Hobbit CDI Wiring

Aftermarket CDI

This hopefully will help you wire your cheap aftermarket honda CDI's and should provide enough info to help you figure out whatever other CDI's you come up with. For the stock wiring see here: Honda PA Electrical

There are 5 wires from the CDI stator:

• Black - power out to CDI box
• Pink - timing pulse to CDI box
• Red - lights (high power, need regulator/rectifier)
• Brown -also lights, hook up either or both, brown puts out much less power
• Green - a 3rd output. Fairly weak. Really of no use but maybe you will find one. NOT a ground.

You may receive a CDI setup with different colored cdi power and cdi pulse wires than what is listed above. The alternate colors are:

• black and red - power out to the CDI box
• blue and white - timing pulse to CDI box
• red - lights
• You don't need the other wires

Generic 5 pin CDI

4 or 5 pin CDI

[1-2-3]

[4-5-6]

• 1 - timing input, pink from the stator
• 2 - empty
• 3 - is power out to the HT ignition coil, usually black
• 4 - ground
• 5 - kill switch (grounds to kill engine)
• 6 - power input from the stator, black wire from the stator

You'll need to make sure that the HT coil, the CDI box are grounded and that there is a good electrical contact between the frame and the subframe.

On the hobbit you got rubber grommets at the front pivot connection between frame and subframe and also in the shocks, neither are conducting. This makes a grounding electrical contact between frame and subframe important.

Universal CDI

The plug should match the 5 pin CDI pinout shown above. If you want to use the wire without the plug they are as follows

• yellow (from the CDI box) - power out to the HT coil, black wire to coil
• blue from box - timing in, connects to pink from the stator
• red from box - power in from the stator, black wire from the stator
• black from box - kill switch (ground to kill engine)
• green on box - ground

Check here for schematic of simplified wiring with 5 pin universal blue box

6 pin CDI

These are common and cheap for most modern scooters but should also work for you Hobbit. Some incompatibilities and differences may apply for DC powered and 4 stroke versions with variable timing.

Treats CDI

The above directions are for the 1977 cheap CDI, the Treats one has slightly different wiring as follows: this should be correct, please edit if not.

• Blue/Yellow - Timing pickup
• Black/Yellow - Power out to coil
• Green - Ground
• Black/White - Kill
• Black/Red - Power in from stator

Jog CDI

The Yamaha Jog/Zuma CDI boxes can be found readily on ebay for pretty cheap and have a good 2stroke timing curve. It's timing works well with the stock hobbit stator as-aligned with the woodruff key.

• Red/Black - Power in (to black from aftermarket stator or black/red stock cdi)
• Red/White - timing pulse (to pink, white on stock cdi)
• Orange - ground
• Black - power out to coil (to black on coil)
• Black/White - to kill
