I use same exact connections . Were you the one who emptied all the inventory off the shelf right before I got to store? At 1.99$ per connection I really can't blame you.
On my last trip to Lj my meter would not power up . So I start checking things knowing I have a brand new battery fully charged . That's when I discovered same exact problem you have . I did on the water repair to get me through the day . I really dispise electrical issues on water
. What do you guys use to make electrical connections ? Barrel connectors ? Or screw on connectors with some sealant ?
