It's not a gary boone dizzy (I was hoping for on one, but I got a deal on
this crane w/ dizzy for under $100), but I couldn't afford it after
replacing tires on 2 cars, a CV boot and an upcoming clutch this month.
I found a wiring diagram by searching the old posts to make sure I'm wiring
correctly.
I couldn't wait to install the electronic ignition, since the points seem
not to work in wet weather(weak spark).
I am bypassing the ballast, but what I was getting at was whether I can run
the Crane XR3000 with a stock coil without frying it.
I've heard that a ballasted coil runs on 6-8V except at startup. Running it
at 12V continously may overheat it and leave me stranded.
Anyone know how to tell the difference between a 6V and 12V coil?
I need to pick up a Crane PS91 coil, but in the interim, I'd still like to
drive.

switching to an electronic ignition, why are you messing with the balast
resistor stuff in the first place? Is this a "Gary Boone" style nissan
ignition that you are switching to, or have I missunderstood what you meant?
If it is nissan style, I don't think you need any kind of balast resistor,
as I believe all of that stuff was to keep the points alive. I am afraid I
know nothing about Crane systems.... I have run MSD and now Jacobs
Pro-street so I can't help there... sorry!
