Here's a page from my WSM. It doesn't mention a relay. In the description of the process it appears as the glow plug heats it reduces the flow of current. This would be how it protects itself from burning up.
I'll study the wiring diagram and look for a relay. Those things confuse me.
I don't recall seeing a relay under the dash but wasn't really looking for one either.
Maybe it's as you say and it's the hour meter clicking. Maybe he dummied it down for me, assuming the time it would take the hour meter to click would be sufficient to accomplish it's task.
Him telling me to recycle if I think it needs more would be to allow the glow plug heat to dissipate into the combustion chamber. As that heat rises the glow plug is going to create less heat until it is doing nothing?
