A wiring diagram would be an excellent addition! Yes the neon continues to do exactle the same thing. When I purchased the m/s I thought I would get a solenoied as a spare. Although the new solenoid looks ok, I'm not so sure about the m/s as it seems to stick, therefore I've put back the original m/s. What kind of readings should I expect for the verious ares to indicate a malfunction. I'm happy to retest and feedback, the wiring diagram would be useful to ensure I'm test the correct connection.
