Connect
щуп the voltmeter in the centre of each conductor of a heater of back glass. If the voltmeter shows pressure nearby 5,5 In, the heater conductor means is serviceable. If the voltmeter shows pressure 0 in or 12 In, means, there is a rupture of a conductor of a heater (
fig. 15.45).

For detection of a place of rupture of a conductor of a heater connect one
щуп the voltmeter to the positive plug of a heater, and the second
щуп move on a heater conductor from outside the negative plug of a heater. The point in which the pressure shown by the voltmeter, will fall about several volt to zero, will be is a place of rupture of a conductor of a heater (
fig. 15.46).
Before heater repair include it for some minutes.
Repair of a heater of back glass make as follows:
Restore rupture, using the special repair complete set.
Smooth out conductors from two parties from rupture of a conductor and degrease them.
With sticky tape stick glass from two parties of a conductor in a place of its rupture.
Prepare glutinous current-carrying structure from the repair complete set.
Put glutinous current-carrying structure to the place of rupture and the intact areas of each conductor on distance of 18 mm.
Dry up glutinous current-carrying structure during 24 ч then remove a sticky tape.
