Generator Failure

Fig. 7.5.5-1: Coilplan
If a pass (beep) should be determined, the generator must be returned for examination in the plant, or it can also be
wound again locally. For this coil datas can be requested.
7.5.6 Measuring the inductive resistance
Unfortunately the checking of the ohmic resistance permits still no reliable statement about the condition of the coil.
If the ohmic resistance values arise inequalities between the coils, that is a safe indication for the fact that the coil is
defective. To be exactly sure the inductive resistance of the coil have to be measured. For this a special measuring
instrument is necessary, which measures the inductance of a coil.
Inductance is measured in the same way as the ohmic resistance, i.e. the coils are compared. The value is indicated
in mH (milli Henry).
The arranging value for the inductive resistance can take from the Table 8.2.1, “Technical Data Generator 4000s SC
+ FC,” on Page 124.
Note: These values depends strongly from the measuring method (kind of the measuring instrument)
7.6 Starting Problems
7.6.1 Fuel Solenoid Valve
The fuel solenoid valve is located in front of the injection pump. It opens automatically, if the „START“-button is pres-
sed on remote control panel. If the generator is switched to "OFF", the solenoid valve closes. It takes some seconds,
before the generator stops.
If the generator fails to start, runs rough, does not reach the proper RPM, or does not stop properly, the first item to
suspect in most cases is the fuel solenoid valve and should be inspected first.
A check of the fuel solenoid valve by removing the plug from the fuel solenoid valve for a short period whilst in ope-
ration (first remove the small retention screw) and replace it immediately. The motor should "react immediately" by
revving high. If the motor does not react sharply to the reconnection of the solenoid wire, it is a sign that the solenoid
valve could be faulty.
