store the spare electricity produced by the generator. While the engine doesn't work or run at
low speed, the stored electrical energy can supply electricity for all of the electrical devices
and to start the tractor. While the engine overloads in a short time, the battery can help to
supply electricity. In routine use, the battery should be often checked and maintained in
accordance with the technical maintenance regulations of the tractor.
A. Before using the new battery, fill the electrolyte stipulated in table 2-4 to the required
height, then keep the battery for 15 minutes, after that, the battery can be used; after starting
the engine, firstly it is better to charge the battery for 1-2 hours, which is good to extend the
service life of the battery.
B. Dust and dirt on the outside of the battery should be often cleared away in case
electricity leaks. Check to see whether the battery has crackle and electrolyte leak; keep the
terminals and all contacts in good connecting condition; keep the air hole on the plastic cover
unblocked, so as to protect the battery from explosion because of too much gas in the battery.
C. Check the height of electrolyte level and specific gravity. In normal use, if the height
of electrolyte level is below 10-15mm, distilled water should be poured into it in time. Well
water or river water can't be used. So as to prevent impurity from entering electrolyte. If
electrolyte overflows much under unusual conditions, it can be added. The density of
electrolyte in electrolytic cell should be not lower than 1.2g/cm3; if the density is too low, the
battery should be charged in time.
D.The time of continuous starting should not be more than 10 seconds in case
overdischarge. The battery should be charged at regular interval. The single voltage of the
charged battery should be 2-2. 1 V.

2) Use of generator and regulator
A. Generator should be used with regulator.
B. The generator is connected with ground by negative pole. The generator is connected
with the regulator and the battery by negative pole. The positive and negative poles of
generator, relay and battery can not be connected in wrong way. Otherwise the generator and
regulator may be damaged.
C. Checking the generator by short circuit is prohibited. Megaohmmeter or A.C. power
