SOURCE: Service Charging System

DONT START THE CAR///IGNITION ON//PRESS THE GAS PEDAL DOWN 3 TIMES SLOWLY//THEN START THE CAR. THAT RESETS THE COMPUTER AND THE CHARGING SYSTEM WARNING LIGHT.

SOURCE: After charging overnight, Roomba only runs about

Reset the Roomba by removing it from the charger, then holding "spot" and "dock" for about twelve seconds. When you let go, the unit will play an ascending series of notes. Then recharge it overnight. If the run time is still short, give Customer Support a call-- be sure to have the Roomba with you when you do.

SOURCE: Controller has no voltage output when connected to fence

You have a dead short to ground somewhere along the fence circuit.Disconnect the leads again,and use a resistance checker to check resistance to ground.(Push a metal rod into the ground to connect one of your leads to,and connect the other lead to the fence.)One or the other fence circuit ends will have a lower resistance to ground.That fence end is closer to the short to ground.Follow that part of the circuit until the resistance to ground is as close to zero as you can find.(taking the ground rod with you as you go)Somewhere in that area you will find your short.

SOURCE: I HAVE DEWALT CHARGER DE9116.ITS OUT PUT VOLTAGE

check output voltage on charger label most chargers are not regulated so if it says 18 volt output it may put out 24 volts but if its putting out 51 volts it may have a short batteries will get warm but not hot replace charger

How to adjust volt. reg. on loboy 154 starter/generator

Sorry but I am not familiar with the machine or the application.

The unit is effectively a dynamo and there is a couple of methods of regulating the output. The movable brush method is crude, inefficient and outdated which leaves a variety of two and three bobbin vibrating electromagnetic types with and without temperature compensation. Until the charge rate exceeds the battery voltage the dynamo would usually be disconnected from the battery, something that could be achieved by manual switching but is commonly the function of the first bobbin of a standard regulator, the dynamo cutout.

The second bobbin is the vibrating voltage regulator which is normally adjusted off load or in the open circuit position; disconnected from the battery and that is achieved by preventing the cutout contacts from closing with a piece of card or similar. The engine speed is raised and the adjustment carried out until the dynamo output voltage is 14.5/15.3. The former adjustment for continuous operation and the latter for short use or operating at night.

It is inevitable there will be variations and it is worth noting if the battery cannot be disconnected from the dynamo an accurate regulator adjustment cannot be made unless the battery is in good health and fully charged - 13.0/13.2 volts after standing for several hours.

How to check alternator output

with engine running you should be able to check alternator output on the battery. put your leads on the positive and negative post and see if it reads more then 12 volts DC. usually charges at 13-13.5 volts

Polorized generator as per manual. went from no output to .2-.4 amps. do I need to rebuild the generator?

Hi, I own a 1976 XLCH1000 and had a similar problem some years ago.
The dynamo must be energized correctly as if not it wouldn't work.
Disconnect the two wire on the dynamo.
Connect a volt meter from the armature connection to the bike frame, negative.
Start the bike up and on a fast tickover there should be 2 to 5 volts present. Momentarily connect, while still monitoring the voltage, a wire link from the field connection to the bikes frame (earth or negative of the battery). The voltage should shoot up to about 25 to 30 volts. If it does you have a good dynamo. If the dynamo is flashed the wrong way around then a negative voltage instead of a possitive voltage will be produced and damage the regulator if it is the electronic type, like on mine.
If the voltage is low, change the brushes and clean the commutator with some wet and dry paper scraping out between the segments to clear the dead carbon deposits. Don't forget the end bearings are "Oilite Bearings" Don't use grease a drop of 20-50 is fine.
Anywhere else in the world, we put voltage on to the field terminal to produce current at the armature, trust the Americans to be different!
Ride safe and loud pipes save lives!
Hope this solves your problem.

2005 silverado z71 5.3. Under normal acceleration all lights will pulse rapidly (at least once a second or faster). Checked alt output at idle- 15.3/15.5 Didnt have a second person to throttle it to check...

Yes,it is,the alternator is charging to much,this can lead to other component failures.Have the alternator changed,not just the regulator in the alternator,if a diode has burned threw,it can,and most likely is,putting out some ac voltage,witch is very bad for the ignition system,and it will put ac voltage in the battery.The pulsing is from ac voltage,not just a dc overcharge.The alternator should be 13.65 volts,to 14.25 volts,at the battery.Most of the time,when there is a pulse,in the lighting,and the alternator is charging around 15 volts,there is ac volts present.so this means,the battery would need to be changed also,to prevent any other problems.I hope this was helpful,and if so,please let us know,thank you.

Honda civic 2001, excessively high voltage 19 to 20 volts ... so something is wrong. Before replacing alt& regulator, what voltage and under what conditions should be on each of the 4 control wires...

never mind testing if when you start the car you are getting them voltages then fit a new alternator and quick before you burn out the ECU ,the regulator has packed up end of story ,change alternator now ,NEW not a scrappy one from scrapyard,and stop try to confuse the issue with something you do not know ,no voltage leaving the alternator should not exceed 14.7v

Produce 24v 300amps of power from alternator w/out car engine

Yes, BUT, you better have a battery, or batteries installed in the system, that add up to 24 volts (I assume this 24 volt alternator has a built-in voltage regulator?)

If there isn't anything to 'tell' the voltage regulator, to just put out the needed voltage to keep 24 volts running smoothly, it will put out way more than that, And BURN up!
