Thc question

Post by hehfarms »

New member here so be kind please. I just got my thc in last week and spent last couple nights installing and wiring it. The ohmic touch off is working properly. The floating head input is not working. I verified the switch is functioning correctly and the wiring is correct to input 1 on the tx board. With a multimeter I verified the switch opening and closing between input 1 and ground at the tx board.
The part that has me perplexed me is there is 24v between the ground on the tx board and input 1 on the tx board regardless if the floating head switch is open or closed.
