With voltmeter , check the battery voltage at the base and battery pack. Then check the voltage at the basket , where the battery light is. Is battery voltage same. If not , wire harness has bad connection or damaged wires. Check the wires from basket, to the lower connection points and see if there is a corroded terminal , search why the voltage is lost.

I can eliminate the cable going to the basket by plugging the control panel directly at the base unit. But there is no change in the low battery warning.

What is the battery voltage with meter test.
Customer: replied 12 months ago.
12V
Expert:  Curtis B. replied 12 months ago.
With test meter?
Customer: replied 12 months ago.
Yes with my multimeter
Customer: replied 12 months ago.
It is actualy 12.7 when the motor is running.
Expert:  Curtis B. replied 12 months ago.
Fully charged 12 volt battery should be over 13 volts. With 12 volts, battery is very low. Does it drop if you use any function?
Expert:  Curtis B. replied 12 months ago.
With control plugged in at the bottom, what is voltage inside the panel?
Customer: replied 12 months ago.
It won't let any operation happen with a low battery warning. Even though the main controls show a full charge on the battery
Customer: replied 12 months ago.
Where would I take that voltage reading at the panel?
Expert:  Curtis B. replied 12 months ago.
I agree, that's why you need to check the voltage at the idiot light.
Customer: replied 12 months ago.
It only takes 5V to turn the idiot light on.
Expert:  Curtis B. replied 12 months ago.
And what is the voltage??
Customer: replied 12 months ago.
Because the light is flashing there is a pulse of 5V
Expert:  Curtis B. replied 12 months ago.
Follow the wire back and find where the voltage has dropped.
Customer: replied 12 months ago.
It is a multi level circuit board. There is no way for me to trace it.
Expert:  Curtis B. replied 12 months ago.
Try unplugging the circuit bards and reinstalling them, the next choice is to buy new boards!
