Hello all, I recently posted about some tach troubles. Well I have it all in the dash, mock jumper bar and everything. Signs of life, but no life. When ign is on, it jumps to zero, so I know it’s getting power. When I start the car, no rpm’s show up. I can tap the needle and it’ll go back to zero, but no rpm’s. Tried the jumper bar in both the 6 cylinder and 8 cylinder configurations and both had the same results. Anyone know what’s up? (Pic with volt guage to show engine is running)
