QLITE 105c Zener - no modes?

I purchased a Qlite 105C with a zener mod, Nlite firmware and 4 additional 7135 chips, I’m running it in a Convoy S5 with a MT-G2. It turns on and off, but I cannot change the modes. A half press just acts like a soft-off button, but it always comes on at the same brightness. I have stars 2, 3 and 4 soldered, which should theoretically mean it’s set to descend from high, have no memory and have moonlight mode but it didn’t work prior to playing with the stars. Right now all I get is what I think is 100%, and that is it.

Any ideas? I purchased this driver from mtnelectronics months ago but only just hooked it up.

You have a short somewher, try your driver out of the host first

No joy, took it out of the host and got the same result.

Look for a little whisker of solder from the top of the board down along the wire, grounding it to the side notch exposed aluminum or copper, then to the back of the board, then to the pill.

It can be microscopic. It routes around the driver so the power is going directly through the LED to the pill.

It’s a really familiar problem.

Doesn’t appear to be anything amiss on the positive or negative terminals coming from the LED. Duff driver?

What current are you getting from the battery in the single mode? It may tell us if the short is between led- and gnd or pwm and B+ or if the driver is just wonky. Led+ wire is sometimes located very close to a pwm signal pad and a hair wire short can fix the driver in high. A short between led- and ground will fix the driver in DD.

Unfortunately I wasn’t able to test with my multimeter. The pill and LED rolled off my bench and hit the floor, which somehow made it work. I’d love to know what the issue was, but I suspect it was what you suggested and I’d simply missed it. Thanks for your help though.

Cheaper to just roll them off the table yourself. .

You’re too tall, you need lower tables.
