i did find the screws and what not that I was missing along with the optical trigger. I was slowed down for a week or two between work and the fact that I moved my wife's fathers house into my garage while he was moving south. I have my space back again now and am trying to get this going for real again.

I am getting back at it now and am trying to figure out how to remove what I am assuming was the stock shutter. I tried pulling it off and what not to no avail. I don't want to damage anything so I held back. Is there some trick to it? I can take a picture of it tonight if needed but I didn't know if it was keyed somehow or anything like that.

Thanks

Okay, I have a few pictures I took this morning before coming into work. I was looking to see if anyone can tell me how to remove the old shutter. At least, I think it is the old shutter.

Any help would be great. Thanks so much.

SuDZ

Does anyone have any tips for this? I was looking at it again and still can't figure out how it comes off. I tried searching around on here as well but to no avail.

Thanks

I would presume that you need a pulling tool (jaw puller, see image) to remove the trigger ring.

Good idea. I have a pair of pullers I can give it a try with. I was just worried about damaging the metal "pole" in the middle. I will see if it gets it off for me tonight.

Alright, I used a pair of pullers and got the shutter off. It was stuck on their pretty good. I started wiring everything now from the optical sensor to the XR3000. Now I am running it back to the coil and need to buy a replacement clip for that. I will check out a few places today and see what I can find. After that the Ballast resistor is what I will have to figure out.

Thanks a lot. I will keep you posted.

Follow the instruction from Crane and Bypass the ballast resistor. If you haven't already, get a Fireball Coil or MSD Blaster 2 Coil. The OEM coil is set-up for use with a ballast resistor.

I already have the PS-91 so I am going to go ahead and wire that up tonight with any luck.

Any suggestions for mounting these to the body?

I have a xr3000 and a ps91 that was given to me and I am going to install it this weekend. Can anyone give me some info on hooking my tach up with the ps91. I have heard that it will fry my tach if hooked up directly because it runs on much higher voltage than the stock coil. Oh BTW, I have a 73 with the old points dizzy. The coil of course uses a ballast resistor. I do have a tach from a 77 but don't want to use it if I don't have to.

The XR3000 is a transistorized inductive ignition, there should be no problem with the voltage, which is still +12 volt to the primary coil (CDI capacitive ignitions such as the MSD 6A or Crane Hi-6 send ~500 volts to the primary coil, that would be a problem).

The '73 tach is current triggered, check out page 16 of the Crane XR3000 installation guide, which documents a similar setup based on a Smith current triggered tach.

This is not really answering your question, but at least a first step

I know it has been a while but I got off track again. I did wire up the Z so that I have spark again. I am now on to the next part of getting this all up and running.

Thanks again.
