Does anyone know the correct number of the Bulb for the 1980 Instrument Panel Bulbs(TACH/Speedo) Changed them all and started Blowing the Fuse. I put the 194 Bulb in everthing. Should have asked this before I Pulled the Cluster.
Thanks
Thanks

My '78 uses #194 bulbs in the speedo/tach cluster...I don't believe yours is any different. The center console cluster uses #192 bulbs, but the only difference is candlepower.
The only thing I can think of is you may have accidently broken part of the printed circuit on the back of the cluster when replacing bulbs and created a short. The original printed circuit is known to be a bit on the fragile side, even more so after all these years. New ones are avilable, though a bit pricey.

I gotta agree with Owen. I have a mantra with cars...
"It's always something stupid, if it isn't, it's a thousand bucks."
Just take it apart, put it back together carefully, and she'll probably be O.K.
