Hey I Have A 1982 380sl That Burns The Rotor Just Beneath The Point That Discharges To The Plugs ,the Center From The Coil Is Fine. I Checked The Coil Wire To The Dist. For Resistance And It Didnt Read Any So I Replaced The Coil Wire. The Car Ran Fine, Great Actually And Now Its Happening Again The Rotor Is Burning Like The Spark Is Coming From Beneath The Contact Any Ideas???
