Heated Glass Element: Description and Operation

GENERAL INFORMATION
The system consists of a rear glass with two vertical bus bars and a series of electrically connected grid lines baked on the inside surface. A control switch and a timer relay combined into a single assembly is used on all models.


Circuit protection is provided by a fusible link, located in the charging circuit, for the heated grid circuit and by a fuse for the relay control circuit.

When the switch is turned to the ON position, current is directed to the rear defogger grid lines. The heated grid lines in turn heat the rear glass to clear the surface of fog or frost.

CAUTION: Since grid lines can be damaged or scraped OFF with sharp Instruments, care should be taken in cleaning glass or removing foreign materials, decals or stickers. Normal glass cleaning solvents or hot water used with rags or toweling is recommended.
