Drop in going to direct drive

I am looking for suggestions. I installed a new driver in a Lumens Factory E-series drop-in and it worked well for a few minutes. I was able to try some of the different mode groups and everything seemed fine. When I was playing with mode selection, it switched to direct drive and I can't get programming back. I know it's not mode locked, because I took the top half of the bezel off and held the drop-in with my fingers and I could access programming again. I checked all my connections and points that need to be insulated, and everything seems fine. I am using an IMR 16650 battery. Thanks for any help or ideas

Did the volts in the battery drop to low. Below a certain level it might run direct drive

Nope. Battery is fully charged. Thanks for the speedy reply, though.

Ya that is pretty much the extent of my knowledge on this subject. Lol. Have you tried giving it a good wack?😂😂

No, but I have tried swearing. A lot!

I figured out the problem. The flat top battery was a little shorter, and the new bezel I got from Lumens Factory must place the tail of the spring just a little higher. All this produced an inconsistent connection that caused problems. When I put the drop-in in a different light, I could access programming mode. I switched batteries in the original light and everything works perfectly now!
