Hi,If there power out from the ac power pack then the next area to check will be the socket going in to the machines,this leads me to the next point,
try removing the battery ,plug in the ac power pack,
if no result then it will be either the mother board or power socket,

sometimes cheaper to replace it unless you know what your doing,

What makes the on board charger not work an how cah it be tested to see if it is good.


There is a fuse in the charger and another in the chair for the charging circuit. Poor connections to the controller and at the batteries will do it too. If the batteries have been completely discharged, then the onboard charger does not have enough power to start recharging them. If that is the case, use an automotive 12 volt charger that has no automatic charging circuits in it to charge them individually. That means removing both batteries from the chair and connect the charger to one battery at a time. You can test the charger with the batteries disconnected and measuring the voltage on the wires you just took off the batteries. The voltage should be 28 volts or so if the charger is working.

How to test for Electrical power


<p>Be absolutely certain the power is turned off before you begin. To do this, check the clock, timer and oven light, and examine the heating elements on all settings. If any of these components operate, you have power. If a wiring problem has short-circuited one leg of the circuit you may have 110 volts but not 220. This means the oven light, clock, and some heating elements may operate on low, but not on high. It also means you have power and could get a jolt. A jolt from 220 volts can be fatal, use caution!<br /> <p>Once you are confident the oven has no power it is time to establish if the problem is the house wiring or the oven itself. Check the housebreaker or fuse and then test for power where it enters the oven. If there is a 220-volt wall plug, disconnect the fuse or turn the breaker off, then pull the oven away from the wall and pull the plug. Turn the breaker back on and test the wall outlet. Also check the terminal block, located just inside the back of the unit. This is where the main power cord attaches to the oven circuitry.<br /> <p>If your oven is wired directly into the house, the wiring will be connected to the terminal block. Follow the steps above and while the power is off, locate the three-wire terminal block and inspect it for signs of damage, overheating, or melted terminals. Some installations have 4 wires. The 4th wire is a ground for the cabinet. Ensure all wiring is clear and remember <b>not to touch</b> bare wires or terminals. To check the terminals for power, turn the breaker or fuse on briefly and check the terminal block for power across all three legs. Then remove the power at the breaker fuse.<br /> <p>If the terminal block is receiving power, then the problem is within the oven and you will need to isolate the problem using the wiring diagram, found on the back of the oven in a plastic pouch, or on the back or inside the oven near the broiler.<br /> <p>If the terminal block is not receiving power, your house wiring may be the problem. Should this be the case, you will need to call an electrician.<br /> <p><br /> <p>REMEMBER YOU ARE WORKING WITH 220 VOLTS - USE EXTREME CAUTION!!!<br />

2004. Why is the blower motor not receiving power?


The blower motor relay in the auxiliary junction box under the hood is good ? All relays ? only one controls the blower motor ! The electronic automatic temperature control module turns it on by supplying a ground inside the module ! The 30 amp fuse for the blower motor is located in the under hood auxiliary junction box ! At the relay socket test for battery voltage at pins 30 an 86 ,power form 30amp fuse ! The other two pins 85 an 87 ,85 is circuit to the electronic temperature control module . You could test this part of the circuit too , with a test light or volt meter . But if no voltage to the blower motor ,could be the electronic temperature control module is bad !

My cb won't come on or do anything


If you have avolt meter or 12 volt test lamp, try attaching the leads to the plug that plugs into the CB. If there is no voltage or the lamp doesn't come on if you use a test lamp, you may just have a blown fuse. If you are using a cigarette light plug, there may be a fuse in the tip that connects to the center of the lighter jack. If you are getting voltage or the lamp does light, you may have a defective on/off switch. If you blow fuses when the CB is plugged in, you may have a blown polarity protection diode inside of the CB on the main PC Board. If you are not handy soldering, you'll want to leave that job to someone who is. Typically, the Polarity Protection Diode is Black and is mounded very close to where the power wires that come from the plug solder to the PC Board. I hope this helps. :-)

