Resolved Verify CAS disk orientation 1g green top

[Anfurnyy]

Title says it all pretty much.
I need help verify that I have the CAS disk installed the correct direction and not flipped backwards.

I pulled it apart to block off the big window in it for my Kiggly 12-1 tooth trigger and I was in a hurry and didn't pay attention to which direction it needed to be.

Here's how it's currently installed:

Kiggly picture shows the disk flipped the opposite way..

and other pictures of the disk I've found online are the same as mine But wanted to verify.

Been a while since I opened one up but I would assume Kiggly's drawing is correct, also assuming you did this for a standalone ECU, it doesn't honestly matter, it's just used to reference which phase the motor is in.

If Kiggly's is right then mines backwards and could explain my my car has such a hard time starting. Doesn't generate an RPM Signal..

I'm using a link g4+ PNP but it's got a bunch of other BS attached to it.

From the 1G technical service manual:

Note the arrow showing direction of rotation. So, as shown in this diagram, you’d be viewing the disc from the driver side while it’s installed.

I'm spatially challenged at this time of night but based on all the pictures I have yours seems to be correct.

I can't visualize what the diagram in the DTM would look like if they showed it in the the actual direction of rotation (counter-clockwise) but note how the disks pictured have the little inner slot lagging the closest outer when moving CCW same as the DTM shows with a CW rotation.

Just mirror the diagram from the manual to visualize orientation as if viewed from the passenger side. Agreed, it appears correct.

I did something like that a long time ago when a similar question was raised but never verified my impression. And last night I could hardly think my way through all the conflicting information.

Well thanks everyone, it seems the mystery has been solved then. Mine is installed correctly. I'm not sure what Kiggly's diagram is doing

I'm not sure what Kiggly's diagram is doing?

Looks like he cut and pasted from the DTM to show that the TDC slit needs to be masked off in this use case but didn't fix the issue with the DTM image.

Oh yeah you're right.

I still wonder why the DTM has that image backwards. Seems odd.

Well just to round back on this, this was not the cause of my starting issue.

It was a matter of Falling vs Rising edge triggers. But this is a good post to have on file in the forums anyways.

Thanks fellas.
