    I've been asked to e-mail the Whizzer wiring diagram quite a few times, so I thought I'd just put it on the site. For some reason, I couldn't post the pdf file of this even though it's well within size limits, so I rescanned it as a jpg file and resized it so it should print out at actual size. It just isn't as high quality as the pdf file.
    This is for the WC-1 and NE-5 models. I'm not sure if the NE-R uses the same wiring harness. This diagram will not apply to the Ambassador.

    Just a side Bar from Helmutt

    During the process Of designing a fine Kit Bike Frame system Powered By the whizzer Motor. there was the Ugly detail of the wiring and the Modules. Hanging all over out in space???

    This detail was addressed with the dual rail frame design.. and being perfected with the New Helmutt Frame system. Made On purpose to be Hiding the Ugly modules Inside what looks to be a tool Box.and Using the right side frame rail for Conduit wiring inside the frame

    The CID,ACDC relay,voltage regulator Modules,Ket Switch,fuse,and the Battery all House Inside this simple fix, "the tool box" with a hiden vent for the wire to inter and travel out of.... then with a Mutistrand 9 wire. diving out through the vent,into the right side frame rail, used as conduit going forward to tie the forward Handle bar Control leads/ The wire connects are then Junctioned In the Back Cavity of the Head Lamp, as is done on many Motorcycles.... this simple Idea did cleanup,and protect all of this vulnerable vital articals,and still allows all of the electrical Functions that came On the Modern replica whizzers.. Running lights, dual beam head lamp,Brake lights, horn, lighted gages with Tac functioning.. as Is shown here with Joe Persons Fine Build We sent Joes Helmutt Bike frame Kit system with Color, and Modified whizzer center stand, and prewired.. ready for Joes Lovly final assembly. Feel free To call,and ask if ya Have any questions about this detail/or the general electrical of the stock Whizzer Motorbike 602-405-0394..

    The pdf file finally...

    With the recent change here to a new server I thought I'd try to upload the wiring diagram in the pdf file one more time. My previous attempts were unsuccessful despite the file being well within limits. Lo and behold I was successful this time, so here it is.

    I just wanted to Thank You Quenton for all your help with my wiring harness. Without your help I could have never got that bike running. Your knowledge of all things Whizzer is truly amazing. Going out of your way to help me even in the midst of the Portland show and other things in your busy schedule is greatly appreciated! You are truly a great ambassador for Whizzer motor sports enthusiasts!
    For anyone new here, who does not know who Quenton is, he is the leading authority on whizzer motorbikes and will go out of his way to help anybody who asks him. I just wish I had known him before I had started my project because he could have saved me hundreds of dollars more than he did!
    Quenton, that new H-motor will be will be coming to you for that rebuild as soon as I can find a Tillotson ML5B Carb. I can't seem to find one anywhere. Anyone who has one please contact me @ lillback44@yahoo.com.
    Thanks Quenton for all your help,
    Chris in Ft Wayne
    Ps: sorry I took so long!

    Isn't that the same lilback that had a hussy fit and said he was done with the forum and its people? I'm guessing my suggestion didn't work either?
    Bike came out so nice after quenton tackled it, that you pieced it out on eBay huh?
    Only option I see for you is try to buy the knowledge.....wait!.....you are

    Ambassador wiring

    Any help in getting a diagram for an Ambassador? how much difference is the diagram in this thread? I'm helping a friend with his bike. no spark at the plug.

    NE Ignition Wiring_Model.jpg Best if you contact me if the following information doesn't help, as there are several parts that are different from the standard harness.
    The CDI and the tachometer are very different as they appear to be digital [Ambassador and NE-r Tachometer won't work on earlier models].

    Make sure the green wire on the CDI ISN"T at ground when trying to start. Also check to make sure one side of the coil is grounded. If the rear wiring harness is un-pluged it removes a hidden ground and won't fire.