Oven wont come on


If Your oven wont turn on, then You need to be sure that the problem is power related. Try to test Your device for power, then You replace the power switch of the oven. To test the power of the device. Be absolutely certain the power is turned off before you begin. To do this, check the clock, timer and oven light, and examine the heating elements on all settings. If any of these components operate, you have power. If a wiring problem has short-circuited one leg of the circuit you may have 110 volts but not 220. This means the oven light, clock, and some heating elements may operate on low, but not on high. It also means you have power and could get a jolt. A jolt from 220 volts can be fatal, use caution! Once you are confident the oven has no power it is time to establish if the problem is the house wiring or the oven itself. Check the housebreaker or fuse and then test for power where it enters the oven. If there is a 220-volt wall plug, disconnect the fuse or turn the breaker off, then pull the oven away from the wall and pull the plug. Turn the breaker back on and test the wall outlet. Also check the terminal block, located just inside the back of the unit. This is where the main power cord attaches to the oven circuitry. If your oven is wired directly into the house, the wiring will be connected to the terminal block. Follow the steps above and while the power is off, locate the three-wire terminal block and inspect it for signs of damage, overheating, or melted terminals. Some installations have 4 wires. The 4th wire is a ground for the cabinet. Ensure all wiring is clear and remember not to touch bare wires or terminals. To check the terminals for power, turn the breaker or fuse on briefly and check the terminal block for power across all three legs. Then remove the power at the breaker fuse. If the terminal block is receiving power, then the problem is within the oven and you will need to isolate the problem using the wiring diagram, found on the back of the oven in a plastic pouch, or on the back or inside the oven near the broiler. If the terminal block is not receiving power, your house wiring may be the problem. Should this be the case, you will need to call an electrician.
Hope this information helped You.

it could be the power suppy mine went wrong after about 18 months, try ebay there the cheapest. you can test if its the power supply if you know someone with a wii and use there power supply or know how to use a multi meter and check if you have a voltage coming out of the wii plug end. if you dont first try replacing the fuse in the wall plug. hope this helps.

Hp pavilion dv6633 won't start. Lights up, then turns off. HELP!



Hmm.  The most common cause would be a battery that's not recharged.  This could happen if the power supply you plug into the wall has blown an internal fuse.  When plugged in, before turning the laptop on, there should be an indicator light showing that there's power coming to the unit (and another indicating the battery is charging, if it's not already fully charged).  You might try borrowing somebody's compatible power supply to check this (most laptops charge with about 18 volts, DC).  Replacement compatible power supplies can usually be had pretty cheap by checking on Froogle or the like.

Other possibilities are pretty ugly.  Like a BIOS setting got changed to something incompatible with your hardware (pressing F1 or maybe Esc or Del when turning on the unit would get you to the BIOS settings).  Or a memory chip got fried.  Or the CPU chip is overheating because its gotten a little loose from its heatsink.  Or the hard drive has developed a bad sector or corrupted data where the boot sector is located.  Describing exactly what appears on the screen (and any peculiar beeps) during the few seconds its on could help sort out these possibilities, but you'd likely need an in-person geek to fix any of these possibilities.

Best wishes,

Don't have any power except to my lights.


Sounds like a power wire that leads to your starter system may be shorted or broken, or another component may be bad, like a starter or relay. Put 12 volts DC directly to the starter and see if it turns over. If so, go to the power-in side of the starter relay (or solenoid) and see if there is 12vdc with the key on. You can use a volt meter or fluke meter set on volts, or a test light. If power exsists, you will need to check for the power signal that comes from the starter button. It is usually a red, sometimes with a white or black tracer, 18-gauge wire that connects to the relay. This power signal is what activates the relay. If power exsists, you will have to go to the starter switch and test for continuity, and keep tracing back from that point. If you just had the bike apart, its likely you may have forgotten to plug in a component or left a ground wire off somewhere.

Wont turn on


pull the battery and try to power on. if no good test the power adapter with a meter - should give 18-19 volts. if it boots with battery off, power up and put battery back on to charge.

hope this helps
