 |
|
I have a simple alarm system for canopy and gear warning in a Rutan aircraft. Microswitches on the nosewheel, throttle, and canopy latch. This has worked fine for years. Now I notice that when I switch on the master, and when I switch it off, I'm getting a very brief "chirp" from the warning buzzer. This system is not connected to anything else, (except for power and ground of course) so is standalone. Could this be simply aging of the microswitches? Any thoughts before I contort myself to access the nosewheel switch under the instrument panel? FYI - 12 volt system, master switch is a solenoid operated by a toggle switch.

The vast majority of electrical problems are due to bad connections like poor crimps, loose fasteners, and corroded terminals. Switches need exercising to remove corrosion. Not saying a bad connection is your problem, but it is something to check.
