    I checked the voltage at idle and it's showing 14.

    check to see if the ground wires are good... get a long four foot wire (like 18 gauge) hook one end up to the negative terminal and then slit the ground wire on the plug to the dim bulb and connect it... see if that solves the problem.

You need to see what voltage is at your battery at an idle, with a meter first.

    14 is a little high at an idle. If it goes higher than that as you rev it up, you might be looking at your voltage regulator. This keeps your volts around 12.5 to 13.5 range.

Lights go dim when rev engine


Hi, Anonymous if your headlight is not working, only one beam works, keeps burning out, blinking, or is dim 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, chaffed, or broken wires in the light circuit.
4. Corroded, broken, or loose pins/sockets in wire connectors.
5. Faulty hi/lo beam switch.
6. Faulty ignition switch.
7. Fuse is good but no continuity on both sides.
8. Faulty wiring between battery positive and headlight bulb socket.
9. Weak charging alternator/generator.
10. Faulty voltage regulator/rectifier ground or overcharging.

When sitting at a light at idle, the headlight goes dim. Then when I rev up and drive normally, the light go up to normal.


The light gets brighter because the higher crank speed is generating more electricity. Your battery is getting weak. Check to see that water covers the top of the plates in each battery cell. A strong battery will make up the difference at idle speeds. Most bike batteries will only last two years or so. Please rate my answer. Thanks.

How do i check my charging system or does a bike shop have to do?


Best way would be with a volt meter. A more simple but not foolproof method is to start the engine, turn on the lights rev the engine up, if the headlight gets brighter as the revs increase it is charging.
