I have checked all other switches including the steer limit switches with everything working as it should. I have bypassed the entry bar switches as well to eliminate that possibility.

As far as the Oscillator card, i have never messed with that so i will do some looking in the maintenance book for that.

I did replace the potentiometer thinking it was that as well so it has a brand new one on it with the correct adjustment from the Ohm meter.

As far as the Inhibit Relay Board, is that the actual relay down by your feet below the contactor panel? I began wondering if that wasn't causing an issue as well. It does seem to make contact when it is supposed to but i know Relays can be sporatic as well. I would bypass it if i knew how to for sure but maybe that isn't an option. Also i have yet to find that actual relay in the book to order a new one but i will continue to look.

Thank you all for the help, i was pulled off this project for a couple of days to get some other priority items taken care of but I am back to this lift so any other thoughts as well will be greatly appreciated!!

Fact of the week
According to studies published in the English Journal of Medicine, the impact of daylight savings is revealed by a 24% increase in heart attacks on the Monday following the spring shift forward. When clocks move back in autumn, heart attacks drop by about 21%, suggesting that loss of sleep is an important driver.
