OK, why a *930* tach? When I did my six conversion, I lost the 914 fuel guage location to oil pressure / temp. North Hollywood Speedo exchanged my plain vanilla 911 tach for a 930 tach with the boost gauge converted to a fuel gauge. Very nifty, except their "donor" was an oldie, and it has become intermittent. Already had it apart once, resoldered the pc board, connections, but I'm now thinking one of the components is tired. Can't read the values on the little square thingies (probably capacitors) anymore.

Can anyone help?
