laytonl Posted Monday at 07:23 PM Report Posted Monday at 07:23 PM I'm having trouble with my gear warning circuit in my 1992 MSE. The Gear warning breaker is tripping. It has a tripped a few times in the past couple of months. In the past, the CB trip only occurred when the gear was lowered. Now the CB does not hold at all. I suspect it is a bad breaker. Any other thoughts before I dig into the bowels of the breaker panel? Note this is just the gear warning circuit; the gear is operating fine. The Gear Warning CB only impacts the floor light, annunciator light, and audible alert. Lee
N201MKTurbo Posted Monday at 07:31 PM Report Posted Monday at 07:31 PM Check that the sonalert is not shorted to the roof of the plane. I had to put a sheet of plastic on mine to keep it from shorting. 1
PT20J Posted Monday at 08:08 PM Report Posted Monday at 08:08 PM I’m guessing that @laytonl’s plane has a tone generator and speaker rather than a sonalert as in my 1994 MSE. The warning CB feeds the down limit switch and the tone generator. I would start troubleshooting by disconnecting the connector to the tone generator to eliminate that. Mine is located on the firewall above the left rudder pedal. If that’s not it, I’d disconnect the annunciator panel next. If that’s not it, I’d check all the wiring. 1
hubcap Posted Tuesday at 12:23 AM Report Posted Tuesday at 12:23 AM Sounds like the bad circuit breaker I had in Myrtle. Replaced it and ended the problem.

I had already disconnected the speaker and the annunciator panel and that didn’t change anything, so it must be the breaker or something in the wiring in the belly. It will be awhile before I can dig in though. Lee
Thedude Posted Tuesday at 02:13 AM Report Posted Tuesday at 02:13 AM I've occasionally been having a similar issue (but the CB resets fine after actuation of the gear). In my case I think the issue is with the annunciator panel because (with the plane on the ground and power off) if I lift up the glare shield and push on/fiddle with the wires in the back of the annunciator panel, the issue is resolved. That's worked twice with a couple of months between issues (I need to get the actual issue figured though)
