It is a circuit breaker system

The two circuit breakers are one for the headlights, one for all other lights. Power to gauges comes directly from ignition switch. No fuse or circuit breaker for the gauges.

Let the troubleshooting commence. Apply six volts to each isolated indicator and see if it moves the needle. The King Seeley water temp ones move the other way. They go full hot with no power applied and full cold with power. If the indicators work then the senders are suspect. Make certain all wiring has continuity between senders and indicators. Make sure the power is getting from the switch to the indicators. The coolant temp and oil psi senders ground to the engine. The fuel quantity grounds to the frame through the tank attachments.

Really unusual to lose all the gauges at once. As mentioned, there is a terminal on the back of the ignition switch marked "gages". Check that for a voltage reading. On the circuit breaker all the terminals should read approximately 6.3 volts.

Rotor and 42deluxe have good advice. Get yourself a multi-meter, start checking for voltage at the gauge and working your way back. You will find the problem.

This poster asked the same question on the V-8 Club site and it concerned the dash lights for the gauges. He did get and answer over there. This new post now talks about the gauges. Not sure what he really wants to know? Hopefully he will clarify it.
