Generator Speed Check
The generator should never be
operated at a speed of 3800 RPMs or greater.
A voltmeter set to read frequency (Hz) can be used to
test generator speed. When the engine is running at
1800 - 2200 RPMs, the generator should operate at 60
Hz. Make certain that the paver engine is running at
1800 - 2200 RPMs and the hydraulic temperature is at
normal operating levels.
Generator Capacitor
The generator capacitor controls and regulates voltage
while the machine operates. If the capacitor fails, the
voltage will drop below normal or no output at all. It is
located under the generator cover.
If experiencing a drop in voltage, replacing the capacitor
will help determine if the capacitor is at fault.
To perform this procedure:
1. Shut down the machine.
2. Detach the wires on top of the capacitor.
3. Remove the capacitor and replace with new one.
4. Reattach wires.
Dielectric Grease
Dielectric grease is a nonconductive, insulating
compound applied to electrical connectors. When
applied correctly, a high-quality dielectric grease
displaces debris and moisture in the connector. The
proper application of dielectric grease lls any gaps
between pins or in the connector which prevents debris
and moisture from creating corrosion of the electrical
components.
Equipment damage can occur if using
low-quality, incompatible dielectric grease.
If not applied or incorrectly applied, corrosion can result
that causes rapid increase in resistance, intermittent
connections, overheating, and a variety of electrical
problems. Numerous electrical issues throughout the
machine can be avoided by the proper application and
use of dielectric grease.
