The only concern is that the two sensors may have interference with each other. The idea is to put another toothed wheel rotated say a random 33.715 degrees relative to the first wheel. Now you place the second sensor rotated the same 33.7....etc degrees. So now when you switch sensors the timing is the same. Also the two sensors don't interfere with each other.

Everybody keeps talking about adding another CAS as requiring it to be "in a different position", with an offset. My 3rd-gen CAS sits on a small bracket just behind the toothed wheel on the front shaft. Past that toothed wheel there's a healthy (from memory: 1.5"?) gap from there to the back of the alternator pulley. What's to stop me from making a bracket and putting a second CAS in that gap, facing backward? It would be in exactly the same position as the current CAS, just facing backward. Would they interfere with one another? If so, as an alternative, what about using a second toothed wheel either on top of the first and before the alternator pulley, or if side loads were a concern, on the very end of the shaft past the pulley? --Motorola-A-Mail-icr9nYJh77VTt4W4 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: base64 PGh0bWw+PGhlYWQ+PHN0eWxlIHR5cGU9InRleHQvY3NzIj5ib2R5IHt3b3JkLXdyYXA6IGJyZWFr LXdvcmQ7IGJhY2tncm91bmQtY29sb3I6I2ZmZmZmZjt9PC9zdHlsZT48L2hlYWQ+PGJvZHk+PGRp diBzdHlsZT0iZm9udC1mYW1pbHk6IHNhbnMtc2VyaWY7IGZvbnQtc2l6ZTogMTZweCI+VGhlcmUg aXMgbm90aGluZyB3cm9uZyB3aXRoIHRoYXQgaWRlYS4gVGhlIG9ubHkgY29uY2VybiBpcyB0aGF0 IHRoZSB0d28gc2Vuc29ycyBtYXkgaGF2ZSBpbnRlcmZlcmVuY2Ugd2l0aCBlYWNoIG90aGVyLiBU aGUgaWRlYSBpcyB0byBwdXQgYW5vdGhlciB0b290aGVkIHdoZWVsIHJvdGF0ZWQgc2F5IGEgcmFu ZG9tIDxhIGhyZWY9InRlbDozMzcxNSI+MzMuNzE1PC9hPiBkZWdyZWVzIHJlbGF0aXZlIHRvIHRo ZSBmaXJzdCB3aGVlbC4gTm93IHlvdSBwbGFjZSB0aGUgc2Vjb25kIHNlbnNvciByb3RhdGVkIHRo ZSBzYW1lIDMzLjcuLi4uZXRjIGRlZ3JlZXMuIFNvIG5vdyB3aGVuIHlvdSBzd2l0Y2ggc2Vuc29y cyB0aGUgdGltaW5nIGlzIHRoZSBzYW1lLiBBbHNvIHRoZSB0d28gc2Vuc29ycyBkb24ndCBpbnRl cmZlcmUgd2l0aCBlYWNoIG90aGVyLjxicj5CaWxsIEplcHNvbjxicj48YnI+PGZvbnQgY29sb3I9 IiMzMzMzMzMiPjxpPjxzcGFuIHN0eWxlPSJmb250LXNpemU6IDE0cHgiPjxmb250IGZhY2U9InNh bnMtc2VyaWYiPkNvbm5lY3RlZCBieSBEUk9JRCBvbiBWZXJpem9uIFdpcmVsZXNzPC9mb250Pjwv c3Bhbj48L2k+PC9mb250PjwvZGl2Pjxicj48YnI+LS0tLS1PcmlnaW5hbCBtZXNzYWdlLS0tLS08 YnI+PGJsb2NrcXVvdGUgc3R5bGU9IjsgYm9yZGVyLWxlZnQ6IDJweCBzb2xpZCByZ2IoMTYsIDE2 LCAyNTUpOyBtYXJnaW4tbGVmdDogNXB4OyBwYWRkaW5nLWxlZnQ6IDVweDsiPjxkaXYgc3R5bGU9 