2016 Mercedes-Benz AMG GT S Used Cars in Charlotte, NC 28212. Avg. Dealer Rating: (5 reviews) They have been so great, answered all of my questions and very patient with me when I wasn't immediately responsive due to illness. They worked everything out for an out-of-state sale.
By examining the spark plugâs insulator color, even a less-than-mechanically-inclined person can determine valuable information about the engineâs overall operating condition. Normal: Grey to Light Golden-Brown Color. This condition is ideal, the spark plug and engine air/fuel mixture are operating properly.
The cable pairs are color coded as shown: Each pair consists of a colored wire and a white wire with a matching color stripe. The stripe wire is tip and the solid color wire is ring, referring to the tip of the old 1/4 telephone plug and the ring around the shaft that makes the connections. Note: Plugs/jacks and punchdowns have different color codes!
