Sorensen Magnition - huh?

[Onion]

I'm trying to figure out what in the world the previous owner of my Z did with the ignition system. I'm also trying to figure out why my tach doesn't work (probably the ignition). 

 

I've got a PerTronix Flame Thrower coil, and a PerTronix Ignitior. All this then leads to a box labeled "Sorensen Magnition". A google search hardly gives me any info, but does hint at it being a very old system from the '70s. Can someone help me figure out what to do with this mess? What is this Sorensen Magnition thing exactly? I've read about the MSD 6AL ignition on here and it seems to be quite popular, am I right? Any tips on getting my tach working with the current ignition, other than stuff from this thread, which I've already read? 

 

Thanks - kind of clueless with ignition stuff.

What year is your Z?

3/1973. I need to stop forgetting to include that in my posts.

Any way you can snap some pictures of your set up and specifically the wiring to the set up.  I run a pertronix on my one Z, its also a 73 and my tach works fine.  it bounces slightly at 5500 rpm but all other ranges it works fine.

Here's some photos. 

 

Coil. The white wire on the top left goes to the Holley 390 CFM carb. The wire attached to the ground terminal on the coil goes to a kill switch and back. The red is hot. No idea what the black sleeved one on the hot terminal goes to or does. 

 

 

Distributor.

 

 

Another one of the distributor.

Wiring leading to the Sorensen Magnition box, right next to the alternator.

 

 

One more.

Just saw that RockAuto (not Rocky) is offering a generic electronic igntion system for points replacement.  Made by Standard and Airtex, although they look identical.  $158 or 136.  Actually, they look like the Pertronix.  Maybe they're all the same.  The RockAuto Standard product image is attached.

Onion, it looks like you have a module triggering a module.  Pertronix says that the Ignitor is great for triggering an MSD, maybe someone is using yours to trigger a high power (more current) module.

Thanks, NewZed. I'll look around and see if there's anything I missed, but I really doubt it, unless its really well hidden, or in the glovebox which is stuck closed.

Just checked it, nothing. Just the coil, distributor, and the Magnition system.

Edit: Turns out that its a voltage regulator. I've got it figured out. Thanks for the help everyone.
