You’ll need to get a new switch.
OMG, you're right on! I'd never thought of bad switch.:thinking:
Since I have most if not all of Tain's creations, I thought I would just took the other tail switch to try. But this one has different tail switch buried inside with no tail cap!
Out come the good old alligator clip test wire and BAMP all is good.
Now only if I figure the way to remove the the brass retainer ring with 2 tiny holes for removal and the switch supplier, all will be okay.
I may have to fashion a custom tool for this job :thinking:
Snap ring pliers are perfect but longer needle nose usually does the trick
