Followed Redbeards instruction to the letter and when test running the rig the control doesn't work. I used the modified switch instructions and it tested good on the bench. I ran the grey wire to the white wire on the speed sensor connector near the main fuses. When I have the motor running and push the (On) button I get the led (on) light to turn on and stay on, the engaged led also comes on momentarily and then turns off. But, when I get up to speed and push the s/c button nothing happens Any ideas to the guys who have been thru this?
