Lezyne 900XL - Won’t turn on

[The Ouzo]

Got it working again.

Took it apart last night. The little green LED stayed on the entire time. Then whilst I was trying to figure out how to dismantle the battery and circuit board I decided to give the circuit board a wipe with a baby wipe. 

Green LED goes out.

I test it, it works.

So I grabbed an alcohol wipe that I happen to have lying around, gave the circuit board a good wipe then sprayed a light layer of Q20 on it.

Gave it a test this morning and its 100%.
