Fitting the transient suppression diode, P6KE33CA, which is an odd thing with 2 anodes. Then some conformal coating with UV glue. Then some testing in the garden.

I use UV hardening acrylic resin all of the time, because it is clear the UV passes trough it all of the way to the bottom. It is not a real glue because it cannot be hardened between two objects.
(unless on is glass or UV conductive plastic) This looks like a suitable use for the stuff.
The sun will finish any unhardened spot soon enough. I charge such batteries with 13.8 Volts.
corrosionx lifts heat glue a little btw.
Haha, everyone said to use heat shrink tubing! But you are a BlueTak guy!! Guess what, lol.
Last fall a piece of the gasket that seals the hood like device on the front of our Class A Motor Home came loose. It kept sliding off every time I checked the oil, which, caring for my engine condition, I do at every fuel up. So when we got to our winter quarters, I drove up to a local hardware store, and the fellow behind recommended this tube of stuff to fix it. I took his recommendation and bought the stuff. A few drops of it, and the gasket is fixed, so I am left with a nearly full tube of the stuff. Well about a month later, the handle on the microwave/convection oven came loose, in order to fix it, you need to disassemble the entire door, not a chore for an old man, so I took the black stuff and glued it back on, it is still working just fine. Well this summer I built a nice little ghost detector for my niece, who is into that crap, and I needed to cover the resistors and wires that were exposed, my mind turned to that tube, and I used it to cover the top, yep still working great and the stuff is impervious to water, it goes on and really looks like wire insulation and dries in just a minute or so. The stuff is made by 3M called BLACK SUPER WEATHERSTRIP ADHESIVE. Smells almost as good as that glue we used to use to make models back in the 60's till they banned it because some of the bad youngsters were sniffing it to get high. If you don't mind the BLACK part, give it a try, if you can get it over there, I am sure you will not be disappointed.
Fred Astaire, Ginger Rogers and Tommy Dorsey, eh? You forgot Glenn (Miller). ๐

Are you pretending to be naive again, mr. Ilett?
You shouldn't need a lightning bolt to test your protection. A switched relay or any other inductive load should yield hundreds if not thousands of volts for your TVS to clamp, as I'm sure you know.
And you're known to have both a video camera and an oscilloscope.
what about a epoxide resin coding for the PWM5 Femto?
Just curious – what's the benefit of using the UV glue over one of those small waterproof enclosures you can get from China fairly cheaply?
Very entertaining and pleasant video as always Julian. I do prefer to listen to a Brit or Aussie nerd. Yankees are too nasal. I should know – I am one. Also, I'm half Brit and half German. a wonder I don't hate myself, aye? btw… I think it's time for a bigger cutting mat there. Thanks!
Those bi-directional diodes are used in magnetically latched contactors to suppress back emf when applying a supply to the contactor coil in either direction ๐
