Can anyone explain the electrics on my 2007 EC250? (UK)
2007 EC 250 in the UK
I am hesitating to ask this because electricity confuses me on a good day! I have always had bikes with a battery before but this bike does not. Obviously no electric start and only basic lights (headlight, tail light and stop light). No speedo and the horn runs off its own little battery (looks like one off a bicycle) The headlight dipped beam works (standard incandescent bulb) but nothing else. So... Is it a completely AC system? How do you get things like 12V horn, phone charger, and maybe LED lights to work? Is there any way to check the wiring and voltages without having it running all the time... Sincere apologies if (as I suspect) these are dumb questions... |

You need a regulator/rectifier to turn the AC voltage from your stator to DC voltage(12). Are you sure you don't already have one? You could also measure the voltage at your headlight for example to see if it is 12v DC or if it is AC voltage. If it is 12v DC you already have a regulator/rectifier.

The system is entirely Ac except for the horn. They usually have a horn rectifier which converts the ac to dc.
There is a small zener diode which acts as a regulator for the ac voltage and ensures it does not exceed around 14-15 volts. Most dirt bike run on ac lighting. It ends up looking like square wave Ac voltage which the LED light do not care about and will run fine on.

Thanks all, I have been investigating and the low beam, led tail light and brake lights work fine until I use the left handlebar switch to select high beam. High beam then works fine but the tail light turns off. Which is a novelty!
I am guessing that the tail light is powered from the low beam circuit and consequently turns off when high beam is selected. I shall investigate some more... ps...what does the red switch on the right handlebar do? (all marking have rubbed off the switches) . I have traced the wires and they both go to what looks like a CDI unit under the seat.

Yes..same switch as that so I guess I have a map switch. It does not seem to do much mind?

On my '15 EC200, I run it in the "sun" mode all the time, an the 200 motor has just about perfect power for my needs.

It just retards ignition about 4 degrees. In the mud you will notice it is less likely to spin up. But it takes the bark out of it. Assuming it is still connected properly.

Thanks guys.
I cannot fathom out the lighting issue. When the switch next to the left grip (looks exactly the same as the map switch) is on low beam all is well. Dipped headlight and tail/brake light all work. If I select high beam with the same left switch the tail/brake light goes out. Anyone have any thoughts...? The wiring diagram is not helping. Sent from my LLD-L31 using Tapatalk
