Batteries wont charge

SOURCE: My blackjack wont charge

I did a hard reset because i was having the same problem with a new battery and a new charger. I took my sim card out first to prevent any possible data loss. then followed the following steps:

1. Once the handset has rebooted to the Today Screen, enter the following code: *2767*3855#. The handset should display a message “Formatting- Please wait a moment”.
2. The phone will reboot after the Full Reset as this is normal operation.

The Sonic has an off board charger. IF the scooter is not charging, you may need to replace it. If you a technically inclined, you can measure the voltage out of the charger, it should be more than 28 V. You may need to contact Pride for more help.

I have the book if you can figure a way to post you email without getting too much SPAM. Be sure the charger is un-plugged, and that the free wheel lever is engaged.

sounds like a 12V drain on the system, like a trunk or glove box light that won't shut off.> Could be many. many other reasons why. The way I would find the draining circuit would be to remove the neg cable of the battery. I then would connect a 12V test light between the neg battery TERMINAL and the neg battery CABLE. With a 12V drain the light will shine. I would install into the light a 9V battery powered recepticle to hold computer and radio station memory. Then I remove fuses 1 at a time, then reinstall, at the same time looking for the 12V light to go out. Hope this helps.

replace the charger. It may have weak or broken internal wiring, loose connection end, or it is just fried out. You can use a multi-meter to test charger. If charger is good, than you may have bad capacitor inside psp
