Ethel suggested measuring resistance I suggested measuring voltage.  The voltage measurements are easier when everything connected.  Again, put a coin between the points (this makes the circuit "closed") then turn the key to the run position.  Use the multimeter to measure voltage between coil (+) and earth.  The earth can be any bare metal spot on the engine... or the dizzy housing.  

 

If you find 12V on coil (+) with the coin in place, you do not have a ballast resistor in the wiring and you need to add one.  If you measure 6V to 9V, that says there is a ballast resistor or resistor wire in series with the coil.  Let us know what you measure.

 

I don't know specifics about when Minis did and didn't have ballast ignition systems.  Others will have to answer that one.

 

EDIT:  What are you guys doing up anyway?  If you are in the U.K. it's got to be about 2:00 a.m.  Get some rest.  Tomorrow is another day!

ok i'll do all the checks and let you know.

 

its just about midnight now and im up because this is more interesting haha

Now you have pulled the green wire back through the grommet ensure the vacuum advance is free to move the base plate its full range without restriction, you can rotate it clockwise with your fingers

ok will do

[dennismini93]

it was pointed out that the white fork on the points was wrong so iv corrected that but now my battery is flat.....

[dennismini93]

everything was free to move and i cleaned the earths up and its run ok for quite a while now but worried about the amount of time its run without being set up so i havent done any checks yet. going to time it then do fuel and check the dizzy after
