If the battery charger on your Evatac flashlight blinks from red to green repeatedly when you connect the batteries to the charger, it could indicate a problem with the batteries or the charger itself.
Here are a few possible reasons why the charger is blinking from red to green:
The batteries may be faulty or damaged. In this case, the charger may not be able to charge the batteries properly, causing it to blink from red to green.
The charger may be detecting a problem with the batteries, such as overcharging or overheating. In this case, the charger may be designed to stop charging and start blinking from red to green as a warning.
There could be an issue with the charger itself, such as a loose connection or a faulty circuit. In this case, the charger may not be able to properly charge the batteries, causing it to blink from red to green repeatedly.
It is recommended to check the batteries and charger for any visible signs of damage or wear, such as corroded or dirty connections. If the issue persists, it may be best to contact the manufacturer or a qualified technician for further assistance.
When the red light is on it is to indicate that the charger is getting power from the wall outlet. If there is a second light that normally comes on Green when charging pay close attention to it when you first plug the charger in. See if it blinks even once then turns off. If it does that means the charger is not seeing any battery voltage at the plug that goes into the chair. If the green light does not blink at all then it usually means the charger is defective. Also most wheelchair battery chargers will not charge the batteries if the chair is to dead to even turn on.
It means the charger does not see any voltage from the wheelchair. If the batteries are very low or completely dead the charger cannot start charging. Each battery needs to have approximately 9 volts left in it.
Sounds like you have a bad charger. If you have an on board charger, plug it in to the wall and test the voltage at the charger port at the front of the joystick between pins 1 and 2 (the two eyes of a happy face). If you get between 26 and 28 volts and the voltage rises as you charge, then the on-board charger is OK. If not check the AC cord and connections to the charger, including the lego black block and/or connection of the charger at the controller. The type of connection depends on year and serial number.
If you have an off -board charger plugged into the front of the joystick, check your voltage directly at the batteries with the seat flipped back. With the off-board charger plugged into the front of the joystick measure the voltage being applied to the batteries at the large black 2 pin plug coming from the controller to the batteries. When you take this measurement leave the plug connected and put your digital voltmeter probes in the connector at the back (non-contact side). With the charger on, voltage should read between 26 and 28 Volts or come to that voltage after some time.
On board chargers run about $200 and off board chargers around $300.
Invest in a good AC cord if yours is questionable. For $8, I have fixed many of these chargers with a new AC cord from Radio Shack. Hope this helps.
The disconnected wire may be inside the junction box inside the motor assembly, or on the leads connected to the battery and fuses. If all of those check OK, contact Invacare for service. If your insurance purchased the power chair for you, they will most likely cover the cost of any repairs. Good luck!
Firstly, it is bad news to use an extension cord with the charger as it can get very hot. It will sometimes take 8-12 hours to get a full charge on the batteries. If the light does not go to green on the charger, the batteries may be damaged and not able to take a charge. This is especially true if the Power chair was stored after your father in law died; the gel in the batteries may have gone solid. The lights on the controller will go left to right then back if the charger is connected properly.
The brake release knobs both need to be in the UP/DRIVE position for the motors to engage.
The cord is probably ruined either by the dog or by folding the cable when you pack it up. The charger brick itself is probably fine but you will need to buy a new charger cable. Contact ASUS to determine how much that will cost.
