Installation Instructions for 123ignition/2CV |
|
The 123ignition/2CV is designed for the standard (black!) 2CV-coil, and can be used with 12 volt systems only |
|
If you hook a 123ignition/2CV up to a VISA
coil (brown), you are guaranteed to damage the system! |
|
The method of setting
ignition timing is clearly described but you may also use the dynamic method
(using a strobe light). |
Install the unit precisely as follows:
Step 1.
Turn the ignition off. Remove the engine fan, and the rubber shield behind it to gain access to the points box. Note the two wires coming out of the front of the fan shroud. One runs to the oil pressure sender unit, the other one runs from the negative terminal on the coil to the terminal on the points box. Disconnect only this wire from the coil and also from the points box. Do not damage or cut this wire. It may come in useful sometime in the future.
Step 2.
Remove (1) the points box along with the condenser. Set aside (to use again) the two M7 bolts and square washers. Remove (2) the metal protector plate to gain access to the centrifugal advance mechanism. Carefully remove (3) the circlip ring from the end of the camshaft so that you can remove (4) the thrust washer, (5) the cam assembly and (6) the centrifugal weights.
Put these 6 parts in the 123 plastic packaging and store in a safe place.
Step 3.
Thoroughly clean the area, inspect the point where the crank shaft comes out of the block. If the cavity is caked with an excessive amount of oil and dirt, you may have an engine problem.
After cleaning everything, slide the two brass tubes (containing magnets) onto the 5mm spindles at the end of the camshaft. Install the 123ignition/2CV with the two M7 bolts and square washers (must be square washers). Leave the bolts a little loose so that you can still rotate the ignition unit in the housing. Align the dimple at the bottom of the unit with the seam of the crankshaft.
Step 4.
Run the three wires, (yellow, black and red) along the bottom of the fan shroud, and out through the rubber grommet in the front (note this grommet must be intact).Tuck the wires carefully under the metal tabs inside the fan housing, and make sure they can not come into contact with the fan! Now pull the second wire off the coil (i.e. the wire that connects the positive terminal on the battery, through the ignition key, to the positive terminal on the coil). Connect this wire only to the red wire coming from the 123ignition/2CV, using the connectors supplied with the kit.

It is most important that all connectors are properly tightened. |
(On the label BOB is an abbreviation for bobine (coil))
DO NOT CONNECT THE WIRES TO THE COIL YET!
Step 5.
Insert the 6mm timing rod (or a 6mm drill bit) through the hole in the crankcase. Turn the engine over by hand (removing the spark plugs makes this easy) until the rods slides into the hole in the flywheel. Your engine is now set at 8 degrees before TDC (Top Dead Centre). Clean one of the teeth of the starter ring gear and a small area opposite it on the block. The area next to the starter motor works well. With a fresh bottle of Tippex accurately paint a timing mark on the tooth and engine block.
Remove the timing rod or drill bit!
Step 6.
- Make sure the engine is set at 8 degrees before TDC. (step 5)
- Turn the ignition on.
- Turn the 123ignition/2cv housing anti-clockwise until the LED goes out.
- Turn it clockwise very carefully until the LED just comes on again, tighten the two M7 bolts.
Step 7.
Check your timing as follows: Put a wrench on the fan bolt and turn the engine over slowly (clockwise!). The LED should light up at the exact moment when the timing marks you made are aligned. If this is not the case, repeat step 6.
Step 8.
Turn the ignition off. Hook up the yellow wire to the positive terminal on the coil. Hook up the black wire to the negative terminal on the coil. Use the connectors supplied with the kit. Make sure all your electrical connections are secure, a bad connection can cause a major problem in the future! Tidy up everything carefully, e.g. use tie-wraps.
Step 9.
Reinstall the rubber shield, fan (and spark plugs if you removed them).
Double check to make sure the fan does not touch the wires!
Step 10.
A myth exists that you should increase spark plug gap when using electronic ignition it is a myth only!
Note do not allow spark plugs to have a gap greater than 0.70mm, exceeding this gap causes radio interference and puts more strain on your ignition coil and H.T. leads, the same applies even more when using original contact breaker points set up.
Fire it up and enjoy .!

Steam cleaning/pressure washing! Do not steam clean or pressure wash your engine with 123ignition attached remove it and replace when cleaning is finished. |
There are no user serviceable or adjustable parts in 123ignition, please do not attempt to dismantle.
123ignition was conceived in and manufactured in Holland.
