Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

Loud sound when it is on


Cooling fans can sometimes be a source of noise, as can loose windings on the transformer. If it is not overheating and funtions normally, the noise is just something to live with. It is not always considered a defect, but you can ask the vendor about it.

I need a lithona lighting power sentry psdl3 wiring diagram


http://www.lithonia.com/SpecSheets.aspx

Lithona has a lot of products and they show the manuals.
Unlike a lot of companies where manuals are not available, as if customers live in the 1980's and still write to companies asking for information.

I don't see your speicific product at Lithona.

A search for 'power sentry' turned up many possible products.
Unlike a lot of sites that just say, 0 results.

Many times, the same product will have more than 1 name or product-number depending on who is selling the product >>> that's how different companies can sell the same product but claim their product line is unique.

You might search the manuals at Lithona and find a similar product under a different name or number.

I have a Schumacker Model SS-51A-PE charger and was charging a boat battery when I heard a medium-to-loud pop. I checked the charger and realized there was no output. It hums quite loudly when plugged in...


Quite simply - the unit has suffered component failure - most likely more than one. Capacitors are the usual source of noisy 'bang' or 'pop' sounds, followed by diodes and bridge rectifiers. If you have some knowledge of electronics, you can attempt repair, but, if none, I suggest leaving possible repairs to someone who does.
The humming sound you hear is the transformer under stress, and, if left connected, it too will die.

The florescent ceiling light in my kitchen takes a long time to turn on after flipping the switch. It is a lithonia light model# 764123


Flourescent Lights use a 'starter' to build up a charge which then jolts them to life. It sounds like your starter is struggling to do the job. The starter is usually located on the side of the light casing and looks like a cylinder which partly protrudes from the case. It twists and comes out and is easily replaced.

No power to lighting ballast ,only lights up on loss of power 277v at emergency ballast


Follow the appropriate wiring exactly. There are about 6-8 different diagrams. Find your lamp type and number of lamps. Locate your ballast type (usually instant these days) Quite often these diagrams show a switch on the power lead going to the operating ballast. If it isn't on a switch be sure to wire it in with the lead to the emergency battery ballast.
