the voltage regulator becomes either highly inef?cient or

always possible to promptly replace the regulator by a
new one, nor is it possible in many instances to repair
the same inasmuch as such repair requires highly skilled
labor without which the electrical system as a whole
could possibly sustain serious damage.
The present invention avoids the dit?culties above out
lined by the provision of emergency repair means whereby
defective points of the voltage regulator may be electrically
by-passed to permit satisfactory function of the system
until a permanent repair can be effected, such repair
means being extremely simple both in structure and in
result in a serious damage of the system as a whole.
The present invention permits an emergency repair to
be made without any tools and with marked expediency
even by unskilled persons, as will be presently apparent.
In accordance with the invention there is provided a
