Orange wire where does the orange wire hook up at, the wire is in the main wiring harness next to the carb on the right hand side of the bike

Obtain a good work shop manual the wiring diagram should be in the back.

There could be many issues causing no spark on a 04 GSXR750. Check for battery voltage on the orange/ white wire at each coil. If none this model has a history of a failed right hand handlebar switch and or connector. Ignition voltage passes through this switch. Also check the main harness connector under the left side fairing panel near the area of the turnsignal for internally broken or corroded wires. If all this is good check the signal generator(crank position sensor) output voltage with a "peak reading " voltmeter. This is a special type of meter or attachment that must be used. The voltage should be 3-7 volts DC at cranking speed. Good luck.

You should purchase a wiring harness for the install. If your vehicle had the vehicle side of the harness cut out, try www.mobileinformationlabs.com for wiring diagrams.

The two carbs are not balanced to each other. Balance as follows; Start the bike then increase the idle on the left carb to a high idle. Now unplug the right cylinder and the engine will slow down some. Now slowly turn the idle down on the left carb until the engine just dies. Hook up the right plug wire then do the same proceedure for the right carb. Now both carbs are balanced. Hook up the left wire and start the engine again. The bike will be running faster than you want so now adjust the idle screws on both carbs equally to get the desired idle speed. Please rate my answer. Thanks.

WELL IS THERE TO RED WIRES AND AN ORANGE WIRE TO ELEMENT RED WIRE COMING FROM TOP WIRING HARNESS GOES TO THERMOSTAT ORANGE WIRE GOES TO OTHER SIDE OF THERMOSTAT AND RED WIRE FROM BOTTOM OF HARNESS GOES DIRECTLY ON HEATER

the power terminals from the trailer arent direct connected to the battery terminals.when you are plugged to the mains the battery is charging and disconnect [via a relay perhaps]the orange terminal from batt+.try to make anew connection from the trailers battery terminals with a new fuse separated from all trailers circuit'use 2-2.5 mm*cables and a 15amps fuse.connect the yellow and red to+batt and black to- batt.

there is a resistor inside the ignition on the black box you need, twist the RED and ORANGE wires, the orange wires are actually one wire split into two further down by the connector so cut the red and orange wires from here. you then need to join the ORANGE/YELLOW wire to one end of the resistor and the BLACK/WHITE wire to other end, clean up and protect with electrical tape and snip other two wires, you dont need them. now can you tell me what colour wires connect to each other on the right handle switch, i need to know the colours of the wires on the switch side where it connects to the main wiring harness (both sides plz say which is which!!) cheers mate

This information applies to the vast majority of Honda motorcycles. Colors for the right handlebar switch are: Grey sends power to the turn signal switch. Light Blue goes from the turn signal switch, to the right turn signals. Orange goes to the left turn signals. Light Green goes to the horn button.
The left handlebar switch: Yellow With Red stripe goes to the starter button. Black wires take power to the headlight switch and the kill switch. White goes to the headlight low beam, Blue to the high beam. Brown / White goes to the tail light, running and instrument lighting. Black / White comes from the kill switch and delivers power to the ignition coils.
I hope this helps.

Hi and welcome to FixYa,

Pls see your other post, but basically:

• in most, one end of the red wire is connected straight to the battery's + terminal. The other end of the red wire goes to the main fuse;
  
• the black of course as you posted goes to the ground;
  
• interchanging the 2 wires from the starter relay would make no difference;
  
• the starter relay is not directly grounded;
  
• the starter relay's + wire goes to the starter button;
  
• the starter  relay's - wire goes to starter cut-off activated by safety interlocks (neutral and clutch lever).
  

Good luck and thank you for asking FixYa.

If you are mounting the unit to the bars or fairing, I would recommend using a power lead which is available in the fairing, rather than the AUX accessory switch.  The AUX switch sends power to a connector under the seat, in front of the battery.  You would need to run new wires up under the fuel tank, along the neck and into the fairing to connector your Zumo to the AUX.  Instead, there is a 12+ V switched ignition power lead which is not used on U.S. touring bikes and would be perfect for connecting your Zumo.  Pull the fairing off the bike (7 screws, TORX T-27) and look at the headlight harness, which is 3 wires, black, white, yellow.  Attached to this harness will be 2 wires, a black and an orange w/ white stripe.  The orange will have a red silicone cap over it to prevent it from shorting out in the fairing.  Cut the zip-ties which connect these 2 wires to the headlight harness and then hook it up to your Zumo, black is negative, Orange positive.
