Had a couple of occasions where the fuel gauges and oil temperature gauge (which is also electrical) went to zero. On checking the 5 amp Engine Instruments circuit breaker, I didn't find it "popped" but as soon as I touched the button the gauges came back. It was as if there was a poor contact within the breaker itself. Has anyone experienced a problem like this? Could it be a breaker that is going bad? How difficult are they to change? The breakers themselves don't seem too expensive (<$10 from Aircraft Spruce). This is in my 1969 PA28-140.
