tommy.h Posted January 14, 2011 Share Posted January 14, 2011 Hi Mark you will find in the weather we are having now that the GLOWPLUG LIGHT will only flash on/off very quickly. the colder it gets the longer it will stay on. i can post a test for the wiring harness but not for the relay itself. if required tom Quote Link to comment Share on other sites More sharing options...
