I had the same problem of no Lambda/FV power but it was caused by the relay had not been aligned (soldered) properly when the RPM relay was built. I don't see a problem mounting inverted. If you can find a Green case you can install the circuit board either way. I sell a new solid state micro-processor controlled replacement circuit board if your interested....No relays to fail. --- In dmcnews@xxxxxxxxxxxxxxx, mike clemens <rmclemns@...> wrote: > > Group, > > Okay, either I'm the unluckiest guy I know, or Josh's > car just plain hates me.
