Troubleshooting a Bennett trim tab system? This video could save you time - it walks through how the system operates and what you should look for first.
Thanks for the video. This was a big help. My tabs would go down but not come back up. I performed the test demonstrated at 1:51 in this video and determined my wiring harness was to blame. After installing a new $29 wiring harness, my tabs are working nicely!
