Guest Hayman Posted October 4, 2011 Share Posted October 4, 2011 Hello, this might sound like a dumb question, but I keep questioning myself about if my 57 is a positive or negative ground off battery, I have no way to look this up.

Guest rsd9699 Posted October 5, 2011 Share Posted October 5, 2011 The braided and uninsulated cable (if original) is the negative ground cable on 57 Olds - true for prior years as well and into the mid sixties before the ground cable became insulated.Ron Link to comment Share on other sites More sharing options...
