- wiring, ground to trunk is fine (actually it is hard to do something wrong there
)
- pump is ok and working (directly put 12V on it, disconnected FCM and water was comming out from thick water line). If I connect thick line to FCM (with FCM "connected" to main module and "S" light lit) and put 12V on pump, no water is comming out from thin water line ("out" of FCM).
- Relay looks fine (to me
)
- BUT under "TST" mode NO sygnal is comming to red/blue thin cables - this means that main module doesn't give proper signal.
