Electric wheelchair repair service—restore electric wheelchairs for customers | Correct non-original rear lenses that have been modified indiscriminately

Electric wheelchair repair service - repair electric wheelchairs for customers free of charge | Correct lens damage after non-original modifications

Received reports from customers that the electric wheelchair suddenly stopped when it was fully charged.

We are very confident in the quality of our products and feel that this sudden power outage is abnormal. After inspection, the master found that the wheelchair had been modified from the original factory and was poorly made. To install a reverse rear lens for automobiles (12V), use additional wires (brown) to draw power from the controller to supply the rear lens.

It turned out that the user went to a company that advertised repairs and repairs were done haphazardly.

There are traces of pinching on both ends of the modified wires. It should be that during the modification of the spot welding, pliers were used to weld the spots, resulting in poor wire connection and forced power withdrawal, which prevented the battery from being fully charged. At the same time, the wires overheated and also It is easy to have accidents.

Poor workmanship and repair issues

1. Poor wire workmanship

2. Electric wheelchairs usually use 24V voltage, and automotive supplies usually use 12V voltage. So the lens was very bright, but at the same time it was super hot, causing the electric wheelchair to burn the circuit board. This maintenance company didn't know that this electric wheelchair ran on 24V.

3. Forcibly spot welding on the computer board circuit to obtain electricity, which wastes electricity and cannot be fully charged, causing the wire to overheat.

📍Easy to modify, difficult to repair📍

Since both ends of the wire have been welded, if the brown wire is removed, the red and blue wires will be damaged, 🔌 causing unstable power supply, or even sudden power outage, and damaging the battery.

deal with

You need to cut off the modified wires, replace the bad parts with the original computer board, restore the modification, and repair the battery at the same time.

📢 We hereby appeal to everyone to try to avoid non-original modifications to avoid damage to wheelchair parts and functions, and to avoid accidents
