Check of serviceability of functioning and regenerative repair of a heater of back glass

Preventions in the beginning see Check of serviceability of functioning and replacement of the breaker of indexes of turns/alarm systems and the switch of last Has undressed.

PERFORMANCE ORDER

1. The working element of a heater of back glass represents a horizontal lattice from the current-carrying threads pasted on an internal surface has flown down. Heater activation is made by means of the switch located on the panel of devices of the car. Check up serviceability of functioning of the switch (the Section Check of serviceability of functioning and replacement of the switch of heating of back glass see).
2. Small breakages of current-carrying threads of a lattice of a working element of a heater can be eliminated without dismantle of back glass.

Check

PERFORMANCE ORDER

1. Include ignition and a heater of back glass. Press positive щуп the voltmeter to the positive plug of a lattice of a heating element, negative щуп press to the grounding plug. The device should register pressure of the battery, otherwise check up a condition of a safety lock, the switch and connecting electroconducting. If pressure in norm, however, a heater part does not work. Pass to a following stage of check.

2. To measure pressure during described below checks wind positive щуп the voltmeter with a metal foil which will be easy for pressing a finger directly to токопроводной threads of a lattice of a heating element (address to an accompanying illustration). Negative щуп a measuring instrument connect to the plug of grounding of a lattice.

3. Measure pressure in the central part of each of lattice threads. The indication in 5 – 6 In testifies to serviceability of a condition of a thread. The zero indication speaks about breakage presence between the centre of a thread and an element positive side. Indication overestimate twice (10 – 12) occurs in the presence of breakage between the centre of a thread and an element negative side. Serially check up each of lattice threads.
4. In the absence of breakages connect negative щуп to weight of the chassis and repeat check, indications should not change, infringement of quality of grounding of a lattice otherwise takes place.
5. For breakage localisation press negative щуп the voltmeter to the negative plug of a lattice of a heating element. Wrapped up by a foil positive щупом start to probe токопроводные lattice threads, moving from outside food givings to weight. In a point of breakage the instrument reading should fall from several volt to zero.

Regenerative repair

PERFORMANCE ORDER

1. Restoration of integrity of current-carrying threads is made by means of special two-componental electrowire paste of type Dupont № 4817.
2. Before to start regenerative repair of a lattice of a working element switch off a heater and allow to an element to cool down within several minutes.
3. Slightly smooth out the damaged site of a thread felt, then carefully wipe its spirit.
4. Paste two strips of an adhesive tape along a site of a thread subject to restoration.
5. Carefully get mixed up эпоксидную paste with a hardener (follow instructions applied in a set).

6. Put the received structure on the damaged site (with a tipping over approximately in 20 mm on edges of the intact thread) (address to an accompanying illustration).

7. Definitive polymerisation компаунда occurs in 24 hours after which protective strips of an adhesive tape can be removed from glass.
