In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

When you get the call, “The motor won’t start,” you’d best have a logical and systematic plan in place to approach the problem. “Easter egging” just doesn’t work unless you happen to be very lucky!

Transmitter power is not the sole issue, but rather a combination of power and proximity. The lowly cell phone a few inches away may cause more problems than the broadcast transmitter a mile away. The ...

If you are an electronic experimenter who cannot get his circuit working, this is for you. I really feel your pain as it brings back my own unpleasant memories – yes, we have all been there. Here are ...
