- Rated resistance at 20°С — 30-34 Ohm
2. (In addition to 2C engines). Connect battery power to valve terminals as shown. Blow into the nozzle "E": air must come out of the nozzle "F".
If battery voltage is not applied to the valve terminals, then air should not flow from the fitting "E" into the fitting "F".
3. (For 2C). Measure the resistance between the valve terminals.
- Rated resistance at 20°С — 37-44 Ohm
Connect battery power to valve terminals as shown. Blow into the nozzle "E": air must come out of the nozzle "F" and should not come out of the big choke "G".
If battery voltage is not applied to the valve terminals, then air should not flow from the fitting "E" into the fitting "F" and must pass from the large choke "G".
