Hi skern,
Welcome to the Heartland Owners Forum. If you have a similar switch that operates the front landing gear, it's probably wired the same way. If the wires are off the stabilizer switch, you could probably re-connect the wires the same way they are on the landing gear.
If you're asking because you're trying to trace voltage to figure out why the motor won't run, I've attached a picture that might represent the wiring on your switch. I'm not 100% sure it does, so be careful.
If you have power to the stabilizer motor and it's not working, there may have been some water intrusion that caused one of the brush springs to rust out. 1/3 or 1/2 of a ballpoint pen spring can be a replacement to get things working again.

To follow on with Dan's suggestion about the ball point spring (I might have been the first to do it), wrapping the joint where the motor "seals" to the drive mechanism with a healthy wrap of Rescue Tape will keep water from getting in again. Mine failed a couple of years ago, but has been fine since I took it apart and replaced the flimsy springs.

My electric jack motor quit working today. After tearing it apart I found one of the brush springs had rusted. After cleaning things up and replacing springs reassembled and it works great. I ran a good bead of permatex silicone around the joints as well as where the wires enter the motor. Then wrapped with rescue tape. Hopefully water will stay out. The OEM springs are really flimsy the one on the side where the water infiltrated was pretty well rusted away. Fairly easy to fix just a little time consuming.

John ... having the same issue with mine ... full of water under the boot and water runs out along the power feed when I touch it. How hard was it to get to the brushes? Did you have to remove the motor? I haven't pulled the boot to investigate yet and will just use the manual crank until I have time.
Half of a ball point spring works great.

It's not difficult to remove the motor assembly from the stabilizer and then separate the motor from the drive unit. Once you remove the cover, the brush mounts are accessible. It gets a little tricky putting the cover back on because the long screws have to pass by the armature magnets and they will fight you. You'll have to fish them a bit to finally get them into the holes on the drive unit. I wrapped the cover end with Rescue Tape to seal it.

Well, I pulled to motor apart and it was very wet and burned inside. One of the brush springs and mounts fell out when I removed the armature. I think this may be beyond repair. Looks like I'll be cranking until I have the change for a new motor.

One of my springs was completely rusted away. I bought a spring of similar size and tension at hardware store. The mount should be plastic. If you can get screws out should be able to replace the spring. I replaced the small internal screws with stainless steel screws just in case. I did have a lot of rust inside the case and had to use Emory cloth to clean up took a little time . Eventually was able to reassemble sealed things up with silicone and works great. Hopefully you can fix or perhaps take to someone that repairs electric motors. They are around $300 new.

The manual crank is free and is 10 times faster
