Runleader RL-BI003 Battery fuel gauge is a Instrumentation that measures the remaining power by monitoring the voltage change of the equipment.
The display is dark.
I opened the instrument. I see a vaporised resistor. I think it had 1/4 Watts, but the colour code is no longer readable. I think this resistor was to messure the potential drop to trigger the LEDs.
Has anybody an idea what value the resistor had. In the moment I gauge 14 Ohms.
