7.2.3. Check of falling of output tension of the generator

This check is necessary for assessment of a condition of conducting from a conclusion "In" the generator to the plug (+) the rechargeable battery (including a fusible insert).

Preparation for check
1. Transfer an ignition lock key to the provision of "OFF".

NOTE
For exact definition of malfunction of places of connections be convinced that when performing check both conclusions or their connections are not disturbed.

2. Connect the digital voltmeter to a conclusion "In" the generator and the plug (+) the rechargeable battery. Connect a wire (+) the voltmeter to a conclusion "In" the generator, and a wire (–) of the voltmeter – to the plug (+) the rechargeable battery.

Conditions of conducting check
Read out indications of the voltmeter at the idling engine and the included load of the generator (headlights of head light, the heater fan, etc.).

Analysis of results
Normal the voltmeter has to show the rated voltage of 0,3 Century.
If power failure more than 0,3 in, then, most likely, is the reason defect of conducting.

Fig. 7.10. Scheme of check of conducting of the generator


Check conducting from a conclusion "In" the generator through a fusible insert to the plug (+) the rechargeable battery (fig. 7.10).
Check a condition of isolation of wires (lack of traces of an overheat) and contact in sockets. Eliminate defects, then repeat check.
After completion of check switch off everything consumers (headlights of head light, the heater fan, etc.), then switch off ignition.
