The charger that came with my TCMax failed a couple of months ago.
It stopped charging and went into the red/green LED flashing mode.
I could hear a quiet click every few seconds like a small relay operating.
It was out of warranty so I started looking for alternatives.
I found and followed these excellent instructions https://titimus.co.uk/super-soco/charging so now I have a cheaper, faster, (but much noisier!) replacement.
This evening I took the old one to bits.
Inside it is completely "potted" https://en.wikipedia.org/wiki/Potting_%28electronics%29
Even the heatsinks are surrounded by the stuff, and not in contact with the case.
I hope the compound was thermally conductive!
It was quite crumbly and brittle so I spent an hour removing as much as I could, revealing the internals.
@mrj How many wires from the super soco side are connected looks like a few are cut off and 1 goes to the negative
Are you Miktheyob on reddit? they had same charger, this isn't an official charger and is fake.

That grey stuff is to give the charger more weight to make it feel more expensive. My Charger has none of that grey stuff in.
@lostit No that's not me. Looks like they're in Australia. I'm in the UK.
My charger is genuine. It came with the bike, which was brand new, from a dealer 3 years ago. No doubt they revised the design / manufacturing.
The potting compound (the grey stuff) was light and rubbery, and compared to the heavy weight of the aluminium case, you wouldn't notice the extra weight. So I don't think its there to add weight. Usually electronics are potted to make them waterproof or provide mechanical security: there were several flimsy circuit boards sticking up from the main board, and potting the whole lot is an easy way of securing them.
Ain't so much repairs you can do on a charger. It could be a faulty connection on one of the wires from the charge connector to the charger that is causing the condition of blinking red and green. That's what I know in general but I don't know specifically on Super Soco chargers.
