Question about System Power Supplies

Idle problems I have a yamaha 650 V-Star Custom. I am having trouble setting my idle above 1000rpms. The bike cuts off. The only thing I can do to keep it from cutting off is to keep the choke lever pulled out about 1/4 of the way. I have turned the idle know to the right as far as I could. I have changed my spark plugs, my oil, oil filter and air filter. With no sucess. Any ideas besides taking my carborators off?

Re: idle problems

If the bike has been sitting over the winter or a few monts , the carburator is probably varnished up. Need to take it to a shop and get it cleaned and tuned. I usually take my carb off my dirt bike after it sits all winter and clean all the needle valves and then tune it. Good luck

Re: idle problems

You should have a idle adjustment knob under the gas tank, left side.

Re: idle problems

Hmmm... this doesn't sound like a problem that belongs here... By "cuts off" do you mean stop running, or misfire? Carb. problems often are the result of the bike having set for many months or a year or two with old gas, which can result in a varnishing like of the fuel in the carburetors, which can clogg small passage ways, and subsequent no-idle, or other poor fuel delivery. Problems such as this require repair by knowledgeable mechanics. Other things which can upset correct fuel/air mixture are modifications such different exhaust system, air cleaner change, camshaft- any mod of these can require some retuning.

I have a 2005 Yamaha YFZ600 with only 3500 miles on it. The bike won't start and if I do get it started once I give it gas it stalls out. I've change the gas filter and clean the carburetors and floats....

Now that you brought up the sound phenomenon, it is not a normal procedure for any fuel pump. To me it seems that the fuel pump is faulty and there is no fuel going to the carb. And that is why it does not start. And when you try too hard it does start with whatever you have and then goes off when you rev it up. So open up the fuel pump and check its bearings etc. The noise means that the bearings are not up to the mark.

How to connect a maglock to a fire relay? I have to insure that maglock controlled doors release when the fire alarm is activated. I have a Ccure Istar panel and I think a apc pwr supply

On most fire alarm panels there are normally open and normally closed relays that will change state in the event of a fire. The negative power line can be ran through these relays to allow the maglock to be powered down in the event of a fire. The relay on the fire panel may need to be programmed to do this or it may come programmed by default which is usually the case. Hope this helps.

Power cord cuts in and out

There are two places the trouble can be happening, at the adapter plug or at the power jack in the laptop. To determine which one is causing the power loss, hold the plug in the computer steady with your fingers while you wiggle the adapter cable. (If you have access to a voltmeter you can measure the voltage at the plug while you wiggle the cable to see if remains steady.)

If the charge light flickers it's the adapter cord that's bad. Because the wire flexes so much at the plug, it can break inside the insulation and cause the power loss. You either need to replace the adapter or repair it by cutting off the bad end and installing a new plug.

If the charge light remains on with the plug held steady but flickers when you wiggle the plug itself, the trouble is on the main board in the computer. The solder connections at the power jack have broken from the plug flexing and need to be repaired. This involves opening up the computer and getting at the solder side of the main board. It's tedious but relatively simple. If you are not experienced with soldering on small electronics, leave this to a professional shop.

My monitor turns itself on and off with no prompting

Go into the control panel and check the system settings. You might have it set to turn the monitor off after a low number of seconds of use. If you have it set for 30 seconds, if you don't use the keyboard or mouse for 30 seconds, the monitor will shut off. When you start to use it again, it will come back on.

Dell Dim 8400 Issues

Hi Steve,
The problem that you are facing is most likely because of bad harddrive. As you have already replaced the RAM. To confim the same , run a diagnostics on the Hardrive. You can run the same in two ways .

Check if have the utilitu partision still left on the hardrive
1. Tap on the F12 key 5 - 6 times when you see the Dell splash screen , before windows starts to load.
2. Select Hardrive diagnostics or IDE diagnostics

If the above is no there , look for the dell Rescouce cd
1. Boot the system using the dell Resource Cd.
2. Select 32 bit diagnostics from the menu
3. Run a custom test on the hdd.

If the hardrive fails , replace the same, otherwise try swaping it connector cable with the optical cable.

Computer cuts off

Simply replace the power supply with a working one to confirm power supply problem. If the power supply is the problem than ask your grandson to open the casing of the power supply unit and see if there are bulgy signs on the top of the capacitors, and replace them with the specific ones. This problems may arise because of defective components, it might be best to leave it to the technicians to do the repair. Hope it helps.
