Sorry I an not familiar with the term.. Do you mean the rollover shutoff?
If that is what you are referring to I would take it out and give it a good five minute shakeing and then reinstall it.
I never had one apart but I am told the rollover switch has a ball inside that disconnects the lectricity when inverted.
Before getting a new one I would try to get the ball back in it's place..
If I needed another one I would ask everyone on eBay that was selling Jeep parts if they had a used one.. That has always worked for me.
