I'm started to get tired of using the kick in my ts. To many connection problems.
Thoroughly clean the inside of the GGTS tube
Clean and add a bit of tension to the Kick's negative contact spring so it makes solid contact to GGTS tube
.....that's where connection issues occur and should solve your problem
Mounting the DNA 12 isn't rocket science; just have to be careful of it's placement in the tube...there is no room for error for the delrin disks that hold the + contacts on each end. You lose the floating center pin function, but that's no big deal since your battery will probably be an 18500.
I want to use the onboard +/- watt adjustment buttons with the DNA20 so that's gonna take a bit of rigging. Another plus for that board is an auto power down when not in use. I really like the battery gauge since I always leave the house with, what I think, is a charged battery, but it dies when I'm a couple of miles down the road. lol
All in all it's a pretty neat electronic gizmo
