71 Cuda with Ralley dash Went for a 3-4 hour drive. Stopped enroute, and no power to instruments, I could start and drive the car, no other probs I just installed a 120 amp alt the day before. Sound like a blown voltage relay?

Sorry: Fuel, temp and oil pressure are the gauges that went out.
This happened about a 3 hour drive after I installed a 120 amp alternator. I had a solid state type voltage limiter, and just now replaced it with the same type
The three gauges work fine now. I am going back to a 75 amp alternator just in case that caused the issue
