| Measure the resistance at the connector between contact “13” and the heater housing. |
Note | t
| If a voltage of 12 VDC is applied to the combustion air blower -V6-, the current input is between 2 and 3 A. |
| t
| The internal resistance of the combustion air blower -V6- is between 3 and 6 Ω (40 Ω if the combustion air blower has not been in operation for a lengthy period). Resistances of less than 10 Ω can no longer be measured with the required accuracy using workshop equipment. The internal resistance test can therefore only be used to detect major component damage. |
