SOURCE: shop rider sovereign voltage indication. Brand new fully charged

hi Richard,

Does the scooter actually lose power after the 3 leds show ?

If it is losing power then a suggest to try some other batteries to confirm dodgy batteries, check the terminal connections etc.

If it does not lose power then the volt meter is at fault, if you can check the voltage before riding then after it shows only 3 leds , if there is a big drop, check the charger first to make sure the batteries are getting fully charged.

GeWiz.,

SOURCE: batteries won't charge

Hi. Sounds like there is a faulty connection somewhere between the charger and the batteries. Are the batteries connected correctly. The charger uses the voltage level in the batteries to regulate itself. If there is a faulty connection, then the charge will not operate. Use a multi-meter to check if the batteries are connected correctly. There should be 24 to 26 volts across both batteries.
This fault can also be caused by a faulty charger socket. Check for any signs of melting or heat damage. There might also be a disconnected wire in the plug on the charger itself.Good luck. Neil.

SOURCE: new charger for 36 volt

HI.It should be connected in that way.The + sign of the charger connected to the +sign of the batt then connect the - batt next then finally connect the -sign of the batt and finalle the+ sign of the last batt must be connected to the -sign of the charger.This connection allows the voltage to flow within the 3 batteries.Thank you for choosing FIXYA.

first of all don't use a 12v charger they are for car batteries only
the read flashing light as in low battery ? please confirm ?

SOURCE: Cannot charge the 12 volt battery more than 10 volts. Is there a service manual available

What type of battery is it, sounds like you have one shorted cell. Each battery is made up of 6 cells, around 2 volts a piece. Sorry, you probably need a new battery.
