Why the crap does my glow plug relay make an absolute racket when the ignitions on? Anyone?
Would seem that way, could hear it over the engine!
Bad connection...
That's possibly the relay turning on and off very quickly due it closing the relay, then drawing so much power from the glowplugs, then instantly turning off - if it's a buzzing clicking noise, then I'd go for that
Bad connection though? Wiring all seems fine!
