I modded a cheap RAYZ zoomie with one of these drivers and a cheap chinese 3watt ir led i had laying around. The driver was ordered from Mountain Electronics with the NLITE standard firmware flashed. I am unable to access any mode other than high. Any ideas? Thanks from a noob!!

have you gone probing with your DMM for shorts from the led? you switch modes by rapid clicking on/off, are you saying that does not work?

One only mode usually means you have something shorted

Double check all connections and make sure the emitter solder points are grounding out

Correcty i click it on and do half clicks to switch modes with nothing happening just stays on hi. Youll have to excuse my newbness what would i look for and where would i check for shorts the body and pill are plastic on the flashlight.

tested the pads on the star and the driver no shorts. hmmmm. if i touch the ground ring on the driver and the first star i get a beep, that would indicate the first star is connected to the ground ring?

Yes, the first star is a dummy.

To be clear: you checked for a short between LED- and GND, right?

correct no shorts would the switch have anything to do with it? as long as half clicks turn off the light you should be able to switch through the modes?

Correct. Breaking the circuit temporarily is how modes are changed. It’s common to use a DMM in the 10A or 20A range to replace the tailcap. In that case a person simply taps one of the DMM leads in order to cycle modes.
