I was thinking for all wired connectors [if possible] to use glued shrink wrap tubing. The glue is for waterproofing.
As for waterproofing the enclosure, not sure I can and STILL have access to it decently.
Also I have to think of space as well as it will be on the deck of the mobility scooter.
So not a lot of space there.
Was thinking of using thin plywood for the box itself.
And then varethaning the heck out of it.
I did this already for the outside protection of my air conditioner and it is doing great after a couple years or so.
Thing is though, it has to somehow be ventilated as well for heat removal during the summer.
Lots to consider.
Anyhow, thank you yet again Alan.
I sometimes feel like I am your special project LOL.
