Battery charger for pride victory4. On first plug in power source the battery (onboard) lights up showing red then changes to green then off, and no further response.

Sounds like old exhausted batteries to me.

What if the speed LEDs on the VR2/VSI begin to flash?

• Determine if the battery charger is connected to the power base. When the battery charger is connected to the power base, a charger inhibit feature keeps the power chair from driving. This is indicated by the VR2/VSI speed
  LED(s) flashing.
• Determine if the charger harness fuse has blown. A blown charger fuse can cause the charger inhibit to
  activate.
• Determine if all controller connections are plugged into the power base properly. If the 3-pin charger
  inhibit connector is not plugged in properly, then the charger inhibit feature will activate.

Most pride chargers show up the green light when batteries r charged...when charging u should have a red power led & an orange led ...hope this helps

First measure the voltage of the batteries at the charging socket of the joystick.

John the red flashing light indicates a low battery When you charge the battery your charger should be showing a red light for power and a yellow light. When the batteries are fully charged you should show a red and green light on the charger. Now if you have a voltmeter plug the leads into the two outter holes of the charger port located under the front of the joystick.Without the charger plugged in you will be reading the battery voltage. Fully charged it should read 27-30 volts if you are only reading 20-24 volts then the batteries are low. If you have an onboard charger plug it in and you should read the charger voltage of 29-32 + volts If you aren't getting that voltage then you have a bad charger if you are getting the charger voltage then you have bad batteries and they need to be replaced Hope this helps you

What type and what voltage were the old batteries removed from the scooter?

Aimeelynn I'm e-mailing you the unlock procedure for a VSI controller. If thats not what you have you can e-mail me back the type of controller you have. I will also try to answer the other questions you have

Don your charger is probably not charging the batteries. When you charge your chair overnite the charger should have a red and green light showing charge complete. When you first plug it in the lights should be red and yellow. If you are getting a red and green light when you first plug it in then there is a problem with the charger or with the charging circuit to the batteries. You should have a charger port on the battery box try plugging the charger into that port and see if you can get the batteries charged. When you do you should have a red and yellow light on the charger changing to red and green when fully charged. Hope this helps

No JJR all the plugs need to remain plugged in. On the Pride chairs the light on the charger will only come on green when the batteries are fully charged. When you unplug the controller the charger thinks the batteries are fully charged and the light comes on. Now the problem is the batteries. If they are old or you have a bad battery then the charger never senses a full charge so no green light. Hope this helps

The control systems on power mobility equipment have a "prevent" circuit that immobilizes the equipment while it is plugged into a charger, so folks won't take off with it plugged into the wall outlet. When you turn it on when plugged into a charger, the display will flash constantly, or sweep constantly, depending on the manufacturer. This is normal. Your off-board charger should have a red light to indicate power to the charger, and another light for the charge status. Yellowish means it is charging, when it turns green, you are fully charged. If the status light is green all the time, that is an indication that the charger is not functioning properly, or that the batteries are below a chargeable state. Check charger output, which should be 26-28 volts dc, and each battery should show at least a 12 volt reading, but around 13.5 volts with a full charge. If one or both of the batteries drops below 12 volts after a short period of time, it's time for a fresh pair. Fully charge new ones before using the chair.
