Headlight gos dim then bright checked for brakes in wiring and a bad ground and all the plugs all checked out good and at the same time the problem with the headlight started it started to burn out the spark plug. Spark is white in color should be blue in color right?. Install a new plug starts right up but do`nt last long. NEED HELP gredwood@telus.net
