Imported C4 Corvette - 1987 Significant Battery drain - need wiring diagrams

[mchughfamily@bigpond.com]

Hi All,

Im new to Corvette's and new to this forum and was directed here by a friend.
I bought an Imported  C4 Corvette manufacture / build date of 1987.
I have a significant battery drain - some 3 amps. Sounds like a lot.
The Auto Electrician in Bathurst has asked me if I have wring diagrams and if not to obtain some if possible. The issue appears to be from the Curtesy / Interior lights circuit. Can any one help a very desperate new owner. Please!
I'm a member of the Goo Blass (Orange NSW Historic Vehicle club), but its not a dedicated Corvette club - with lots and lots of different car brands and models, so my help there is very limited.
Regards,
Brendan
Thank you to 'GTC' who sent me a link to the Electrical Wiring diagrams at Corvette parts worldwide. I immediately bought and downloaded the info - brilliant. Great web site too.
Thanks so much 'GTC'
