Thanks Eugene. There are bulbs and I tried manually grounding the gauge. Still nothing. I really need my test light but its in the shop with my truck getting a new heater core. I guess I could use a multimeter.

I've seen a few glass fuses that looked OK but the filament was broken right at the end. The end cap hid the break. Sometimes it is evident if you tap the side of the fuse with one finger. The loose end will vibrate while the other stays steady.
