Hey all, first post, first Bike, 2016 Rad Mini first Gen. It has been a Boat Bike all its life.

I've wanted a Rad since they started making them and was excited to have one offered to me.
Out of the deck locker it came, and "hmm. Thats funny. It started fine a month ago" they say.
I have it now on spec to debug it.

Symptoms:
Battery lights come on when on the charger, out of the Bike. No panel response when mounted.
The 5 and 20A fuses seem to have continuity on my cheap MM, but I've ordered new ones anyway.

I see a port on the side of the panel but don't see any utilities to access it online.
Is there a flowchart for debugging RadBikes or ways to do a basic diagnostic?

It's a tired little thing, with perished tyres and rusty bits. (why no SS bolts, jeez)
If there's a new battery or controller needed I'm not sure it makes sense.
What do the people who live inside my magic tablet say?

thanks in Advance, T
