New Tool AA cycles through modes when turned on without touching the button. What am I doing wrong?
Tighten the head securely 
Clean as best as you can all contacts.
Try to bypass the switch with a paper clip and touch for all levels.
If the light goes well it is switch problem.
If the flashlight do the same is driver problem but before the paper clip try with the switch screwed in
did you repair it??? what was wrong???

You can try bypassing the switch using a paper clip. Touch the paper clip to all levels (if applicable). If the light behaves as expected, the issue might be with the switch. If the flashlight still cycles through modes, it could be a driver problem. Before using the paper clip, also test with the switch screwed in. uno online
