I was flying at dusk this evening when I ran into this issue.
I have a breaker-switch to activate my electric fuel pump. Crimped on the ring terminal on the pump side of the breaker-switch is a 2nd small wire which runs to a green LED on my panel to let me know when the pump is running.
Today I noticed that the green LED was glowing faintly when the switch was off. I would turn the pump on and the LED would glow bright green, turn it off and the LED would go off. Then later in the flight it would start to glow ever so slightly.
Is it possible that the breaker-switch is making a very small partial contact. Enough to excite the LED but not power the pump?
Sounds like I need to replace that breaker-switch as I hate to 1/2 power the fuel pump.
