@camperman63 yeah remove the screw and the switch drops down. The plastic housing needs to be prised apart (you can see the join) and will need to be glued back together after or as I did, zip tied it together so I can reapply grease should I ever need to again. I did it on mine and it’s work flawlessly ever since through all weathers.
@camperman63 no not tricky, it was awhile ago I did it. I think it was probably a small flathead to prise it open. It’ll be fairly straight forward once you pull it off and see how it’s all put together. Just clean it out real good and pack it back with plenty of dielectric to keep out any future water 👍
I used quite small zip ties to fix it back together, if you want a photo let me know and I’ll post one up
