GENERAL<br />
<strong>This</strong> manual <strong>contains</strong> troubleshooting and repair<br />
procedures for the YD generators and controls..<br />
Engine information is in the applicable engine man-<br />
ual. Three systems which could cause the electric<br />
generating set to malfunction are the generator, the<br />
control and the engine.<br />
The YD generator information includes description,<br />
troubleshooting, adjustments and tests for repairing<br />
the generator, exciter and voltage regulator.<br />
The majorsection of this manual applies to most, but<br />
not all, YD generators. In the development of larger<br />
capacity generators in the YD family, Onan has<br />
included some modifications so that the generator<br />
would have adequate motor-starting capability.<br />
These modificationsinvolve two basic areas:<br />
1. The rotating exciter (rotor and stator) is about 112<br />
inch thicker than standard. <strong>This</strong> results in the<br />

winding resistances being different from the<br />
majority of generators.<br />
2. The "UR" regulation system is used rather than<br />
the standard YD regulator.<br />
The generator set models affected by the above mod-<br />
ifications include:<br />
25 kW MDTNDTA'generator sets<br />
30 kW SK generator sets<br />
30 kW YD PTO generators . '<br />
Separate sections of this manual should be referred<br />
to for information on these models which is different<br />
from that provided in the main body of the manual.<br />
The Controlsystem informatipn includes description<br />
and troubleshooting procedures for repairing the set<br />
if the trouble is in starting, stopping, or if thesetshuts<br />
down because of an emergency condition.<br />
