Hello,
I have Audi a3 2007 1.9 tdi bls engine and i recently tried to mess around with my glow plugs trying to test something and I think I burned 3/4 of them (infinity ohms. no continuity. I assumed glow plugs receive 12v from the harness, so I removed the harness and connected them directly to the battery one by one for like 5-6secs. There was some sparks at first and then they went silent. So after that I looked at glow plugs and saw they are rated for 5v o.o (bosch duratem)
So what went wrong and how does it work? Can anyone shortly explain please? Do they receive 12v from the harness and I just connected them to battery for too long ?Or somewhere along the line (at glow plug relay or somewher else) the voltage gets lowered to 5v or lower and I connected them too way too high voltage and hence they dead?
Thanks in advance
