1. Disconnect the socket from the AKP electromagnetic valves. | 2. Measure resistance between each contact and "weight". Resistance: valves No. 1, No. 2: 12–16 Ohm valve of adjustment of pressure: 3,3–3,7 Ohm blocking valve: 11–15 Ohm | Prevention
Valve No. 1 (switching 1–2,3–4): To Valve No. 2 (switching 2–3): L Blocking valve: J Valve of adjustment of pressure: G, N |
3. At discrepancy of values check existence of gaps or short circuits in wires. Replace valves. | |
