Note : It may take a couple of minutes of the engine running to reach these figures.
Follow the procedure below to help identify a possible fault.
• Check the condition of the fan belt - replace if necessary.
• Check the fan belt is not loose - tighten if necessary.
• Check the condition of the 12V battery - replace if necessary.
Test the Engine Dynamo System
If no AC volts can be measured replace the dynamo.
• Check the condition of the battery terminals and the connections on the starter motor (positive)
and the engine (negative).
• Check the condition of the battery leads - these should be flexible, if they feel stiff or rigid
replace.
Reference will be made using the DSE 3110 DC wiring diagram contained within this handbook.
Battery Charge Fault Finding Guide
Start the generator. Once the engine is up and running the DC voltage at the battery should measure
between 14.0 to 15.5V DC in normal operation.
The DC voltage measured directly at the battery while the generator is at standstill should be around 12.6V
DC.
The engine dynamo can be found to the left of the starter motor
and has the fan belt around it. There are two light blue wires -
Fig.10.
• If continuity is present, start the generator/engine and
measure the AC voltage between the light blue wires. This
should be around 34V AC when the engine is running at the
correct no-load speed of 52.5Hz (3150rpm).
• Check the stator coil of the dynamo - Disconnect the white
wires from the main engine loom labelled No.21 & 22 from the
two light blue wires at the dynamo.
Check for continuity between the light blue wires, if no
continuity is detected replace the dynamo.
