These things seem to differ depending on where they were delivered and the fact that the bulb holders can be switched around easily doesn't help. Mine was delivered as follows: Red = Low oil pressure Yellow = Headlight on Green = Neutral... or maybe not Blue = high beam I've rewired my yellow to flash with the turn indicators 'seems more useful to me.,,

Xt125r neutral light permanently on dash not working

Hi, Howard for your neutral light the usual suspects are:
1. Faulty neutral switch.
2. Grounded neutral light circuit.
If you have a dash, instrument, turn signal, tail lights, and speedometer on some bikes go out at the same time and you have confirmed that the bulbs are good then you need to do some quick diagnostics all you need is a test light and a wiring diagram usually found in the back of your service or owners manual.
1. Make sure your battery is fully charged with "CLEAN" and "TIGHT" connections and the instrument light fuse is not blown.
2. Inspect the bulb socket for corrosion and clean as necessary, a spray can of electrical contact cleaner and compressed air works the best.
3. Confirm your test light is working properly by connecting one end to the battery negative post and touching battery positive post with the sharp probe, the test light should illuminate.
4. With the ignition turned on confirm you have power to the bulb socket by connecting your test light to battery negative or ground and probe the center contact, the test light should illuminate if not you need to check the integrity of the switch or sending unit the light represents, if that is ok then you have a short in the wiring between the component and the light bulb, if all is ok proceed to the next step.
5. Confirm you have a good ground to the light bulb socket by connecting the test light to battery positive and probe any metal part of the socket housing, the test light should illuminate, if not you need to find the short and repair as necessary.
6. Inspect the integrity of the spring loaded positive contact insulation tab by pushing against it with your test light to see if it goes down and springs back fully to it's operating position again contact cleaner and compressed air works best to restore proper function.
7. If your bike has a lot of mileage the vibration can cause bulbs to become loose in the socket by wearing down the soldered contact thus loosing spring pressure from the tab and eventually stop making contact this can be fixed by replacing the bulb or putting a drop of solder on the worn out end to ensure contact.
8. If all of your dash lights are out but are good then you most likely have a faulty connection to the dash wiring harness, inspect the connector for corroded, broken, or loose pins/sockets.

1999 800vs replaced battery when key is turned on to start bike all lights on speedometer light up should be just green just clicks will not turnover

Actually when the key is turned on all the "dash" lights come on neutral, oil, temp and what ever else as soon as the bike starts the lights will go out. If the lights come on while the engine is running then you have a problem or it's in neutral "green".

For the bike not starting a few things, first off the battery even though you say it's new may have been sitting on the shelf for a while and they do loose power so it may need charging. The newer bikes the headlight light comes on when the key is turned on which robs the starting system of power to turn the starter, the batteries need to be good on these bikes or it's just not going to work. If the headlight comes on and looks yellow or amber then there isn't enough power in the battery. If it's a nice bright white light then there is power and the starter may need to be serviced.

If the bike has been sitting over the winter I'd guess the battery has just lost power and requires charging.

Cheers be safe and have fun with your motorcycle

I have a 2002 model r1 and when i start the bike an orange picture stays illuminated on the dash just under the neutral green light indicator. what does the icon indicate so i know where to start looking...

Thats your check engine light...and i hate to say it but bikes have o2 sensors and this is usually the problem. Usually gas that is a little too lean( no fault of can cause o2 sensors to loose sensitivity and cause this error. Always a good idea to take it to someone qualified that can check the engine reading for you.....hope this was helpful...good luck!!

98 roadking classic, replaced the nuetral switch still no indicator on dash, connectors seem good and clipped on tight

To test the lamp on the dash, disconnect the connectors from the neutral switch. Turn your ignition switch on, make sure your "RUN/STOP" switch is in the "RUN" position. Jumper across the connector wires and your light should light up. If not, the lamp is blown or you've got a open or short circuit somewhere.

Good Luck

No power to warning and idicaters

The power to your warning and indicator lights is provide by the "lights" circuit breaker under the dash. This same circuit breaker provides power to your headlight. If your headlight is working, the circuit breaker is not tripped. I would suspect that the bulbs are either blown or have come "unplugged". Since each warning and indicator comes from a different location, it's doubtful that you have a short somewhere.

Good Luck

2007 Honda Shadow Aero blows dash,warning light, neutral light, tail light and license plate light fuse. Intermittent.

try changing the voltage regulator as its running out of controle the charger is over charging and you will boile the battery as well, its all down to the voltage regulator not doing its job right,,,easy fix? buy a new one but get the heavy duty reg and put some heat sink creem on the back of it so the heat can soke away into the frame fast that way they live longer
good luck mike.t

Need to reconnect tail lights,blinkers,stoplight 08 honda crf450x

CRF450x rear wiring is as follows:
Green/yellow stripe-tail light only earth
green-blinkers+tail light.Common neutral.
brown- tail light power
blue- right blinker
orange- left blinker

Make sure the neutral wire from the blinkers are connected on a single line to the green wire from the tail light.

I'm not sure with after market lights so if there is not a connection for the earth there may be a screw point.If you can take the lense of the light you should be able to see the connection points.

Will not start or go into nurtal

Anyway'Lets see turn the ignition key on so you have dash lights etc, Jog the bike back and forth gently while trying to shift the gears, what you are looking for is the green neutral light to come on on the dash.If this does not work..'. turn the ignition off..'. jog the bike GENTLY WITH THE CLUTCH IN AND WHILE THE BIKE IS STILL MOVING A VERY small amount release the clutch.'turn the ignition back on.'Now pull the clutch in and again attempt to shift the gears and activate the green neutral light. If you cant shift down, shift up, if the green lite blinks youve shifted thru neutral go back the other way. When you get a green light pull the clutch in and start the bike. Other Problems.'. You may have an airlock in the clutch line Take it to dealer and have it bled or get a knowledgable person to help you bleed the line. Is your battery OK. Is your kill switch activated.
