Hi all,
Just got round to checking the voltage to the glow plugs on daughters
07 Connect (they were mentioned in the fault codes) and noticed a connector that looks like it has melted to some degree.Basically there seems to be a small 'fitting' that is mounted off the front of the engine on the n/s that has the thick red wire coming out of the bottom and going to the glow plugs. This fitting also has a threaded stud sticking out of it and the feed from the loom connects onto that (like on an alternator or old ignition coil). The threaded terminal can be lifted out of the fitting and looks like there has been a high resistance connection that has got hot and melted the plastic where the threaded terminal should be held vertical and solid?
Initially I saw little or no voltage on the glow plug bus but after pulling and re-plugging said terminal I then saw ~14V on there (with the engine running).
Googling about it seems it's not unknown but I've not seen a solid reason for it yet? eg. Is it just something that happens when it gets old or maybe due to a low resistance glow plug or poor design? I ask as there is no point replacing the mini loom if it's only going to melt again?
