Brian Posted January 22, 2016 Report Share Posted January 22, 2016 Hey guys, I'm having a problem with a block 21 smqv. It is eating batteries at an alarming rate. It's been talked about before but I cannot find the thread. any help to remedy the problem would be appreciated. b Quote Link to comment Share on other sites More sharing options...
Sound Art Film Posted January 22, 2016 Report Share Posted January 22, 2016 Apply super secret silver lectro paste to thumbscrew. More than likely, that's the culprit (high resistance). :-) Quote Link to comment Share on other sites More sharing options...
afewmoreyears Posted January 22, 2016 Report Share Posted January 22, 2016 Call Lectro, ask for a silver paste kit... Then make sure you have the new generation thumb screw (larger and darker in color) and NEW STYLE wire mesh crush washer... if you do not have these, ask if you can obtain one of those kits as well... From Memory... sorry... Unscrew the old thumb screw, Remove cir clip and remove old thumb screw.. put aside both you may need the Cir clip again, not the thumbscrew. ,clean the female side of the threads on the unit well with a clean rag or other device... Continue to wipe threads until rag or other device is clean.. Place new screen type mesh washer onto the new thumb screw, put screw through back of battery lid. replace cir clip. Place a very small dab of the silver paste on the male threads of your new thumb screw, put lid back on unit, screw in and out a time or two.... Problem SHOULD be solved.

Derek H Posted January 23, 2016 Report Share Posted January 23, 2016 Also, clean the threads. Yes, get the new screw kit, it's free, but just cleaning it might help quite a bit. Quote Link to comment Share on other sites More sharing options...
Brian Posted January 24, 2016 Author Report Share Posted January 24, 2016 Thank you gentleman, i will contact lectro for the paste and new thumb screw kits. I'll clean out the threads in the meantime Quote Link to comment Share on other sites More sharing options...
Brian Posted January 25, 2016 Author Report Share Posted January 25, 2016 just cleaned both off my SMQV's nothing happened. Tried swapping battery compartments between the two... and now the battery life is back to normal. I'm still contacting Lectro to get the new doors but for now I have my transmitter working again.

Switching the battery doors puts additional force on the threads since the two different compartments will have worn a little differently. This is perfectly OK but will only last until the "new" threads wear together. It is still a good temporary solution and not one most people would come up with, such as me. The silver paste is a better solution and will last 6 months or so. Silver paste plus the new doors is a pretty permanent solution and is free.

old school Posted January 25, 2016 Report Share Posted January 25, 2016 I just ran into this issue with my 2 new block 20 transmitters... I thought my batteries were the issue. Now I need to find the box I put away with the Silver Paste. Thanks. CrewC Quote Link to comment Share on other sites More sharing options...
LarryF Posted January 25, 2016 Report Share Posted January 25, 2016 Units made in the last several years shouldn't have this problem. If they are newish, something else is afoot. Best, Larry F Quote Link to comment Share on other sites More sharing options...
