I flew the Archer this morning. This afternoon, I made a wiring harness for the Slick-Start Magneto Booster and wired it up. I then wired the shielded #22 wires to the Amp Shunt. I also tested the start switch with my Fluke to make sure the magnetos were correctly grounded through the start switch. Both mags are grounded when the start switch (SS) is off. The right Mag is grounded when the SS is on L. The left Mag is grounded when the SS is on R and the right Mag is grounded when the SS is in the START position. All checked out.
