Note the black and white wires coming from the house circuit connected to the power wires on the ballast. Test these with a voltage tester to make sure they're dead, which may require first unscrewing the wire caps, so wear rubber gloves to protect against shock. After verifying the wires ...
When you get a ship test all systems to ensure that they work, and how they work, then use this ship to gain combat experience and as a construction aid and test bed for your new ideas. That’s right. To test out your new ideas. About every modeler I have ever known has his or ...
The test simulates a car that is crossing an intersection being sideswiped by a car running a red light. The sled actually moves at 38.5 mph, but when you do the math, it is equivalent to a 35-mph side impact because of the way the wheels on the sled are angled. Photo courtesy ...
Fluorescent light fixtures sold in hardware stores as of 2010 are a little different than the ones sold a decade ago. Today's fluorescent fixtures feature electronic starting ballasts, while older versions used an independent starter to kick-start the li
