    Check the resistance from the negative lead of the horn or signals to the main ground on the bike, where the negative battery wire connects to the frame. If you have a poor ground your headlight may be dim too.

As long as your battery has tested good, and it is fully charged, the next thing to look at is your electrical ground. Clean the battery terminals with some emory cloth and also shine up the ends of the battery wires that attach to the battery. Then trace the black and the red wiress to the other end and clean them with emory cloth. chances are that corrosion has made a connection poor resulting in subpar flow of electricity to your signals and horn. Once you have checked and cleaned the battery wires test and see how your signals and horn are working. If they are still weak then you need to open up the signals and the horn and clean up the connections there. get back and let me know how you make out. I know we can solve your problem.

2004 Honda XL 125 V Varadero hi and low beam come on at the same time

Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, dim or surges from bright to dim to bright the first thing you need to check is the headlight bulb for damaged filaments then check your light circuit fuse, then check your head light bulb socket ground wire for a clean tight connection, that being said the usual suspects are:
1. Faulty ground or power supply wire to headlight bulb socket.
2. Worn down solder contacts or loose fit of the bulb base in the socket due to vibration.
3. Worn, chafed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/low beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty headlight relay.
9. Faulty wiring between battery positive and headlight bulb socket.
10. Weak charging alternator/generator/lighting coil
11. Faulty voltage regulator/rectifier ground or overcharging.

Electrical short, No headlight, no horn, no turn signals

may have burnt a wire inside the wiring loom, use multi meter to check each wire continuity, or perhaps jump a wire from + battery to the positive horn wire.
use a fuse on the jump wire in case of short.
If this work then definate break in loom

Speedo, turn signals, brake lights, horn stopped working. All else is fine.

Gap your plugs to 38 thou. Check all your bulbs (one burned out will affect the rest) Take a look at all your fuses and make sure they are all ok. Otherwise you are probably looking at a wiring short which will require trouble shooting of the elctrical system. Buy your self a service manual for your bike, this will help you a lot.

Honda xl 100 1982 wiring problem

i ould start by checking the main engine ground, its a real possibility for your problem and always a good idea, if that does not solve it then i would clean the contacts in the horn button and turn signal control. be careful when opening this as the parts are small and can easily fall out of place
