Hello All,
I have had an intermittent rpm issue, if I turn my high beams on, the tach goes to zero.
High beams on=no tachometer
High beams off=tachometer works fine
So the other day I went out to start the truck and both of the turbo lights and the low fluid light is staying on.i have pulled the gauge cluster, checked for loose connections and disconnected the vacuum switches for the boost lights and replaced the fusible links for the Main/Glow.
The issue still persists.
Perhaps the injection pump rpm pickup?
