Check of system of shop
If you found defect in system of shop - defect of the generator can be the cause of any. Fill the following checks:
a) You watch priwodnoj to belts and you are convinced that it is intense it is not damaged. At detection of damages you replace it (address the head to Routine maintenance).
b) are convinced that bolts of strengthening of the generator of course are tightened;
c) Check the line of the generator and all plugs. All contacts of course, should not be okislennymi;
d) Check the corresponding protection devices which are located in motor office (address the head to the electric onboard equipment). At detection burning you delete the reason of peregoranija of the protection device and you replace it (at peregoranii of the corresponding protection device you cannot start the motor or accept some devices);
e) Start the motor and you are convinced that from the generator minor sounds (whistle or squeal cannot ring about defect of camps or sale of brushes) signal;
f) are convinced that the battery is invited completely. If one of cans is damaged, the battery can consume excess current;
g) Exclude tops of lines of the battery (at first negatively). You look at clips of the battery and top of lines. At detection of traces of corrosion you clean them (carefully address the head's materials for Routine maintenance). Connect tops of lines in clips and, of course, you tighten.
Measure effort on battery clips at the excluded motor. It has to be along with these 12 W.
Connect the voltmeter in poles of the battery and conduct the motor. Increase changes until the stable effort is not established. Statements of the voltmeter have to lie in borders 13.5 to 14.6 W.
Electric devices will accept it perhaps bigger (searchlights, the heater fan, heating of back glass, etc.) and are convinced of what the voltmeter 13 to 14 W.Naprjaschenije shows can fall, but again has to go (for this purpose to you, increase perhaps, it is necessary to increase a little change of the motor).
If the effort on the voltmeter passes the specified sizes, replace the effort regulator.
If the effort on the voltmeter is admissible below as much as possible, then worn-out brushes, weak feathers of brushes, failure of the regulator of effort, the burning-down diode, a slope can serve for the defect reason in a parcel, and also defect of rings of a collector. The condition of brushes and rings can be checked, but if nothing changes, the generator has to be accepted for conducting check, repair or compensation.
