The Plot thickens. I have two supposedly identical switches. One tests for continuity going CCW and the other test for continuity going CW. I currently have the CCW to ON and my ammeter is constantly the hot lead so I put that on one terminal alone. Everything else got divided among the balance of the two terminals. With the ignition switch to ON, the electric pump comes on and everything seems copacetic .....except my Tach stopped working. WTH?
