for Starter Every Time Liquid Filling we need add Soda
Sodium Carbonate or only Distilled water is Enough.

in LRS, the moving contact move towards the fixed contacts,
in water as per rpm feedback. Keeping normal water as
electrolyte will have high resistance value. So to increase
the conductivity of the electrolyte, salt sodium carbonate
is added in water.
