Larry Posted October 18, 2017 Report Share Posted October 18, 2017 I have a '90 J and am having a problem with the gear horn. The horn will sound for about 1 second, then stop. The throttle microswitch has been cleaned with contact cleaner and hits the detent at the correct MP. The Sonolert was replaced, but still the same 1 second warning. Any ideas?

kortopates Posted October 19, 2017 Report Share Posted October 19, 2017 Check the electrical connection and voltage at the Sonalert and make sure it's wired properly with respect to polarity. Hopefully it's not the voltage that is dropping off. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

carusoam Posted October 23, 2017 Report Share Posted October 23, 2017 It is such a simple system... switch, battery, and sonalert... A volt meter will answer a lot of questions... Wiring diagram is in the POH... in many of our planes.... PP Thinking out loud...not a mechanic. Best regards, -a- Quote Link to comment Share on other sites More sharing options...
Piloto Posted October 23, 2017 Report Share Posted October 23, 2017 I think you have a bad buzzer. I added a Voice Alert gear warning and very happy with it. When turning base at low speed the gear warning buzzer may be mistaken with the stall warning. The Voice Alert clearly identifies the source of the warning. Keeps you from having a belly rub.
