I'm assuming you have already checked wiring and have the LO switch and HI switch in the right places. They look the same but are set internally at completely different pressures. You can open them by removing the 2 little nuts off the tiny treaded rod and then slip the case up the wires. Inside you'll see small springs under compression. The HI switch springs are under more compression than the LO. Turn the little internal nuts to remove compression to lower the point that the micro switch triggers. This requires a little fooling around to get it right but be sure to back off the nuts a turn or so (less spring pressure) when you've found the trigger point.
