13.6.2.8) Three-way solenoid valve
See Pic. 189.
The threeway solenoid valve Q is installed on engine frame.
➪ Check for physical damage
➪ check for air passage
For removal of the air pressure hoses refer to chapter 13.1.11.
➪ checking the mixture enrichment (dynamical)
For that fit a T-branch into line between solenoid valve and float chamber
to facilitate the measuring by pressure gauge of the pressure rise at
exceeding the airbox pressure of 1250 hPa. The T-branch may remain but
for normal operation it has to be securely closed.
➪ Reading of resistance between the two terminals W :
- Sever plug connection with wiring harness but re-establish straight after
completion of check and verify tight fit and engagement of catch.
- resistance at 20°C: 28,3 ÷ 31,1 Ω
■ ATTENTION: At physical damage, mechanical defects or readings out-
side tolerance exchange the threeway solenoid valve with-
out delay.
