNI-T UT60S DMM that had a mA function in the 10A port, thereby allowing the user no need open the circuit to use the mA functionality. You could test the shutdown current, in real testing I got down to 2.8 mA which is absurdly high sensitivity from the 10A port. Its not the brand of meter pre se, rather the way the ports where configured for testing that makes it useful.

When they detect an open or broken wire, do they replace it with another or join it using splices?

Depends on the condition of the existing wire and what it is used for. If it is a power wire or extensively damaged then it will be replaced. If it is a signal or low voltage wire (i.e. audio channel) and is in otherwise good shape then it can be environmentally spliced. Obviously replacement is the ideal route but time, possibility of maintenance-induced-failure and access restraints may prohibit an entire replacement or may defer it until a later time.

Do you recommend a particular multimeter for avionics tech students?

Great question. Well nobody sponsors my videos so I can only respond based on personal preference. for the last 40 years I still have my first meter from 1989 when I started working as an Avionics tech at America West Airline. I was going to be a line support technician meaning I was looking for a meter that can stay in a tool bag. I needed to be water resistant and be shock proof. Calibration was not that critical because the company would provide calibrated tools for RTS. Therefore I have only purchased Fluke meters for cost and longevity. They served well for my avionics school also. Also don't be drawn to shiny things. Meaning only buy one with the simple functions. Get one with the features you need.
