C50 AIM pages

[Edward B.]

If you've been following my post on my 1969 C50 SWITCH AND HARNESS thread, you'll know that the 1968 and 1969 AIM's are incorrect with regards to the wiring diagram. So this has peaked my curiosity. When did the wiring diagram finally get fixed in the AIM?

If anyone out there can take a look at their 1970 through 1975 AIM's (probably sheet A1) and let me know if it's different than my 1968 and 1969 AIM's (see attached), I'd appreciate it.

Thanks
Ed

1970 is re-drawn, but the drawings are the same. They just re-formatted the page and made the page landscape rather than portrait and moved View A to the lower left rather than upper right.

1971 shows lots of changes. I have two drawings with a total of 8 changes to the revision record
Item 3 an optional switch added 3998399 (looks like 2-24-70 for the date, but it is hard to read, so I may be wrong on the date)
Item 6 clip 3748083 removed 2-24-70 & clip 3748083 (19437) added 2-19-71 -- looks like all they did was add the coupe designation for that clip.
View B was added 2-19-71 showing wire routing for 19437 and the note "routing for 19467 only" added to the main wire routing image.

1972 same as last 1971.

I have no scanner at home and for some reason the NCRS board doesn't like me posting images. I have probably worn out my welcome. Maybe the information ablut the optional switch will help you.

Re: C50 AIM pages

Thanks for the info Terry. Do any of the drawings change to reflect the 3 wires going to the switch instead of just the (incorrect) two?

I only have AIMs to 1972 and all of them clearly show two wires at the switch. I did not look at the 1968 & 1969 because you did not ask about those years.

Re: C50 AIM pages

So at least up to 1973 the AIM was wrong! Amazing.

Thanks Terry.

Can anyone with a 1973 or 1974 AIM comment? Maybe even 1975? I think the entire assembly changed in 1976, but I'm not sure.

I don't think I would phrase it that the AIM was wrong, although certainly in some cases it is. We can not rely on drawing details for configuration determinations. The shape of the head of a fastener or the style of clamp are not details that are necessarily drawn accurately in the AIM. I suppose the number of wires going to a switch could also not get changed as drawings are updated. The installer of the part only cares about the part number of that part and that it installs in about the same way as the predecessor part. If a plug has two wires or three wires is of no consequence to the installer, and thus to the AIM draftsman, so long as the plug inserts into the connector.

Ed,
Here is a picture of the C50 taken from my 73 AIM as requested. Hope this helps.

Re: C50 AIM pages

Terry, I totally agree. This isn't the first mistake I've found in AIM's. By the way, did you send me an email? If so, can you send it again? I accidentally deleted it.

Thank Jimmy. Looks like 1973 is incorrect as well. I would be willing to bet that 1974 is correct though, because that's when they went to the rocker switch. Anyone with a 1974 AIM care to post?

Yes I sent you an email through the discussion board. If you send me your email address I will send you pdf.s of the five pages from 1970-72 AIMs. We can not send attachments to emails sent through the board, so I have to have your email address. This board is blind & dumb.

Thanks Terry. I just sent you an email.

Re: C50 AIM pages

I can post the page(s) from the '74 AIM later this evening, after I get home. I also have the '73 AIM, but that one has already been posted.

Re: C50 AIM pages

Thanks Joel. That would be great.

Re: C50 AIM pages

Took a while to find the page in the AIM, and it ain't a very good representation, but here it is. Page date 3-13-73, with no notations.

Board will not allow a full sized file...had to reduce the size. I have the full sized image loaded on My web page, if that's better.

Re: C50 AIM pages

Well, that's very interesting! Correct rocker switch, but the harness STILL shows only two wires! I wonder if they EVER fixed it!

I believe the last year for this option (in its early C3 configuration) was 1975, so if anyone has the 1975 AIM, can they post a picture?

In 1976 they went to RPO C49 instead of RPO C50, so I'm not sure what the differences are, but I think it was a completely different design. Maybe someone with a 1976 AIM can verify?

Thanks Joel. I DO appreciate it.
