Make a DC circuit for your CBF 125

The CBF 125 has a serious defect. An DC negative electrical system. So, kills with ease and prevents the use of LED’s and other electronic

The solution? Turning things to the battery, but we must use a switch otherwise things are always on. The solution is a relay.

The one i will be has four contacts (pins), 30, 85, 86 and 87. The are connected as pairs, the 30 with 87 he have the switch) and 85 with 86, there is the coil. When passes in the coil the switch allowing current to pass. In words, the aim was to find a place the current pass only we turn on the ignition (and with the engine running), and obviously no longer provide when turned off the bike.

This wire goes to pin 86 (or 85, and 85 connects to ground (aka Pins 87 and 30 (no matter the order) we connect to the 12v from the battery and the the electronics that we want to

To summarize: When you turn the key, current will trough the coil which the switch and this allows the coming from the battery to our gadgets.

The video below the result:

Sounds easy, but the is that all places where I get the signal, the current was the AC, and the relay uses 12v, so the relay wil not Thus the relay does not anything, but I did not quit, I ordered a and a 6v 5v to see if it worked, but also didn’t the problem persisted. Solution

A switch for xenon and no LED’s.

I got a month vacation and there I was to see if it could resolve the matter. And I I was upset over the bike on but engine off) and started to the brake, when my attention, a light. It was the brake light.

Now if this light was working ignition on and the engine off, it only be powered by the battery. I off the ignition and obviously the light no worked. I opened the bike, and the plug on the brake pedal. where 2 wires:

— off: 0v in both;

Honda CBF 125

— switched on: 0v on one, 12v in the other, but braking 12v on both;

— The motor is connected: a 0v, 14v but under braking on both

Note: with the engine the voltage is 14v, not 12v because the is charging.

You found the ideal to connect the relay coil! We connect this pin to the wire has 12/14v in the last two situations.

To this modification you need the usual tools (screwdrivers, etc. ):

— Power Cord;

Ties or connectors (or solder and iron);
