XB-500 Controller Wiring
I'm posting a picture of the XB-500 Controller and the wiring as what I know or believe to be true. Please help me identify the wires and connectors if you know where they go. ? Next to ones I am not sure about. Feel free to copy this and/or edit. Hopefully once it's correct and verified it will help someone else later.
From Right to Left
[Right Side Group]
White Single = ?
Red Single = Positive input from battery
Black Single = Negative input from battery
Blue Single = To motor
Green Single = To motor
Yellow Single = To motor
White 6 Connector = Motor Hall Sensor (6 connector but only 5 wires)
[Left Side Group]
White 3 Connector = ? (Brown Blue Black)
Red 3 Connector = ? Throttle (Red Black Green)
White 3 Connector = ? E-Brakes (Orange Yellow Black)
White 2 Connector = ? Speedometer (Orange Blue)
Somewhere on this board, there is a link to an entire XB-600 schematic, but I can't find it right now. Here is a section of that schematic that I clipped out and posted for another question. It shows the color of the wires, which look to be the same as your photo above. Ignore the red circle;
I hope this helps,
Here is the link to the xb-600 wiring diagram
The single white wire is for the speedometer.
maybe the "Orange Yellow Black" connector did not go anywhere. On my xb-600 controller there are connectors that are not on the plan. I don't know what they are for.
Some controllers have a purple wire (not white) for the speedometer.
I don't think the (Orange Yellow Black) plug is for brake lights. Normally all lights are fed by the 48v/12v converter.
On the plan you can see the two diodes in parallel connected to the brake light. It's probably the same for Xb-500.
Nice project you got there !
good luck !
Well I just wanted to thank everyone for contributing on this. I succesfully installed a new Infineon controller in the scooter this weekend and took it out for a test run this morning. It runs great and is only running on the original stock batteries thus far. The only thing I was unable to get working so far is the speedometer.
I installed a 72 Volt – 45 Amp Infineon controller that can run any voltage between 27v and 90v. It also has a variable LVC. I plan to go to 60volts tommorow. . . .
Where'd you buy it? How does it do on hills?
4 months ago, I also got to push The Beast 1/4 mile with a locked wheel. If I knew then...
Tip in case there's a next time: make sure you have a tool kit on board, especially a Phillips head screw driver. If you run into a problem like this again, disconnect the battery and then disconnect the controller and your wheel will unlock. Another secret, if you can do something with your battery box (have someone come pick it up or leave it at a neighbor's house), the scooter actually sorta rides much more like a bike minus the 40+ pounds of battery. Even if you don't pedal it, it's much easier to push that way.

Before I did the Shunt Mod on my XB500, I measured the maximum battery current on my XB500 while going up a 14% grade and coming to a complete stall. The max current was 15 amps, which translates to 720 watts. (48V * 15A). After doing a shunt mod by adding a 2.3 inch piece of steel 16 gage wire to the already existing shunt, my max current was 24.8 amps, and my bike did not stall on the 14% grade, but did slow down to 5mph with a 170 pound load. I used my current and voltage measurements to determine how much resistance I needed for my shunt mod, without pushing the current limit so high that it would melt my wiring or blow my fuse. My shunt mod instructions are posted on my website at:
When you get there, click on the tab "More Power". My website also contains a bit of additional technical info that you might find handy.
Just wanted to send a big THANK YOU your way for posting your wiring results for your controller. It saved me BIG time when I had to reconnect mine.
I would like to know if its possble to plug only the Motor and the wiring for the sensors, The speed adjust holder, the batteries (72v) and the power switch with the stock Controller with the shunt mod and the 72v mod ? Thanks
Is the E-brake slow tne motor ? or is just a system to avoid trottle input when you brake ?
I have a question about my xb-500. I want to do the 60v mod to my bike so I took the front panel off to see if the controller and the other box said 64V on it and it says nothing on either box. So should I still do it or not take the chance?
