hi, we are fitting a crane fireball electronic ignition system to our GQ 4.2 carby type patrol, hubby just wants to clear up a queery before starting the job;
do you bypass the ballast resistance on it, as in the instructions some tell you to bypass and some go through it,
thanks from chris.

If the unit runs on 12volts by pass it ..................... if on 9 volts don't bypass it.
In my patrol I left the points as one good thing about carby and points is you can always get them going good enough to get ya home. When the "magic" box destructs it's frustratin knowing the problem but not being able to do anything about it. lol

how do you know if it's 12 or 9 volts? and hubby is doing it so if it ever packs up while away he can just plug in our old dizzy to carry on and get us home, just means carting around a dizzy (don't suppose they take up that much room)
thanks from chris

Chris ....... CDI unit will most probably 99.9% be 12 volt power supply I would say and should be marked in instructions. Could see no reason for it to be run on 9 volts as it would be if ran thru the ignition ballast system.

if it has a ballast resistor then the COIL is 9V ...... that is what the resistor is for, it "normaly" starts on 12V (bypassing the resistor) and then runs on 9V to help the points last longer ...... dont bypass it ..........
The CDI will run on 12V but i would NOT assume that it picks up the power supply from there anyway, take it from an "ignition" supply ..... i would take a good look at the wiring diagram again ..

Yeh Chris Agni is right,
All CDI units run at 12volts to my knowledge, did your new unit come with a coil?
If it didnt get a new 12 volt high energy coil and bolt it on with the new system,that way you will get the full benifet from you new system. You can bypass your resister and tape up the wire so if need be you can fit the old unit, you can still run the 12 volt coil with your old dissy without reconecting the resistors higher energy systems will allow you to increase the plug gaps a little also maybe to 0.09 or 0.10 to help the burning process, try some more advance to but be aware off pinging under load. If you need anymore info drop me and email @ my web site.

If you use Pirana ignition , you can put points an condensor back in to standard
if it fails .no modifications
