Folding generator test procedure


The first step: Check the generator wire connection parts with or without disconnection, wrong, short circuit phenomenon, and use a voltmeter to measure whether the battery voltage B + point.

The second step: the key door down "open" position, but do not start the engine, then use a voltmeter to measure whether the voltage D + point, and observe the charging indicator is bright.

The third step: start the engine, with a voltmeter to measure the engine B + point voltage, should reach the following values

12V system voltage of 13V or more at the same time add and subtract throttle, voltage

24V system voltage is 27V or more a little change 0.1 ~ 0.2V

Step 4: Open part of the load, such as lights

12V system voltage of 13V or more at the same time add and subtract throttle, voltage

24V system voltage is more than 27V medium change 0.2 ~ 0.4V

The fifth step: open air conditioning, lights and other major electrical appliances

12V system voltage of 13V or more at the same time add and subtract throttle, voltage

24V system voltage of 27V or more have a greater degree of change 0.5 ~ 1V

In the third step, the generator does not have the voltage output, can take the following way to check, for the generation of excitation D + point of the generator, such as 27 series, 23 series, 29 series, 19 series from the battery positive lead a 2.5mm2 wire , Start the engine, with the other end of the moment click on the D + point (time 1S or less), and then use the voltmeter to measure the B + point voltage output, if any, from the third step to check the fifth step, and determine the vehicle charge Indicator light circuit has broken phenomenon (usually light is damaged, the instrument disc rod loose, line circuit), if no voltage output, the generator there is no power failure.
