|
3. In turn connect щуп the voltmeter to the center of each current-carrying strip of a heater of back glass. The voltmeter should show tension about 6 Century. |
| 4. If the voltmeter shows tension above 6 In, the current-carrying strip of a heater means has break from outside between a point of connection of the voltmeter and the party of a heater connected to "weight". |
