So I have installed a Surefly e mag on the right and have had a Bendix impulse mag on the left. I have an ACS 510-2 start switch. I wanted to ground the left mag (Bendix) during the start and let the Surefly do the start, so I ran a wire from the ground (Jumper side for the right mag) to the left mad terminal thinking it would ground the left mag and leave the Surefly on the right to fire. Nope. Instead it grounded the Surefly on the right side and kept it grounded. So is there a way to ground the left mag and let the right mag fire with this type of ignition switch?????
