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

The working element of a heater of back glass represents a horizontal lattice from токопроводных the threads pasted on an internal surface has flown down. A food on a heater moves through the big safety lock from the block of distribution of capacity located in an impellent compartment of the car. Heater inclusion is made by means of the switch located on the panel of devices of the car.

Small breakages токопроводных threads of a lattice of a working element of a heater can be eliminated without dismantle of back glass.

Check

PERFORMANCE ORDER

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 negative 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.
To measure pressure during described below checks wind positive щуп the voltmeter with a metal foil which it is easy then a finger will press directly to токопроводной threads of a lattice of a heating element. Negative щуп a measuring instrument connect to the negative plug of a lattice.
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.
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.
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

Integrity restoration токопроводных threads is made by means of special ремнабора type Dupont 4817. The set basis is made токопроводная эпоксидная by the paste delivered complete with a hardener.

PERFORMANCE ORDER

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.
Slightly smooth out the damaged site of a thread felt, then carefully wipe its spirit.
Paste two strips of an adhesive tape along a site of a thread subject to restoration.
Carefully get mixed up эпоксидную paste with a hardener (follow instructions applied in a set).

Put the received structure on the damaged site (with a tipping over approximately in 20 mm on edges of the intact thread).

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