I have a bigas setup with 2 solonoid valves. One on the tank and one before the evaperator.
When the truck is going to switch over to lpg, there normally is a 'ratteling' 'clicking' noise because both solenoids get a few 12v pulses before they finaly open. (I tested this with a testing light)
Is this normal ?
The real issue is: sometimes we don't hear the solenoids noise and the engine stalls when switching to lpg
When I bypass he coil of these valves to the battery, they seem to work fine. And after that the truck runs for a few days untill the next time it stalls on switchover to lpg.
Is this a valve problem ? Or the coil ? Both ?
Or something else ?
Of course when I took it to the lpg shop, it was running fine with no errors in the lpg memory. :-/
