Troubleshooting And Adjustment; For The Bc Generator - Westerbeke 9.0 BCG Technical Manual

TROUBLESHOOTING AND ADJUSTMENTS FOR THE Be GENERATOR
The following trouble shooting guide is designed to give insight into problems which may be encountered
with the BCG 4.0KW and the BCG 6.5KW Westerbeke brushless generators. Owing to the simplicity of the
equipment and controls, troubleshooting is relatively easy, once the relationship between cause and effect
is understood.
Most potential problems are covered in this guide; however, should an omission or an error be found, we
would greatly appreciate your notifying us of it.
Keep in mind that a basic, fundamental knowledge of electricity is required for this troubleshooting, and al-
ways remember that lethal voltages are present in the circuitry; therefore, extreme caution is essential when
working on or troubleshooting a generator.
Only a few basic tools are necessary for diagnosis and repair. These are hand tools: an amp-probe and a
quality volt-ohmmeter capable of reading less than one ohm due to the precision required in reading com-
ponent winding resistances.
NOTE: Do not always rely on the vessel's instruments for accurate readings; try to bring your
own.
Before attempting any repairs, get as clear an explanation of the problem as possible, preferably from an in-
dividual witnessing the problem. In some cases, this may bring to light a problem which is related to the
method of operation rather than equipment fault.
Bring basic repair parts with you on the initial trip to the problem equipment, such as a regulator board when
installed, diodes and bridge rectifier, so if the problem should be found in one of these easily replaceable
parts, the problem can be remedied early and efficiently.
The internal and external wiring diagrams are important tools in troubleshooting this generator or any gen-
erator model.
