I Nuked my BGX

uLight,


This is the back of the display on the handle bars. The display and the uLight are parallel so you can connect to either or. But one difference is the uLight has a couple of 12v outputs.

This is where I'm at. I'm waiting for a julet plug for my headlight. That's going to allow me to use the stock wiring harness. I expect that to cut down on the final soldering quite a bit.

I finally got the last part I was waiting for, so now I can finish hooking up the rest of the controls, and lights. I think I'm on top of the rest of the wiring, throttle, brake cutouts, kill switch, and lights. The part I'm dreading is the set up. The set up manual is 30 pages, half of which I barely understand what they're talking about. I did find evidence I can operate my brake light if I can figure out how to enable it.

I'm guessing PWM P1, and P2 are 101, 102.


From here on it should get more interesting.

Today I made this wiring harness to connect my stock wiring to the uLight.

Just remember you need an isolated power supply for the uLight if you use one because your lights draw more than the 3a or whatever its max is. I have used a regular 12v wall adapter 110vac right on the 72v for years even before my time with a nuc.

The total power consumption for my headlight and taillight combined should be about 1 amp or less. They're both LED, and I'm not running the day time driving light. I'm assuming the uLight can handle that, so I wasn't planning on needing a converter. I'm also assuming the uLight is protected for over current, so I didn't add an inline fuse for the lights.

There's still time for me to make changes. If I'm fixing to ride off a cliff, someone stop me before it's too late.

I've finally soldered myself out of a job. It's all over but the programing. Lord help me.
