I got this same driver and I’m having a little trouble with it too. Any help would be appreciated.
I put it in a D26 dropin with an SST20 and a single CR123. I’m only getting one mode. My thought is it’s going direct drive. With a slightly used battery I get just under a half amp. That seems to match up with what direct drive would be. Any thoughts?
Here is a picture (I hope it shows up ok I have not posted a photo before).

Edit: Sorry if the photo is too big. I tried to make it not break the page.
You should probably make the image 100% wide.
Instructions are here:

Raccoon City, thanks for the advice and for your nice how-to. I did read it before hand and thought I had followed the instructions. I did put ‘100%’ in for the relative width size but still wound up with the above. I reread your instructions and reviewed my post but couldn’t see what I had done wrong. I left it alone, afraid I might mess it up more. I did the post on my phone, I don’t know if that matters.
Just edit the post text and change the link picture (width) percentage to something like 60% and save. It will reduce the pic size.
{width:100%}![]()
change to
{width:60%}![]()
Sorry, I can't get hardly anything done on my phone, so I don't know how to help you.
Thanks guys! I changed it to 60% like Moderator007 suggested. It looks fine on my phone now. Now if I can just get this driver figured out…
