Yours appears to have a wide rubber insulator beneath it while my spacer has a tiny one partially recessed into the bottom of the spacer. Does this difference sound correct to you in that your rubber insulator is nearly as wide as the spacer above it?<br /><br />One other question about the hidden contact. My contacts were fused together by corrosion. I eventually separated them with a dental tool, however the upper contact is a bit thick on one side. Should I try to even it up?<br /><br />Other than that the inner workings look new. After reassembly the horn will only click regardless of how loose or tight the volume screw is adjusted. Any other suggestions?Anonymousnoreply@blogger.com
