Start a fire? In the pouring rain?
As for the shock, three letters: RCD.
Or, if you're here in the States, GFI.

Hi Mike. As you probably know while Solectria still sort of exists as a
utility scale PV hardware company, Solectria-the-EV-manufacturer is long
gone. Their engineers who would have your answer are no doubt now scattered
to the winds.
If you haven't already, you might try posting your

I recently bought an Alltrax controller for my Elec-trac tractor. Like most
(all?) DC controllers, it has 3 high power terminals. In this case they're
B-, M-, and B+M+ (actually marked just B+ but described

diode(s).
So I'll connect it the way the manual says.

I recall some discussion years ago about fixed frequency 15kHz+ Curtis
controllers having trouble with current limiting on large, low inductance
