Check Output Voltage to LCD Display
The secondary function of the motor controller is to provide 5vdc power the Cycle Analyst LCD Display.
Using a digital multimeter VOM, measure the voltage on pins 1 & 2 of the CA-DP connector coming from the motor controller. There should be +5vdc across these two pins.
⚠️ Make sure the controller is powered on.
❗️ Do not short these pins during the measuring process!
- Is the Controller providing voltage on pins 1 & 2?
Yes - (Normal) Replace Cycle Analyst LCD Display
No - (Abnormal) Replace Controller
If the +5vdc voltage is present and the LCD display is not operating, replace the Cycle Analyst.
If the +5vdc voltage is not present, it appears there is a problem with the motor controller's low voltage output and it should be replaced.
