Good morning, I am new to this site. I just purchased a 67 c/10 and i cant wait to get started. I've always wanted to restore an old chevy pickup and I'm looking forward to this project. My question is about the tail lights. Last night i got the lights to work. But when I hit the brake pedal, the fuse blows and i noticed that the turn signals dont work either, in the cab and at the tail light. Any help or reference would be great. I will also be picking up a 67-72 service manual in the near future. Thank you for any help!
