My landing gear aural warning was becoming quirky. Occasionally, it wouldn't sound at all, but most of the time it would, but when the throttle was pushed forward, it would take almost full throttle before the horn would stop. Something was not right. My 74 C has electric gear, a throttle quadrant and uses a squat switch, not an airspeed switch in the warning circuitry. There are lots of iterations of the landing gear warning system, but if yours matches mine, I hope you find this of use. To make a long story short, there were simultaneously two issues: 1. The throttle micro switch had gone out of rig. 2. The sonolert was failing. I took some pictures while I had the quadrant apart and found that there is a small access to the micro switch from the left side of the quadrant under the panel material. One does not have to open up the entire quadrant to get to it, but only minor adjustments can be made through the access hole. My aircraft has two sonolerts. On the pilots side is the stall warning horn. On the copilot's side is the gear warning horn. it is a Mallory SC628P. I found new ones on eBay for less than $15. I uploaded the pictures to Mooneyspace at:
