what coil should u run with electronic distributor. HELP.

[WogsRus]

I've read the forum and all it says is that when converting to electronic dizzie (dr30 l24e dizzy) use an electronic coil. So does thus mean if I run a resistor coil without the ballast resistor, I will damage something. I was told that a non ballast resistor coil runs 9v not 12v.I suspect I should be running a non ballast resistor coil?

no you will not damage anything, a ballast resister coil is still 12v not 9v, the resister drops the voltage to 9volts while cranking then goes back to 12v when running, however I did fit a full 12volt non resister coil when I did mine

[WogsRus]

I suspect maybe tge resistance must be different as my tach jumps all over the place now.

[WogsRus]

SO I put a non resistor coil in and....NG. The car fires up the dies and nothing, backfired all sorts of stuff. Looks like it will be best for me to fix my tacho by running a GT40R with a resistor pack.

 

Bugger it. LOL.

As far as I understand, it is just the opposite. The ignition system runs through the ballast resistor in the run position (approx 9v) to reduce the wear on the points mainly.

The ballast resistor is bypassed in the start position to help increase spark and to help starting.

Might be wrong though.

either way, NG, im going to try the 2.2Kohm resistor trick and see if that works. My tack works, but it just jumps around in steps and not smooth at all.

 

Failing this, a nissan R30 coil to suit dizzy.

Hi,

  Cozza is right. Resistor coils are actually a 9 volt coil but still called a 12volt coil. The resistor drops the voltage from 12V to about 9V to allow the coil to run cooler and also prolong the life of the points. When the key is turned to the start position this allows a full 12 volts through the ignition switch direct to the coil for extra voltage for starting. When the key is released this circuit is disconnected and the wire through the resistor continues to feed about 9V to the coil.

I use a crane 7000 electronic ignition in my 260Z with a Bosch GT40R coil and resistor.

Hope this helps.

The resistor I have which runs a standard dizzy converted to electronic using Pertronix kit is a 1.5 Ohm.  Pertronix recommend 1.5 Ohm if you are leaving the ballast resistor in place and 3 Ohm if you are removing the ballast resistor.
