I recently turned my cocktail into a jamma cab. I have the door lights and CP lights hooked to the +12.. When i put all the bulbs in i get a RINGING noise coming from the switcher.. If i just keep lights in the CP its fine. If i put the lights in the door its fine. If i put ALL the lights in i get a ringing noise...anyone know why??

Im using wedge bulbs #194 14v is that why?? anyone??
 
How many total bulbs? Those 194s take 0.27 amps each. Perhaps you are running more amps than your switcher is rated for or your switcher is getting ready to die.
 
Most switchers only put out one amp at 12v. You're just putting too much load on it with all those lights. Careful, you can damage it like this.

For the lights, you can go to Radio Shack and pick up a 12v transformer - be sure to get one rated for the current you plan to draw. You can run the lights seperate, on AC. Be sure to fuse the line too. I much prefer keeping coin door lights off the switcher - you don't want a simple wiring short in the coin door lamp socket to burn out your power supply.

wire the transformer to the AC with a fuse in between?? kinda like wiring a monitor up???

Also any idea what current i need for 6 bulbs?? Im not that knowlegeable on electric im a tile setter!! :)
 
total of 6 bulbs in cocktails. Switcher is brand new...

Is the switcher rated for at least 1.62 amps for 12v? Sound amplification will often run from the 12v as well so you probably need more.

Kinda - I'd actually put the fuse on the output of the transformer, and add the new transformer in after the line filter and main fuse in the game. The idea here being that if something shorts in the light sockets, it'll blow the fuse and not burn up the transformer.

I'd get a 2A transformer (or 3A), and fuse it at 1.5A. Wire the input of the transformer (120v) to the same place the isolation transformer gets it's input power. On the 12v output of your transformer, put a fuse holder in series, then wire up all your bulbs (in parallel).

ok well i hooked up the 3Amp 12.6v transformer to my AC on my switcher.. This transformer has 3 wires on the other side.. 1 yellow(6.3) 1black (0) and 1 yellow(6.3).

They say if you put the 2 6.3's togetther you get 12.6v.

I ran both 6.3 together to one side of the fuse (with a 1.5 in it) then the other side of the fuse i have my lights plugged to.. The black wire (i am gussing) is ground which i grounded to the cab. The ground for the lights are going to the COM on the switcher.

i am getting nothing... the transformer is getting warm and kinda has a smell to it!!!

any ideas??
 
One yellow is one half of the ac circuit, the other yellow is the other half. It may help you to think of one as neg, and the other pos. Measure your voltage in AC between the two yellows. Should read 12.6Vac. The black wire leave disconnected.
 
the 2 black wires that go from the transformer to the switchers AC.. do i plug both in AC/N? or do i plug 1 in AC/N and 1 in AC/L???

what is AC/N and what is AC/L anyways??
 
N stands for Neutral, and L stands for Load. On home wiring your white wire is the neutral, and the Black is Load, or Hot. Not sure how the AC is wired on your switcher, but for grounding purposes you will want to make sure the hot is hot, and Neutral is Neutral. the wider slot in the wall outlet is the Neutral. So ohm out or check for continuity on your power cord from the wide spade plug, to the switcher to see which is Neutral. Hopefully it wired to the switcher correctly. You'll see markings like N L or H N.

You want the Hot side of your wiring to go directly into the fuse on power supplies.

Most people just plug them in either way since ac travels both directions.

yeah all my wiring to the power cord and switcher are good..all the wires to the jamma, the monitor and evervything else is good


All im tring to do is make this 12V transformer power the 4 CP lights in my cocktail...(which are 4 194 wedge bulbs)

the 12V from switcher is powering my coin door lights so theres nothing wrong there. I just cant run 6 of these bulbs on that 12V line. So thats why im doing this transformer idea to give me another 12V to use....

Im just not following this and i dont know whats wrong...

I have the 12V transformer wired to my AC.. (they are both black primary wires) 1 is going to AC/L and the other is going to AC/N

NOW.. on the other side of the transformer There are 3 wires. 1 yellow (says 6.3v) 1 black wire (says 0) and 1 yellow that says 6.3V

Now i know you have to take the 2 yellows, put them together now i have 12.6v

I then took that wire and hooked it to a fuse holder with a 1.5amp fuse in it.

On the other side of the fuse i hooked a wire that goes to both sets of wedge lights on the CP.

When i trun it on i get nothing... Do i have to have both primary wires goto AC/L? or does one goto AC/L and one goes to AC/N???

You have completely shorted out the transformer. By connecting both ends of the winding together, you're creating a short circuit - you have likely burned out the transformer by now if you have had it on too long.

One yellow wire goes to the fuse then out to the lights. The other yellow wire goes to the other end of the lights. Ignore the black wire, it's the center tap and you're not using it in this application.

It's wired like this. Opps I forgot the fuse on the input side.
