Better Troubleshooting

[brother]

Ive seen some 'not' so good trouble shooting, and this I was just suprised to see. Seen a guy trouble shooting the low voltage transformer (30 volts AC) where the apparently either a relay or a wire had shorted and had the whole line stuck where the low voltage switches would not turn the lights on, or off (depending on what the position the lights were in).

What was happening was they were using the 'new transformer' and seeing if there was still a load on it each time they supposely would 'disconnect' a portion of the run until the 'arc was gone.

Wouldnt a megger worked in this scenerio, maybe not the high voltage level we use, but their adjustable. What do you think??

is this a megger or a circuit tracer?? Im talking about a megger.

Having trouble with my vision of this from the comfy chair.

Any ohmmeter and half a brain.... A megger in the hands of whoever was doing that might be more harm than good.

Anyway they had the right track on the basic idea of the tactic, but lacked common sense enough to use something that could do more damage to the circuit by shorting it like that.
