Default C3 Wiring diagram AM/FM-8track (FCC Data Model GM 2700)

Hi US corvette community and friends,

in my corvette, 1978 Indy Pace Car L48 at, there is an orig. AM/FM-8track installed. 8-track tape is working properly but AM/FM does not work. I receive in germany only the American Forces Network broadcast station in Frankfurt/Germany. I suppose that the radio needs to be modified / fixed because the car installed antenna works and I receive further AM/FM stations w/ another US radio.

To do further radio investigations, it would be very helpful to get a radio wiring diagram / manual (as a pdf file) w/ the following data I've found on the radio chassis:

FCC Data Model GM 2700
Service Ref ' 81YFMT1
Part # 7898490
S/N # 1025184

I appreciate your suggestion and feedback.

Greetings from germany.

Hi Walter

Were you able to get some diagram or manual?
I just pulled my radio fromm a '77 and have the same model GM2700
Service Ref ' 80BFMT1
Part # 7898510
S/N # 1420511
I guess if some documentation is available it will be the same.
If you have any documents, then you could make me really happy if you share it.
Regards from Hungary

Hi,

unfortunately until know I do not have a electrical diagram for this device.

I hope maybe some vette US friends can advise in the near future. In case I'll get support, I'll keep you updated.

Kind regards from germany

Hi,

I really appreciate your advise.

Due to NCRS techn. book H26 on my doorplate indicates Apr. 26, 1978 so there is a good chance that 77 images can work hopefully.

BTW:
Do you as well have a "soft copy manual " for the FM/AM 8 track device available or where to download ?

Kind regards,
Walter

Thanks a lot guys. That can help me already somehow.
As Walter is asking, a manual as pdf download would be now so great.
Thanks again and regards

Those pictures are from an original 1977 Delco radio manual I bought off of ebay.
