our lift won't stay running, it has burnt out the main module for the 3rd time , we bought it used. I believe the company we bought out from converted it to LP. We have replaced evrythingthethe converter, carb,the vacuum, the regulator and even some of the wiring, re[placed all filters,. we have had it running reallygood for only about 3 days, and it has again blown the main electric modular,. The guy at the place I have been buying my parts has helped a lot , but he only knows the gas parts or lp and converter. Can someone help we got a lemon....not knowing because it ran when it was delivered but all the safety wks and parts had either been taken off or bypassed we fixed all that too. We are at our wits end. Any Ideas and Thank you.
