Hi all

 

just a quick question,

 

I have just rebuilt my engine and changed the points out in the dizzy for an electronic module.

 

the question is how do I now set the static timing on this dizzy now I have no points?

 

its an Aldon yellow Dizzy with no vac advance running on a 1310 mini.

 

any help would be great

 

Thanks in advance :)

There are different methods people use to static time when points are installed.  There is a way to modify one of these methods for use with aftermarket electronic ignitions.  It probably doesn't work for factory modules.

 

To static time an Ignitor type ignition module...

Leave all the wires attached to the dizzy and coil.

Connect a test lamp between coil (-) and earth.

Turn the engine to align the desired timing mark and pointer for #1 on its firing stroke.

Loosen the distributor clamp and turn the ignition switch to the run position.

At the front of the car, turn the distributor housing COUNTERCLOCKWISE until the test lamp turns OFF, then continue about 15 more degrees of distributor housing rotation.

Stop and SLOWLY turn the distributor housing CLOCKWISE until the test lamp JUST turns on.

Switch off the ignition and tighten the distributor clamp.

 

CAUTION:  The Ignitor module used by Aldon is the same as we have in the U.S. sold as "Pertronix".  You must NOT leave the ignition turned on with the engine NOT running for more than about 3 minutes.  There is an issue with Ignitor modules where if they are powered up, passing current, but the engine is not running the electronics can overheat and fail.  Don't worry, 3 minutes is more than enough time to static time the engine.  Just be aware of the time limit.

Is this method as accurate as when doing static ignition timing with points?

[CityEPete]

As long as you can get the engine to run from there I don't see a problem as it will need timing with a strobe once it's running surely, even just making sure the rotor arm is pointing at number one plug lead can be enough ime.

Yes.  In both cases you are turning the distributor SLOWLY until the points/switch just opens.  In both cases the accuracy is based on the amount of mechanical slop in the system and how steady your hand is.  As CityEPete said, in most situations the static timing setting is just to get the engine started and a final timing adjustment at speed typically follows.
