Glow Plug Time Delay Control

OK guys this is my first time on a forum.
I have a 1997 F350 7.3L and I was having a starting problem. I finally put a volt meter on the relay feeding the glow plugs and discovered that the power was coming on after a 20 to 30 second delay. This does not correspond with my dash indicator at all. I assume there is a time delay control somewhere. Could someone help me locate it. Is it adjustable or do I simply replace it?

Thanks

that sounds like the relay is sticking. as soon as the key turns on you should hear the relay click

I also put a toggle switch in the power line to the GPR so I can kill the juice going to it when I don't need it. I never liked the idea of them going on when the motor is hot and its hot outside. ps, welcome
