Why does the voltage drop to battry volts when i put the gear lever in drive?


the voltage should remain at 14.5 volts at all engine speeds above idle 13.9 volts at idle indicates that the alternator is charging but not at set voltage
head lights are the biggest drain that affects charge rate rate and it it maintains and from you description that is not a problem
when you select a gear it indicates a heavy drain which is a high resistance or a dead short in that circuit that is taking out more power than the alternator is charging
There there is nothing in the gear selection that draws such power
the other thing is that when selection a gear the engine rpm is tool low and the alternator stops charging
for auto vehicles , the idle rpm should be at 800-900 rpm dropping to 750-800 in drive

I have AR-5618,I change the drum the copy is still fainting,but if I put toner on developer the copy we come out well,what can I do?


Could be the high voltage power board
see page 6-2 section 3 labelled developing bias voltage check
http://en.calameo.com/read/0029008186484bf5ab7fd

I do not know this model of photocopier but from the basic theory of how laser printing works the high voltage of 525v puts an electrostatic charge on the developer. If the electro static charge voltage is lower than expected the toner may not be attracted onto the developer. I suggest the high voltage power supply as a possible failure point or the electrolytic capacitors in the high power supply board
but
BE CAREFUL as high voltage = Demise of life if electrocuted
may need a qualified service technician to check it

Batteries were not holding a charge so I replaced them. Brand new batteries and it is still not holding a charge long enough. I lose one green light within minutes of turning it on after charging all...


Sounds like you have a bad charger. If you have an on board charger, plug it in to the wall and test the voltage at the charger port at the front of the joystick between pins 1 and 2 (the two eyes of a happy face). If you get between 26 and 28 volts and the voltage rises as you charge, then the on-board charger is OK. If not check the AC cord and connections to the charger, including the lego black block and/or connection of the charger at the controller. The type of connection depends on year and serial number.
If you have an off -board charger plugged into the front of the joystick, check your voltage directly at the batteries with the seat flipped back. With the off-board charger plugged into the front of the joystick measure the voltage being applied to the batteries at the large black 2 pin plug coming from the controller to the batteries. When you take this measurement leave the plug connected and put your digital voltmeter probes in the connector at the back (non-contact side). With the charger on, voltage should read between 26 and 28 Volts or come to that voltage after some time.
On board chargers run about $200 and off board chargers around $300.
Invest in a good AC cord if yours is questionable. For $8, I have fixed many of these chargers with a new AC cord from Radio Shack. Hope this helps.

Battery keeps dying,starts immedetily when you hook jumper cables to it,could this be the alternator?


it could well be that if its not charging the car battery up,,or it could be you have a dud battery that just wont hold its charge any more

Power cord will not charge my laptop


The adaptor is dead. DO NOT open this, there are high voltages inside. Take it to a repair centre or buy a new adaptor.

When headlights are turned on there is an obvious loss of juice, engine labors and clock goes dim


Check alternator voltage charging should be 13.4 to 14.3, if lower bad alternator. If you have an ohmmeter set to dc voltage put on bat cables read voltage, turn lights & heater blower on high, read voltage, if below specs alternator bad

Recently having problems with my 2000 Fatty not holding charge. What should stator be putting out on voltage meter? Voltage meter climbs as rpms go up, I would presume that this indicates stator ok? Bike...


First, take your battery somewhere and have it load tested. Fat Boys are tough on batteries as the battery sits in the "horseshoe" oil tank and is subjected to high temperatures due to the hot oil in the tank. Battery life is typically two years although I've seen some go longer and some not last that long. Have the battery tested before you start spending money.

To check the stator, you unplug the regulator at the engine case. Down inside the plug you'll see some electrical connectors. Connect a DVOM (digital volt ohm meter) to these connectors (one lead to eac pin) and put the meter in the 50 volt or higher range AC voltage. This is important that your meter be set to measure AC voltage because at this point, the voltage is indeed an Alternating Current voltage coming out of your alternator. Start the engine and bring it to a high idle. You should be reading over 20 volts AC. The book says that you should read 12-18 volts per 1000 engine RPM. If your engine is turning 2000 rpm, your meter should read 24-36 volts AC.

To test the regulator, first charge your battery to a full charge. Then connect your DVOM across the battery, red to positive, black to negative. Put the meter in the 20 volt DC range. Start the bike and bring it to a high idle. The voltage will start at somewhere around 12.5 volts and climb to about 14.5-15 volts. This would indicate that the regulator MAY be alright.

Now, have you changed any of the lights on your Fat Boy? I've seen people change and add lights to the point where their alternator could no longer put out the current necessary to handle the load. If this is the case, you may need a higher out charging system.

I don't know where you're located but $260 seems quite high for a voltage regulator.

Power cord is plugged in, but the computer won't turn on


That could be. If your battery is dead and the adapter won't charge it, you can't turn it on.
Test the adapter with a multi-meter to see if it is putting out the correct voltage which should be 18 volts, if I remember correctly.

You turn on the tv then it turns off right away with no picture displayed could probably used new screen too


The repair of this unit will be determined by the status of the high voltage on initial power up. You need to do a few tests in order to narrow down what the high voltage is doing. You will need someone to assist you.

Unplug the AC cord. Remove the rear lower cover from the tv. Make sure the room is quiet. Put your ear inside the tv being careful not to touch anything metal, although most metal objects are ground. Next, have someone insert the cord into the AC outlet while listening very carefully. What you are supposed to hear is a click which is a relay and high voltage snap up. If you do not hear a swishing sound, which is the sound of high voltage have someone press the power button on the front while you are still listening. If you hear the swishing high voltage sound come on, it will come on and stay on, or collapse. Repeat the test, unplug the cord and plug in the cord to confirm the high voltage is coming on and staying on or coming on and going into collapse.

If the high voltage does not come up at all it means that there is a basic high voltage power supply problem and an experienced technician needs to guide you through a high level repair which is above the scope of this discussion. You may want to contact a skilled technician.

If the high voltage comes up and collapses right away, which is the most common fault, it means that the unit is entering the protection mode. The protection mode is most commonly caused by convergence or vertical sweep system on that model and big screens in general. These repairs can possibly be done by consumers with basic electronics knowledge. If you want to repond with test results we can supply more information on repairing the convergence or the vertical sweep system.

If the high voltage stays up then the likely fault is a power supply problem is muting both the video and the audio causing the unit to go into protect. Consult a service manual, track power flow though out the unit to determine which circuit is impaired.

It sounds like your charging system may be causing the problem. The voltage may be too high or the stereo may be too sensitive to high voltage. You need to connect a voltmeter to your system to make sure it's not charging over 14.5v. A normal charging system wii charge at 13.5-13.8v.

 

Have someone connect a digital multimeter to the B+ and ground wires of the head unit. Have a passenger monitor the voltage while driving. If the head unit cuts out at the same voltage each time and the voltage isn't excessive, the head unit needs to be repaired. If the voltage goes up above ~14.5v, the charging system needs to be checked.
