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.

My charger on Rascal 600 does not charge. After checking all the common reasons without any luck I remove the charger and could not measure any voltage output. My Dealer sezs the charger won't work without...


Most chargers are 3 pin. Plus and minus charging voltage to the
batteries and a third pin monitors the actual battery voltage, so
that the automatic charger can turn itself off once the batteries
are fully charged. As Brad has mentioned, the connection
from the charger has to be made for the charger to produce
a voltage at those pins. The best way to see if it is charging
is to remove the seat and measure across both batteries..
assuming it's a 24volt system like most. Charging voltage
can be as high as 28volts across the positive of one 12volt
battery (connected in series to the other 12v battery) and the
negative of the other battery. You can monitor the charging
voltage across the batteries with a digital volt meter.

My 2 year 9400 charging station does not make good charge conection with 9400 remote. red charge light does not come on untill you giggle many times in cradle. checked battery connection and power off and...


Hi,thanks for posting your Question.. Most times, when you keep using a TSU9400 remote which needs to be charged, and you always remove the charger from it and fix back when you need to charge it again..It makes the mouth of the port where you insert the pin charger to go weaker every time..
So in the issues you might need to replace the port where you insert the charger into..Or you can test out another charger first to confirm if it will charge properly..
If it does not charge,that means you might need to contact your repair canter in your area for help.
It might also be a problem of firmware update too.. You can use the link below to know more about firmware update..

I have a power wheel price fisher charger and i like tu use it to charge a peg perego battery i have power wheels fisher-price 12v and i need the conection for a peg-perego 12v. Thank you,


hi, you will have change the adapter on the charger or the battery. do you have a peg charger thats not working? if so simply cut the connector off and splice it onto the power wheels charger. the chargers are simply a ac adapter so the only real difference is the connection points. get a cheap volt meter at harbor freight (under $5) and make sure you connect the + and - wires correctly, failure to do so will blow the fuse on the battery and maybe destroy the adapter. from your question im thinking you dont have the peg connector so can find those for sale on ebay or on http://www.modifiedpowerwheels.com . good luck!

Power supply battery charging


You could do it that way, or you can find the problem, if the charger is not working you can buy them very cheap from ebay. hold charger to ear while its plugged in and listen for a hummmmmmmmm, if you hear a hum the charger is ok, next check the coenction at end of charger that goes into the laptop, make sure no pins are loose in this, 3rd, check the conection on laptop for any loose pins. if ther eis loose pins its a big problem.

you can remove the hard drive from the laptop and place it into the same type model laptop and move all your data to a usb key or external driive from it, hope this helps in some way .

Power jack is broke. want to connect to battery pins off motherboard. need pin assignments. i found them for the power jack but cant find for battery connection.


it is nearly just as easy to cut the conection of the power cord and weld it strait to the board where the conection was, or use a volt meter and trace the conections back to some where more stable, conecting strait to battery will or might do damage and the laptop will think it is always running of the battery. and or also could over charge the battery because you are bypassing the switch that stops it. hope this helps a bit.

I have a compac lap top and when i plug in the wall charger nothing happens it wont charge


check to see if you can hear a hum from the charger it self , push the box hard againts ear if its humbing charger is ok, if you cant hear anything from it check fuse to plug. if this is ok then charger is broken.

If charger is ok check the conection into the laptop if it feels loose and when u move it slightly it goes on and off then possible conection to laptop prob.

If this conection is ok and the charger is humbing and working, could be a possible internal switch gone in the laptop that decides to charge and not charge when battery is full. These are always failling on laptops but hopfully its not this.

If you find the charger is broken search ebay for a new or secound hand one, aint to expensive. hope this helps

It will not charge


1. The charger may be damaged To check if the charger is damaged, use another functioning charger. The charger cable has a tiny wire that easily breaks when used without proper care. If the phone still does not charge with a functioning charger, try next step. 2. The battery may be damaged Change the battery and try charging again. If the phone still does not charge with a functioning battery, try next step. 3. The battery terminals may not connect properly with the battery connectors Check the battery connector to see if the battery and the connector connects well. The phone will indicate charging only when there?s enough power supply from the battery. click here Solution Procedure: If problem is confirmed, adjust the battery connector using tweezers to reach the battery terminal and establish connection. Or try next step. 4. The charging pin may be damaged or does not connect well with the board's interface Check the charging pins to see if they are well connected to the mother board. Sometimes the charging pins wear out or loosens from its connection with the mother board. click here Solution Procedure: Check if the pin is bent. Straighten the pin using tweezers. Make sure the board interface is also clean otherwise, you will need to clean it by rubbing its surface using an eraser or brushing it with a board solution. Or replace with a new charging pin. Make sure the charging pin touches with the board interface to establish connection. 5. The CCONT IC for DCT3 or UEM for DCT4 or the "K" resister for non-Nokia models may be damaged If the phone still does not charge after adjustments are made, the problem is CCONT IC for DCT3 or UEM for DCT4 or ?K? resister for non-Nokia models. click here
