Should I Make a Bunch of Different Test Lights to Load Circuits?

There seems to be a current trend, where a tech feels it is necessary to carry around a bunch of different homemade test lights. Each one carrying a different amount of current.
This is done in order to load the circuit, to test wiring integrity, when an open in a component is found, or because they may not trust their voltmeter and what it is telling them (unfortunatley most techs fall in this catagory).
While I like the idea, and will use my test light in this way, I don't need a bunch of different test lights, that carry varying amounts of current, to be 100% accurate on my calls. Just my 200ma incandescent and my 13 ma LED is all I need. Learn to trust your meter, combine voltage measurements with current measurements and use your test light at times to back it up. Are there times that having that high current bulb can help you? Of course! Again, my arguement is to those who would say it is NECESSARY to be 100% accurate. Helpful is one thing, necessary is another.

On ScannerDanner Premium I will bring you right into my classroom at Rosedale Technical College. You will find page for page lectures taken right from my book as well as exclusive classroom type case studies. What is so special about these classroom case studies? I pull live problem vehicles directly into my classroom and we troubleshoot them in real time, using and applying the theory and testing procedures we learn during the classroom lectures. There is no better on-line training of how to troubleshoot automotive electrical and electronics systems anywhere!
