Yup ^^^.
I've done all the usual, shorting a couple of LiFePO4 cells with an uninsulated spanner (large roll of heat shrink acquired), getting hold of both ends of a panel string (panels come up to voltage very quickly with even small amounts of light) etc. etc.
I admit that just last week, I managed to cable a string and got +ve coming out of the black wire (luckily, I'm paranoid about checking polarity, again and again).
