A simple motorcycle battery over discharge protector circuit is explained in the following post. The circuit will prevent the battery from overdischarging by the motorcycle headlamp whenever the mo-bike alternator is not enabled or is idling in the neutral mode in which case the battery is normally subjected to excess loads via the headlamp bulb.

The circuit idea presented here shows a simple method by which insufficient water conditions inside an underground tank can be sensed without introducing probes inside the underground tank, and thus preventing any possibility of motor dry running. The circuit also incorporates an overhead water overflow control feature. The idea was requested by one of the interested readers of this blog.
