Hi Trevor, thank you for your reply. I'm not sure if you understand my situation. The battery is new just to cover that. Glow plugs new and relay new. Dashboard glow light only comes on after 20 or 30 on off turns. When glow light eventually comes on, it quickly goes off and car starts and runs fine. The issue is getting the Dashboard glow light on. I don't understand why it takes as many key turns?
