High Voltage reconnect | BMW i3 Forum

I am guessing that the OP eventually figured it out, but since no-one posted the correct answer here, and I just figured it out the hard way, I thought I would share what I learned. Like the OP, I could not get the disconnect slide to go back down until I realized that there is a latch clip on the left hand side that needs to be pulled out clear of the sliding part. In addition, the red tab at the top needs to be pulled up to its highest point (in case you pressed it down at all while getting the mechanism to reconnect). Once these two barriers were addressed, my sliding connector snapped back into place with ease.
