A device for indicating the rate of charge in an AC generator with a contactless type voltage regulator having an exciting diode for supplying electric current to a field coil of the AC generator. The device includes a relay coil connected to an output end of the exciting diode, a relay contact responsive to an excitation of the relay coil and a charge warning means responsive to the relay contact thereby preventing malfunction of the charge warning means.

DETAILED DESCRIPTION Accordingly, it is a general object of the present invention to obviate the disadvantages of the prior art devices described above.
It is another object of the present invention to provide a device for indicating the rate of charge in an AC generator which does not give ambiguous indications of the rate of charge.
It is yet another object of the present invention to provide a device for indicating the rate of charge capable of supplying a ground to various electrical components when the ignition switch is on.
It is further object of the present invention to provide a device for indicating the rate of charge in an AC generator capable of supplying a ground to various electrical components even when the ignition switch is off.
In keeping with the principles of the present invention, the objects are accomplished by a unique device for indicating the rate of charge in an AC generator with a contactless type voltage regulator having an exciting diode for supplying electric current to a field coil of the AC generator.
The device includes a relay coil connected to an output end of the exciting diode, a relay contact responsive to excitation of the relay coil and a charge warning means connected to a battery via the relay contact.
In one preferred embodiment of the device for indicating the rate of charge in an AC generator, the relay contact is a normally open contact and in another embodiment the relay contact is a normally closed contact.
