Do i remove the resistor if i want to install a pertronix ignitor on 74 datsun 620

Depends if you have 3 ohm coil or 1.5, if 1.5 coil then ballast resistor stays.  If 3 ohm no need resistor.  If you bought new, the box should have directions.  You can also go on their website and they have diagrams.  Your dist. has to be a single point or convert dual to single or else will not fit/work..good luck. Forgot to mention that they recommend hi-po coil with pertronix ignitor.  And your spark plugs can be adjusted higher, maybe .035.

The crane I believe usues a optical shutter system under the dizzy cap. a photo would help.

a BIG key for us is the instructions other wise you more or less just have a point conversiona and the power of the spark is the same. Removing of the ballast(heat up the point coil) or changing to a lower ohm coil could ruin the box(draw more current) I say leave it along.

 

If you want simple & hotter spark get a matchbox and a 78/79 nissan coil or the MSD coil.

I think the 520 already has the right coil in there and this should work single point dizzy
