I'm now getting frequent missed gear engagements when I hit the starter switch. Could this be due to a slight "timing" difference between this setup and one solonoid/contactor? With the one Mazda solonoid/contactor the first thing that moves is the solonoid which throws the starter gear into the ring gear, then the electrical contact is made for power to the motor. So the gear is activated a little ahead of the contactor. With my setup, power gets to the motor at the same time as power to the solonoid windings so the motor is likely staarting before the gear engages. Any thoughts/ Peter Peter
