Mechanical issues on power wheelchairs or mobility scooter usually have something to do with circuit breakers, switches/keys, freewheel levers, cables, connectors, or batteries and its charging.
Direct issues on batteries are likely to occur mostly when they are old. This makes them unable to hold a good charge for a very long time, and not due to them being prematurely worn down.
If the batteries of your power wheelchair don’t hold a charge that long anymore, and you had them for quite some time already — then you might need to have them replaced. However, if they are not that old yet, chances are high that you are not charging them the proper way. For this, you will need to refer to the user manual so you can check out at which part of the process you might have been doing things wrong. And from there make the necessary corrections.
If you honestly think that your power wheelchair batteries are not worn down yet but despite all that your device seems not to get the range it needs, there may be components inside your machine that are too fast in drawing too much energy from the batteries. Like for instance, if the wheel itself is dragging, this can induce your battery to discharge rather quickly.
Below is a checklist for other possible non-direct issues on battery
Troubleshooting steps for mobility scooters not powering up:
- Try to confirm that you have fully inserted your key into the designated key switch.
- Check if your battery pack is snugly fit into its slot. In case that your scooter wheelchair model is not equipped with a battery pack, then you need to inspect your machine’s cables and connections. This measure will help you isolate the issue.
- Make sure that connections for your battery-quick disconnect harness are fully joined together.
- Ensure that you installed your batteries correctly — that is you have the red to positive (+), then the black to the negative (-).
- Confirm also that your machine’s main circuit breaker is not disconnected or tripped.
If Your Mobility Scooter powers up but will budge or move a bit only or just a short distance?
- Before anything else, confirm first that your charger is not connected (wheelchairs and scooters are not likely to move or budge while it is being charged.)
- Always see to it that you set your freewheel lever to drive mode. To verify this, push your wheelchair or scooter a little bit. If it is going to budge a little, then you can conclude that it is in its freewheel mode.
- Inspect your freewheel lever assembly. There are instances that it is not fully engaged.
- Check also your freewheel lever assembly. This sometimes comes with an electrical switch where the wires are heading towards the switch. See to it that the switch and those wires are in good and proper condition.
- Confirm that your scooter’s circuit breaker has not been tripped, and they are in good, tip-top condition. If the breaker or the connections are frayed, there is a good possibility they will only work intermittently.
Anything that will induce your motor to work doubly harder, causing it to draw more energy, will eventually put your breaker in a bad shape like steep hills or bad bearings, or running on thick carpet.
And lastly, ensure that your joystick or throttle feels right. If it produces a queer sound or would not spring back in the usual manner, you may need to check the assembly. When you do this, confirm that your connectors and corresponding wires are in proper working condition.
