Testing.
Start and operate generator set at rated voltage and frequency.
Apply some load to generator set.
Release control panel by turning two fasteners and lower control panel slowly.
Set multimeter for AC volts and take readings between terminals VI and N1, V2 and N2, and V3 and N3. Multi-
meter indication should be 120 VAC between each set of terminals.
Take readings between terminals S1 and-, S2 and –, S3 -, and LI and -, L2 and -, and L3 –, and Multimeter
indication should be 0.1 to 3 VAC (reading will vary depending on amount of load applied to generator set).
Change multimeter setting to DC millivolts and take reading between terminals + and -. Multimeter indication
should be 0.1 to 50 mv (dependent on amount of load applied to generator set).
Shut down generator set.
Replace kilowatt transducer if multimeter indications are within ranges stated in steps d and e, but not within
range stated in step f.
If no repair is needed, raise and secure control panel.
Removal.
Shut down generator set.
Open battery access door and disconnect negative battery cable.
Remove control box top panel, paragraph 2–1 5.1.
Tag and disconnect kilowatt transducer (40, FIGURE 2-14) electrical leads.
Remove screws (39) and kilowatt transducer (40).
Installation.
Install kilowatt transducer (40, FIGURE 2-1 4) with screws (39).
Connect electrical leads and remove tags.
Install control box top panel, paragraph 2–15.4.
Connect negative battery cable. Close battery access door.

Inspection.
Shut down generator set.
Inspect shunt for cracked casing, burned or broken terminals, and other damage.
Testing.
Shut down generator set.
Open battery access door and disconnect negative battery cable.
Remove control box top paneI, paragraph 2-15.1.
Tag and disconnect shunt (43, FIGURE 2-1 4) electrical leads.
Set multimeter for ohms and connect to shunt terminals 1 and 4. Multimeter should indicate less than 0.5 ohms.
Replace shunt if multimeter indication is greater than above.
If no repair is needed, connect electrical leads to shunt (43) and remove tags.
Install control box top panel, paragraph 2-15.4.
Connect negative battery cable. Close battery access door.
