96 6.5 i just put new glow plugs in octoberish range, and last weekend my wait to start light never came on. I can hear the glow plugs working, but the light never comes on. Is it the controller, or is there a fuse out that could be making it not work? My glow plugs work, i can hear them. But my light never comes on. Any help?

 

Bulb blown?
Check the connection at the controller for the small wires.
