Glow Plug relay question

[VR6INSD]

i am new to the whole gpr and the ford diesel. i was told i have a bad gpr so replaced it and have been testing it i get agtleast 12 volts on the left side big terminal. when key is turned i get 12 volt to the 3 terminal 2 little and one big left. when truck has been running for awhile i measured it again and i am getting the same reading is this ok or should the gpr turn them off or should they always be atleast 12 volts? btw i live in pennsylvania and its 30 degrees here. the gpr did fix my cold start problem just dont want to burn anything out. the gpr was an ebay purchase hope it was worth it. thanx for the help

I am kinda confused, So you get 12volts on the left big terminal and when you turn the key on you get 12volts on the right big terminal? Then once you start it you will have voltage on both big terminals. I am not worried so much about the small terminals, just clearify whats going on with the big terminals please.
