One of the 4 shades in our sunroom was getting very slow to go up and as it inched up this morning I made a note to change them out while it was up since it's real PITA to do if they die with the shade down. I swear I replace the batteries in this one shade, the same size as 2 others in the room, and all of them 1/3 the side of the big one which has 2 battery wands, each with 8 Li AAs.
Anyway since I've practiced this often, I had the old batteries out and new ones in place in 5 minutes. Plugged everything and NOTHING.
- OK Dumbazz, did you put the batteries in wrong? Checked that out, nope all good.
- Is the connection good? Checked that out, yup all good
- Take the batteries out again and reload, making sure that you really tighten everything!! Roger that, still not working.
- Is one of those batteries dead? Out comes the volt meter, nope all good.
- Is the wand a problem? Reloaded the validated good batteries, plugged them into a working "sister ship" blind and BUPKIS!!
- OK, WTF is wrong the wand? Test the out going connection, no voltage, should be > 12V.
- Is it the bottom, ground connection, what you open to put the batteries in? Took top connection off, which has the wire, put the batteries in and NO VOLTAGE, so the bottom connection was FUBAR
- OK, why is it FUBAR? Messed around with it for a while, took it apart and reassembled, thought I got it to make better connection, but when reattaching to the tube, no voltage.
- Now I'm pissed, and broke out the duct tape. Instead of screwing down the cathode plate, I pulled the guts out of the screw cap, and duct taped them in place, using the top (anode) screwcap to load batteries. Put the volt meter on it and BINGO
- With heavy swearing, I attached it to the shade and SUCCESS, so now it's Whisky time...