    I have found several issues in the wiring at the CDI plug as the wires are reversed. I will attach the basic ignition wiring diagram for the later motors. Please note pins #5 & #6 on the CDI as this is where the wires were reversed on several Ambassadors.

    If this doesn't help, please contact me directly and I will help you restore fire to your motor.

    Have fun,

    First off want to say it is refreshing visiting this site with the caliber of people that are on here.Back in the early 60's had a few Whizzers one made a restoration project out of it. Then it was on to Harley Davidsons,still own them. A few years ago picked up a 1999 Whizzer finally getting to the stage where it's time to get it going. The motor has been completely redone now an NE5, Picked up a new Harness of course my wiring diagram is different the color codes are not matching. Looks like some of the wires that should be solid have different color dashes.

    Was hoping there is a wiring diagram available that has the correct color or at least the same as my new harness.

    NE Ignition Wiring_Model.jpg Hi Mike,

    Best to use the original harness if you have it. There are many different versions of the harness, and they aren't compatible. The biggest differences are the rear harness assembly, and the Molex connectors from the stator.

    As far as I know there isn't a schematic for the later versions, however they are wired the same [lights, CDI, horn, charging system, regulator, AC/DC relay, turn signals, etc], just different color wires, and different plugs. Be very careful where the rear harness plugs into the main harness, as there is a "hidden" ground, often missing on certain versions. The motor will not fire with the rear ground missing. Most of the time the "hidden" grounds are dark green wires.

    You should be able to follow the original schematic and trace the wires to the components.

    If needed you can go into detail here and I can help you "connect the dots". Like what to do if the stator plug is different and has 2 external wires instead of 1.

    Have fun,

    Thank you very much for the rear harness tip will be vigilant for that. The plan is to only run head and tail lights with horn. Wonder if the new harness has provision to connect any grounds to the frame.
    One other thing I need is the lower triple tree bearing race part # 5047 is that still available?

    Hi Mike,
    Try Whizzer USA for the bearing.
    The harness normally has a ground connector near the battery wires. The rear harness "mystery" ground is not attached to the frame, rather connecting two wires together near the rear Molex plug.

    Have fun,

    Hi Quenton, finally got my 99 Whizzer running it purrs like a kitten and the lake pipe (well you know) My brothers kit bike turned out to be a real brain fry. We finally set it up to use a timing light immediately saw a difference between his and mine. His having the 6 wire module mine the 5 wire. His has the electronic advance once the engine is off idle. I had to drill the flywheel and add another small tab of metal to the advance side of the trigger to final get his engine to idle good and take the throttle. The fuel mix is close to perfect.

    Sounds like a great plan to me.

    I currently have an adjustable ignition on my OHV Whizzer and hope to have some time to play with it soon.

    Have fun,

    Adjustable ignition? well that sure sounds interesting. After looking at our engines the only solution was to move the trigger tab on the flywheel. After studying the situation machine work would be required to move the pickup module.
    Been out and around the neighborhood with mine the hopefully the centrifugal clutch will start seating soon same with the new drum brakes. Sure brings back good memories out putting around on that bike.

    Guess you have heard we have been making an American made auto clutch for both versions of the Whizzer[vintage and New Edition].

    Have already shipped well over 200 for the new edition bikes, and over 20 for the vintage Whizzers [we are currently tooling up for the vintage clutches].

    Most of the OHV Whizzers are converting to the new clutch as it is the only one that will hold up with the extra power.

    You can remount the ignition sensor and the flywheel trigger in a totally different location in order to advance timing past 23 degrees. I am running the advance at 35 degrees on my 1999, and 40 degrees on my Dirt Drag Whizzer.

    Have fun,

    You have peaked my interest again, one the different location for the ignition where and how, the other is the OHV engine. Sounds like your new auto clutch has caught on.
    I have noticed that the two different ignitions fire the plug at different locations on the flywheel trigger one as the leading edge of the trigger contacts the sensor the other at the trailing edge.
