Whizzer wiring

After hundreds of requests I agreed to supply a lot of information on the wiring and wiring harness.
Whizzer has offered several different versions of the harness, but the basics remain the same. Often wire colors are changed by one of their vendors, but is usually exchanged with a similar color.
The most common problem is the loss of grounds or the misunderstanding of the 2 ground system. All "black" wires are ground. All "dark green" wires are ground. In order for the motor to fire only a few items are needed. If the battery isn't used [to smooth out the current] several items won't function correctly. The ignition circuit only needs a Coil, CDI, alternator [stator], and the ignition sensor to power the motor. If you use a battery and don't use the AC/DC & regulator modules, the battery will most likely not survive. The horn won't work correctly without the battery. The turn signals & brake light will cause the lights to operate poorly without the battery. Most Whizzer owners leave the key switch on and run the battery down. If the battery is completly down, the motor most likely will not charge the batter up full, and will require charging with a small battery charger. If the ground on the coil is missing the plug will not fire. If the ground on the CDI is missing the plug will not fire. If the kill switch is shorted to the handlebars the plug will not fire. The horn is activated by attaching a ground to the horn [via the horn button]. The key switch shorts the green wire on the CDI to ground when in the off position. The kill switch shorts the green wire on the CDI to ground in the off position. The ignition switch should be used when a battery is used with the complete haness, becuse it allows the lights to work off the battery when the motor isn't running. All orange and light blue wires are for the turn signals. Green wires with a red stripe are usually the brake light system [however I have seen green with a yellow strip used]. If the turn signals don't flash it is most likely in the switch on the left handlebar needs cleaned. Tail light bulbs burn out often if ridden on a bumpy road. the most commonly replaced parts are the tail light bulb, the headlight bulb [special], turn signal flasher, and the coil [broken spark plug cap or wire pulled out of coil body]. Most people that modify the harness have problems with the ground circuits. I have found it easier to hide the extra wires as opposed to removing them. The later wiring harness has a ground circuit in the rear light plug [motor won't fire unless the rear of the harness is plugged in. The following items have a ground... coil [green wire is the ground], CDI [black wire is the ground], regulator [black wire is the ground], AC/DC relay [black wire is the ground] key switch [yellow wire with a red stripe is ground] kill switch [green wire is the ground] battery [black wire is the ground]. The gray wire on the horn is 12V [with motor running or with battery] The horn, flasher, and brake light switches aren't grounded. The 3 wires for the front head light are ground [black wire], and the other 2 are for high and low beam [controlled from the left control assembly. the 3 wires for the tail ight are ground [black wire], tail ight [yellow], and brake light [usually light green with a red stripe]. There are many extra yellow and black wires in the harness to power the guage lights [speedometer & tachometer]. If the fuse is blown the motor will most likely still run, but the lights won't work with the motor off.
It is necessary to connect the green and black grounds together if only using the minmium wiring system.
The current stator is 81 watts and will make the horn work correctly without a battery.

Hope this information is helpfull, if more information is needed just ask.

Very good information Quenton.

I have two questions. I had my harness replaced under warranty. The dealer just tucked the backlight wire to the speedo, behind the plate on the forks. I haven't found the connector on the harness to hook it up. Could that be missing on the new harness.

Second question...Is the flasher for the signal lights in the system or do I need to add it. I have a box full of various motercycle turn signals that I may put on instead of the fairly expensive Whizzer ones.

Thanks!

There should be several connectors in the new harness for the speedometer & the tachometer back lights. They are usually black [ground] and yellow [switched 12 volts]. I have seen a few speedometers & tachometers with only the yellow wire because the black was grounded to the case. The flasher is available as a seperate item, or is included in the turn signal kit.

Howdy, Quenton,

Excellent information, as always. Thanks.
And now the question...

Once I was forced to get into it, I found the wiring diagram
in the service manual for my '07 NE-5 to be fairly accurate.
But I'm still wondering about the AC/DC relay....

I was thinking about putting a white strobe light on my Whizzer
in hopes that it might make me more visible to some suburban
motorist blasting along in their SUV while talking on the cell phone.

But the low-rent strobe I bought wants 12V DC. I would like it come
on when I fire up the bike, without having to throw a separate switch.

When the alternator kicks in and the AC/DC relay switches to AC,
does the battery act like a big capacitor and sop up the ripples in
the current? And, how safe do you think it is to hook up other
12V DC things? Like, say, a GPS....??

The yellow & black wire in the front harness should supply the power you need. The yellow wires are 12V from the battery and then switches to the 12V from the stator. Another place to aquire 12v is one side of the horn.
Have fun,

Thanks, Quenton,

I'll try that with cheap 12V stuff first before I try more expensive accessories.

And, if I get nuts, I'll haul the oscilloscope down-stairs to the Whizzer and take
a look at the 12V signal before and after the AC/DC relay switches over.

Head light / tail light /brake light

All,

finally got my Whizzer Phantom built and the basic eletrical connected to get it to run... thanks Quenton and what fun!

Now I am trying to connect an aftermarket headlight, taillight (with brake light function with no luck so far and my harness does not really seem to match the wiring diagram in the manual. Here are the facts:
  • Stock Wiring Harness
  • No battery
  • Stock left and right controls
  • Got the kill switch working.
  • Want to use the H/L headlight switch on the left as an on (H) off (L) switch for an aftermarket headlight... which wires from the harness connect to handlebars control wires and which to the headlight?
  • Tail light - which wires on the rear of the wiring harness connect to the tail light?
  • Brake light - have the switch on the right brake lever ... what should I plug that into on the wiring harness? What wires on the rear of the wiring harness should I attach to the brake light bulb in the taillight housing (Have a seperate bulb for tail light and brake light in the same housing)
If more information is needed from he to assist please let me know...

thanks ya'll

Adam

Hi adam I would use A battery eleminator from the motorcycle world in place of A battery , This would keep from spikeing and blowing bulbs ..I dont think the regulator is big enough to handle the amps on A high rev.... Hope this helps Bill Green

Hi Quenton,
My name is Chris and i'm new to this forum. I don't even know if this is the proper way to ask you a question or not, but here goes. I have a pacemaker 2 I bought in pieces and i'm trying to get back together. I bought a new wiring harness (old one chopped up.) and a new CDI, voltage reg, coil, and key ignition. All of which plug up nicely. The only one not sure of there is the coil (spark plug). The only wires that seem to go to that are a blk/y and blk. I have that hooked up blk to green and blk/y to blk on coil?
The other question is the wires coming off the harness. I have a red and blk to battery, a stand alone blk that I put a hoop on and connected to battery cover post, where I sanded paint off to achieve good contact. The other wires coming out are the y,w, blue/y and a blk/brn that stand separate. The wires coming from stator are same colors(maybe the only place in this harness) and connected to the ones from the harness. Tail light harness is plugged into main harness but not to anything else. I'm going for minimum wiring for spark. Horn I put the pink and brn. No light , turn signal, speedo.
In one of the last things you said in your post was" It is necessary to connect the green and black grounds together if only using the minimum wiring system." I'm assuming this doesn't include wiring for lights and such that aren't hooked up? I'm about to give up on this project. I posted for help but didn't get any response. If you see any mistakes in what i've done or have any input at all on this please contact me. Any help would be greatly appreciated!
