glow plugs

I have no problems with my Savage, but I was wondering how do you know a glow plug is on its way out?

If you have a new plug, just look at the differences in them. If your truck is running your plug will have a greyish black bottom on it and the platinum wire will be connected to the outside of the plug. It's pretty distinct when you look at two of them together.
