No power on MTN 17DDM driver

trailhunter · 2019-07-13T23:21:22.000Z

This is weird, two drivers so far and I’m not getting any power through them. I’m using a power supply to test. If I touch the + and - on the mcpcb, leds light up. If i alligator clip the power supply to the driver, no power.

Am I doing something wrong?

How about resizing that second pic to 100% wide?

There we go, apparently passing over _d as part of the resize actually resizes the photo

After the driver is hooked up, are you sure the LED’s aren’t on? First mode maybe ML, and with something like this driver on a triple, ML will be very very low.

Maybe you were sent a version with electronic switch firmware? Have you tried putting a switch on pin 2? I can’t remember if my eswitch version flashed the LEDs when connected to power.

Is the driver tight when the retainer ring is tightened?

. *We will be transitioning from1.2mm PCBs* to 1.6mm PCBs on the MTN-17DDm

The transition will happen as current 1.2mm stock runs out. This transitional period may take a few months

Did you solder that negative lead onto the FET? Or did you get the leads already installed?

I soldered the leads from the mcpcb.

Its tightened down. I also used a power supply and touched the leads directly to the drivers positive and ground and nothing.

I havent tried. Even if I tap the power supply leads, it wouldn’t switch?

Yeah definitely sure. Hmm what gives

I have had problems with the thinner boards (1.2mm PCB’s)not making ground, probably why he is going back to the 1.6mm boards, the retainer ring would bottom out and the driver felt tight but wouldn’t be tight enough to make ground.

Assemble everything outside the pill and see if it works….touch your power supply leads to the spring and ground ring on the driver momentarily to see if it works…

Maybe the FET is fried from too much heat?

Bummer, still nothing. I got 2 more drivers I’ll try them out. But 2 of 4 is kinda weird

Ok 3 of 4 dont work.

For what it is worth I have ordered 7 drivers from Richard and none of them were defective, there is something else wrong. Get a multimeter out and test the voltage to the microcontroller. If there is voltage to the microcontroller but not the pin that controls the FET then it is a firmware/switch issue.

This is an e-switch driver in this picture…

So I have ordered two of these drivers that came with a capacitor installed instead of the pads being bare, and no note. When I contacted Richard he said the capacitor helped with noise, this was last year some time.

Mine didnt come with that. This is what I ordered FET + 7135 Driver - 17mm - MTN-17DDm

Is this an e-switch driver? For now I put a v54 driver. Fricken light is pulling 12amps on high :zipper_mouth_face:

trailhunter · 2019-07-14T02:43:34.000Z

Crap guys, so thanks for narrowing it down. Apparently I ordered all the drivers with biscotti firmware. I should be able to reflash with guppy or other firmware right?

FML.
