Assuming stock configuration the violet/white wire is hooked to the VOES and the appropriate wire is grounded to the chassis. Ensure you have appropriate VOES for your style bike. A VOES set up for a light bike if installed on a bagger could potentially cause it to run advanced under load, which could cause predetonation (very harmful/destructive to engine). Hope this helps. Google Harley VOES and you'll find similar information. FYI the bike will operate in a normally retarded condition without input from the VOES. At high vacuum, such as when in cruising and not under load, the VOES will advance the spark, which will improve gas mileage. Certain aftermarket ignitions dispense with the VOES.
Yes, an '84 Harley Davidson FXR can run without a VOES (Vacuum Operated Electric Switch) switch, but it may not perform optimally. The VOES helps adjust the ignition timing for better performance and efficiency under different throttle conditions. If removed, you may experience reduced power and efficiency, especially at lower RPMs. It's generally advisable to keep the VOES or replace it if it's malfunctioning for optimal engine performance.
What is the Vacuum Operated Electrical Switch (VOES)? What does it do and why is it there? All Harley Davidson motorcycle carbureted models since the 1984 model year have used the VOES to improve throttle response, increase MPG, and meet EPA requirements for emissions. The VOES is a motorcycle part described as a vacuum ignition retard device. That is, under low vacuum conditions the switch is open and has no effect on ignition timing. Under high vacuum, the switch closes and advances ignition timing. Essentially, the VOES is like the vacuum advance in older type automotive distributors. The VOES is a normally open vacuum operated switch that closes under 3-5" of vacuum. The switch is connected to a lead from the ignition module. Under high vacuum, 3-5 inches or higher, the switch closes. A lead from the switch to ground closes a circuit in the ignition module. This circuit advances the timing of the spark. The advance increases throttle response and decrease fuel consumption and emissions. The vacuum hose is usually connected to a port on the carburetor or intake manifold depending on motorcycle year and carburetor. There are several different VOES switches used the mounting bracket style and operating vacuum being the main differences. The FLHT models have a different vacuum range than the other models. However, just about any VOES can be adapted for use by adjusting the point at which the switch closes. The point at which the switch closes. The switches can be adjusted by removing the potted plug and adjusting the setscrew. You will need an accurate vacuum gauge and vacuum hand pump. We have been able to set the operating point as low as 2 inches and as high as 7 inches. Why would you want a VOES? We have experimented with converting 1972 and later ignitions from points to electronic ignition. We have used Dyna 'S' conversions for H-D's. We have used Crane, Compufire, Spyke and other Harley Davidson conversion kits. With some of these such as the Dyna 'S', you still have to use the mechanical advance system. This requires service and routine maintenance. Others work very well having digital advances and provisions for a VOES switch. We experimented with installing a VOES in a 1983 FX and found we have improved throttle response and better mileage. We also routinely install the VOES in custom built Harley Davidsons and even our own Kenny Boyce framed Harley FXR's use VOES with a Crane HI4 module. During Dyno runs, we found that part throttle roll on power was increased as was throttle response. We believe that most street ridden Harley Davidson motorcycles will benefit from a VOES. For racing applications or supercharged, turbo-charged or bikes using Nitrous Oxide, we do not recommend using a VOES. This is due to the possibility of a sudden timing change causing a backfire which can be a bad thing under these conditions! Source: http://www.directparts.com/static/articles/harleyvoes.html
Run a toggle switch from battery to ign. side of ign. switch.
On a 1998 Harley-Davidson Fat Boy, the VOES (Vacuum Operated Electric Switch) is typically mounted on the left side of the engine, near the carburetor. It's attached to the intake manifold and is used to enhance performance by adjusting timing based on engine load. If you're having trouble locating it, consult the service manual for detailed diagrams and specifications specific to that model.
First of all it's vous! not voes! It means "you are my love, my life, my everything.
If you remove the VOES, you can use a multimeter to test a charge across the terminals. When 0 pressure applied to the vacuum port, the resistance should be infinite. Once the correct amount is applied, resistance should fall to near zero. Caution should be used, since adding too much suction to the vac port can damage the VOES.
jae is not only voes

If it is a 2-wire switch- yes If it is a 3-wire switch- no
bad relay, bad switch, headlamp bulb is faulty, an improperly grounded wire. You didn't specify as to which model you have...
To wire a single pole light switch, first turn off the power to the circuit. Then, connect the black wire from the switch to the hot wire in the electrical box, and the white wire to the neutral wire. Finally, connect the ground wire to the green screw on the switch. Turn the power back on to test the switch.
To wire a light switch to a light, first turn off the power to the circuit. Connect the black wire from the switch to the black wire from the light. Connect the white wire from the switch to the white wire from the light. Finally, connect the ground wire from the switch to the ground wire from the light. Secure all connections with wire nuts and cover with electrical tape. Turn the power back on and test the switch to ensure it is working properly.
