Phone switches off when charging using car charger

Mobility scooters can have both fuses and circuit breakers fitted. First check all the silly stuff first. Battery is seated correctly and the freewheel lever is in the Drive position as well as the lights and dials on the control display are working.
The circuit breaker, (or trip switch), is usually a button near the charging port or on the battery box. Press this button and it will reset the breaker switch.
Fuses might be fitted inside the case the batteries are fitted inside. This means you might have to remove the battery box and then dismantle it.
I would recommend you get a mobility scooter mechanic to service it then they will be able to find and fix the problem.

No power, battery, charging and charger issues

This guide contains troubleshooting steps and advice to help resolve issues you may experience when attempting to charge the handset.
After performing each step, please test to see if the issue is resolved.

• No power

Troubleshooting Questions

• Are you using the correct equipment?Make sure you are using an approved Samsung wall charger and USB charging cable. Other brands of charging accessories may have different voltage parameters and could cause charging issues when used with Samsung devices.
• Have you charged your phone for longer than 30min? Leave your phone plugged in to the charger for about 30min without powering on. In some cases, it may take slightly longer for your phone to charge.
  
• Is the battery icon displayed on the screen when charging? After charging your phone for a little while you should get a battery charging icon appear on the screen which will indicate that your battery is charging properly.
  If the charging icon appears, leave your phone for a little longer before you try to switch your phone on.
  If however, the screen is blank and nothing is displayed, follow the below troubleshooting steps.
  
• Is the charging cable plugged into a USB port? Some charging cables can disconnect from the wall outlet adapter and plug directly into a USB port. However, when plugged into a USB port, the charging process is much slower due to the limited power output of USB ports. Instead, plug the device directly into a wall outlet to speed up the charging process.
  
• Is the outlet faulty? Try a different outlet or check for a switch connected to the outlet. If possible, try powering a different device on the same outlet.
  
• Does another USB cable, or wall charger work? Charging issues can occur if either the battery or charging cable is damaged. Verify that the charging contacts are clean. If necessary, clean the contacts using a cotton swab and rubbing on isopropyl alcohol.
  If possible, test the charging cable by plugging it into another device and seeing if the device charges. Alternatively, try charging the device with a different cable. This may mean changing out the cable or the adapter on two-piece chargers.
  If charging through a car charging kit, ensure that the car engine is running, and if possible try to charge other devices using other cables, through the same car kit. If none will charge, then it is likely there is a fault with the car charging kit. It is recommended to continue to cross-test devices, cables, and car kits until the problem device can be identified.
  If the device charges when using a different USB cable or wall charger, the issue most likely lies with the charging accessory. In this case, follow the approved charger repair / replacement process.
  Also, if the charger is connected via an extension or other multi-socket adapter, remove this and plug the charger directly into the wall-mounted socket. This will eliminate the possibility of a fault with the adapter.
  If you are still unable to charge your device, continue to the next step.
  
• Has the phone experienced any shock or exposure to water? Accidental physical shock to a handset can sometimes cause problems to arise with battery or charger, as these components contain delicate parts, particularly. Damage can occur either to the component itself, or to the component's connection to the motherboard.
  Water exposure can also lead to damage of these components, however due to the slow way in which this type of damage can manifest itself, the cause may not always be readily obvious.
  With any physical damage of this nature, the only recourse is to contact the device manufacturer, and follow their approved repair or replacement process.

change the battery.your battery has gone down because of not using it. and even you cannot switch it on by plugging the charger.

where you plug the charger in on your phone, if you look into it you will be able to see the contacts for it to charge.
on the inner OUTER wall of it ther is 2 pins, use a needle to pull them out a little bit but be carefull not to sanp them.
just so they stick out a little bit, if you do this and the charger dont go in then dont bloody force it in otherwise ya buggered.lol
only when the orange light is on its charging, if you accour a flashing orange light do it again.
this should sort your charge problem.
however you will eventuall need to do it again.

It looks like battery is damaged... When plugged in to charger phone shouldn't power on. Try put it on charger when on and see if charging icon appear. (top right corner-battery status icon should change -insted of battery to charging.) Battery is fully charged after cca 4 hours, 80% after 2 hours.

try to change the battery.........

Remove the battery and clean the contact points. Also plug in the charger and try to switch your phone on. Also notice if the normal charging logo/picture is appearing or not. If the phone does not come ON while plugged in with the charger, then its a problem of the phone. However after cleaning the battery, put it back and try to switch ON without/with the charger and let us know the results............sodeep

I had this same problem, it's really irritating. Not exactly a full solution, but if you leave your phone connected to the usb for around 10 - 15 mins then disconnect it, remove and replace the battery and turn it on, it should have enough power to boot up, the just reinsert the usb and it should charge.

the charger has gone bad; get a new one at sonyericsson.com

Here's some instructions to fix this :

It's basically a similar fix for what CTF1800 said but uses paper.
