The red wire should be at the battery voltage. The blue wire should be 0V until it's connected to the red wire then it should be at the battery voltage as well
Damn. Guessing the controller is DOA. I dont see anything fried on the board, but all the red/black pairs are dead or very low. Any way to fix this?
The one with the white wire sounds like the hall sensor connector and the white wire is for a speed sensor built into the motor. The photo you've marked "Controller cable" looks to be for the display.
Yeah, the hall sensor wires were bundled in the same cable as the phase wires. I have them in terminal blocks since I was planning on sorting through the hall/ phase wires tonight.
Remember I said to keep the negative probe on the power input while making these measurements. So you are measuring between Gnd and the blue wire.
Ok, I got it. Again, no voltage.
You can google them, the pinouts will be near the top of the datasheet. They are linear regulators to drop the voltage (to 15V and 5V respectively). The 317T is a TO-220 and the 78L05 a TO-92 package (google those too).
Ok, I checked all 3 legs of the 317T, no voltage.
