After having wiring done at another store, the customer came to our store with problems.

Customers who purchased from Amazon.

I tried twice at a shop and once at a major chain store, but the charging didn't work properly after I tried to wire it up. They determined that the problem was with the product, and even after returning it and buying a new one on Amazon, the problem was not resolved.

Kaedia was their last resort, and they traveled over an hour from far away to visit our store.

We will investigate the cause immediately.

We discovered an earth connection to the clamp part of the handle and suspected that this was probably the cause.

The positive side is branched off from the brake switch via a tap.
The shape of this tap is such that it is relatively unlikely to cause any problems later on.

The resistance between the earth point and the negative battery terminal is
It exceeds 1 mega ohm.
The earth connection around the steering wheel is determined by the steering angle.
The resistance value fluctuates between 1 and 5 megaohms.

If body earth is used, 0 Ω is the condition.


First of all, what is body earthing?
The metal part of the vehicle frame is connected to the negative battery.

This is different from the earthing of electrical appliances in your home.

Body earthing is a method of shortcutting wiring by using the metal of the frame.
If you only pull the positive wire, you don't need to pull the negative wire.
It saves wiring.

However, instead of using copper wire, the metal of the frame is used instead of copper wire.
The conductivity decreases slightly.

Easily affected by distance and connection points
Areas that have been painted to prevent rust have a higher resistance.

The cause of this earth failure: (1)
The handlebars are in contact with the frame via the stem bearings.
⑵The handle is painted
⑶The holder is clamped to the painted handle and is earthed.

The no-load voltage was about 12.3V, but due to earth resistance, the load voltage when connected to the smartphone holder dropped to 2V.

Most mechanics are not professionals with electrical equipment, so they often just measure with no load and determine whether electricity is present.

This time, the work was completed by pulling the earth to the battery negative terminal.
Power is turned on without any issues and the smartphone charges perfectly!
I was happy that the customers were pleased with it.
