Frank Rhobotham Posted November 26, 2018 Share Posted November 26, 2018 Hello all, I have a cmb24d driving my mini trees. I accidentally hooked up a cable that had a short in it on channel #6. Now that channel stays lit. It works but is always on dimly. Did I destroy that channel? thanks, Blaine Link to comment Share on other sites More sharing options...

Frank Rhobotham Posted November 26, 2018 Author Share Posted November 26, 2018 Awesome, thanks for the offer. If I’m in over my head I will reach out. Do you know which mosfet is used on that board? Maybe amazon can get it to me? thanks again. Link to comment Share on other sites More sharing options...

You are very welcome, keep in mind that with stranded wire all it takes is for one little strand to go astray and it will short something out.

k6ccc Posted November 29, 2018 Share Posted November 29, 2018 Frank, glad you got it fixed. In reference to Mr P’s comment about one stray strand of wire, check out this thread: I am now using ferrules on all new construction and am slowly retrofitting older stuff. 1 Link to comment Share on other sites More sharing options...