ImZvbnQtZmFtaWx5OiBzYW5zLXNlcmlmOyBmb250LXNpemU6IDE0cHgiPjxiPkZyb206IDwvYj5D aGFkIFJvYmluc29uICZsdDtjcm9iaW5zb25AbWVkaWFsYW50ZXJuLmNvbSZndDs8Yj48YnI+VG86 IDwvYj5Sb3RhcnkgbW90b3JzIGluIGFpcmNyYWZ0ICZsdDtmbHlyb3RhcnlAbGFuY2Fpcm9ubGlu ZS5uZXQmZ3Q7PGI+PGJyPlNlbnQ6IDwvYj5UaHUsIFNlcCAxNSwgMjAxMSAxNzo0NTo0NiBHTVQr MDA6MDA8Yj48YnI+U3ViamVjdDogPC9iPltGbHlSb3RhcnldIFJlOiBUaGUgZ29vZCBuZXdzIGFu ZCB0aGUgYmFkIG5ld3MuLi4uLi48YnI+PGJyPjwvZGl2PjxkaXY+DQogICAgPG1ldGEgY29udGVu dD0idGV4dC9odG1sOyBjaGFyc2V0PVVURi04IiBodHRwLWVxdWl2PSJDb250ZW50LVR5cGUiPg0K ICANCiAgPGRpdiBiZ2NvbG9yPSIjRkZGRkZGIiB0ZXh0PSIjMDAwMDAwIj4NCiAgICBPbiA5LzE1 LzIwMTEgMToyMSBQTSwgVHJhY3kgd3JvdGU6DQogICAgPGJsb2NrcXVvdGUgY2l0ZT0ibWlkOmxp c3QtNTEyNTc3NkBsb2dhbi5jb20iIHR5cGU9ImNpdGUiPjxzcGFuDQogICAgICAgIGNsYXNzPSJB cHBsZS1zdHlsZS1zcGFuIiBzdHlsZT0iLXdlYmtpdC10YXAtaGlnaGxpZ2h0LWNvbG9yOg0KICAg ICAgICByZ2JhKDI2LCAyNiwgMjYsIDAuMjk2ODc1KTsgLXdlYmtpdC1jb21wb3NpdGlvbi1maWxs LWNvbG9yOg0KICAgICAgICByZ2JhKDE3NSwgMTkyLCAyMjcsIDAuMjMwNDY5KTsgLXdlYmtpdC1j b21wb3NpdGlvbi1mcmFtZS1jb2xvcjoNCiAgICAgICAgcmdiYSg3NywgMTI4LCAxODAsIDAuMjMw NDY5KTsgIj48L3NwYW4+VGhlIENBUyByZWZlcmVuY2VzIHRoZQ0KICAgICAgY3JhbmssIG5vdCB0 aGUgcm90b3IuIMKgIElzIHRoYXQuIEl0Pzxicj4NCiAgICA8L2Jsb2NrcXVvdGU+DQogICAgSSdt IHN0aWxsIGNvbmZ1c2VkIGFib3V0IHNvbWV0aGluZyBteXNlbGYuIEV2ZXJ5Ym9keSBrZWVwcyB0 YWxraW5nDQogICAgYWJvdXQgYWRkaW5nIGFub3RoZXIgQ0FTIGFzIHJlcXVpcmluZyBpdCB0byBi ZSAiaW4gYSBkaWZmZXJlbnQNCiAgICBwb3NpdGlvbiIsIHdpdGggYW4gb2Zmc2V0LiBNeSAzcmQt Z2VuIENBUyBzaXRzIG9uIGEgc21hbGwgYnJhY2tldA0KICAgIGp1c3QgYmVoaW5kIHRoZSB0b290 aGVkIHdoZWVsIG9uIHRoZSBmcm9udCBzaGFmdC4gUGFzdCB0aGF0IHRvb3RoZWQNCiAgICB3aGVl bCB0aGVyZSdzIGEgaGVhbHRoeSAoZnJvbSBtZW1vcnk6IDEuNSI/KSBnYXAgZnJvbSB0aGVyZSB0 byB0aGUNCiAgICBiYWNrIG9mIHRoZSBhbHRlcm5hdG9yIHB1bGxleS48YnI+DQogICAgPGJyPg0K ICAgIFdoYXQncyB0byBzdG9wIG1lIGZyb20gbWFraW5nIGEgYnJhY2tldCBhbmQgcHV0dGluZyBh IHNlY29uZCBDQVMgaW4NCiAgICB0aGF0IGdhcCwgZmFjaW5nIGJhY2t3YXJkPyBJdCB3b3VsZCBi ZSBpbiBleGFjdGx5IHRoZSBzYW1lIHBvc2l0aW9uDQogICAgYXMgdGhlIGN1cnJlbnQgQ0FTLCBq dXN0IGZhY2luZyBiYWNrd2FyZC4gV291bGQgdGhleSBpbnRlcmZlcmUgd2l0aA0KICAgIG9uZSBh bm90aGVyPyBJZiBzbywgYXMgYW4gYWx0ZXJuYXRpdmUsIHdoYXQgYWJvdXQgdXNpbmcgYSBzZWNv bmQNCiAgICB0b290aGVkIHdoZWVsIGVpdGhlciBvbiB0b3Agb2YgdGhlIGZpcnN0IGFuZCBiZWZv cmUgdGhlIGFsdGVybmF0b3INCiAgICBwdWxsZXksIG9yIGlmIHNpZGUgbG9hZHMgd2VyZSBhIGNv bmNlcm4sIG9uIHRoZSB2ZXJ5IGVuZCBvZiB0aGUNCiAgICBzaGFmdCBwYXN0IHRoZSBwdWxsZXk/ PGJyPg0KICAgIDxicj4NCiAgPC9kaXY+DQoNCjwvZGl2PjwvYmxvY2txdW90ZT48L2JvZHk+PC9o dG1sPg0K --Motorola-A-Mail-icr9nYJh77VTt4W4--
