While riding in the last couple of heavy storms, I got an error (flashing red triangle) on my 2015 FX. The error codes on the display were 0020 and 0028. From what I could find online, it sounds like some kind of high voltage short. Dangerous? The whole time it ran just fine and cleared by the time I got home, then charged and ran fine after that. So, could anyone give some advice on whether this is something to worry about and should I maybe add some additional waterproofing somewhere? (Don't ride in the rain? That's ridiculous!)

It's not a short as such, just a tiny high resistance voltage leak caused by the damp.
All my Zeros from my 2012 ZF9 through to to my 2015 SR have done it, with no notable harm.
I generally ignore it, and I ride everyday, all year round in the UK...
Also, and don't quote me on this, but I think the isolation is referring to a leakage to the frame in the bikes 12v system, not its 110v system.

Sometimes water gets behind the accessory charging port rubber boot (when loose) into the signal pins, causing this for me. But I have a DSR, not an FX. In any case, a little electrical insulating grease is worth applying to exposed connections.
The relevant section of the unofficial manual could use improvement:

The first thing to come to mind was that theres some place you need dielectric grease to stop this... but I cant remember where. lol
(so this is a useless post)

I really like your advice on this! [emoji28]

That's fine. I'm trying to figure out what to recommend in the manual and all the experts think it's obvious but don't realize the average person needs a very specific list to follow and check.

Was it the aux charging port (anderson connector)?

That would be one of them.
Off the top of my head I remember the charge port, the dash connector, the buttons behind the plugs in the battery module, the throttle and brake switch connectors and that plug for the DC-DC... but I know thats not the full list.

Water spray off the Rear tyre was a serious culprit on my 2013, when I filled in the space in the tail with a sheet of plastic, I seriously cut down the time it took for the isolation error to occur on that bike. However on my 2015 it made no difference.
So I wonder on the older bikes if the sevcon getting damp also was/is an issue.

I have heard (with specific numbers) that the threshold for declaring a short to ground became less sensitive to moisture from 2013 to the 2014+ models. I haven't verified that or or determined what might have precipitated it, but clearly some engineer thought about it.
