Mighty Mule Automatic Model FM143 Review

Installed a large mule, no problem, love it! The Texas weather added another dimension I hadn't thought of: wind. This lock fixed everything! Worry no more - works great!

Installation was easy, although the instructions for the electrical connections could probably have been written more clearly. Now the gate is securely locked with a push of a button on the remote control, which…

Incredibly poor wiring guide for Mighty Mule TS571W (same as MM571W) - so confusing when it can be that simple. Here's the thing guys, if you have a Mighty Mule opener with terminal blocks as shown in the pictures, YOU DO NOT NEED the included lockout board (small board) or the included red and black wires. You ONLY need the white wire. It's easy: (Disclaimer - my opener is set to PUSH to open. I don't think it makes a difference - see instructions) 1. Turn off your knife2. Connect the RED lock
