Hi all new to the group
Recently brought a GU 4.2ti 2003 series 3
Had it just over 2 weeks now started being a prick to start on cold mornings so I replaced the glow plugs all was good after that .
Decided to change my trailer plug from round Pin to flat pin plug and decided to hook up my LED spotlights all was good after that took it for a drive no problem at all .
Went out the next morning car wouldn’t start only would wind over found I had no power to my glow plug bar thought that was odd

Hooked the positive from my battery straight to the glow plug bar it then started i then Replaced the glow plug relay it started straight away

Went out this morning wouldn’t start again after glowing several times but did after hooking the leads up again to the glow bar Is it possible I’ve fried yet another relay I thought that it would go through my fuse first or could it just be a earth problem
